  • BRM rules 2015, Classic 512 and 917 will be added soon..

    These are the current BRM rules as used in the 24 Hours of Tacoma last year.
    Did not get posted separately so doing so now.

    The Classic ( previously 917 ) Class will be updated for the metal chassis soon.

    We will be updating the 917 rules adding the 512M and the metal chassis for the 917. This will not be done until we release the 917 with a metal chassis, as tooling changes make it impossible until production is available for weights etc.

      INTRODUCTION

      This International Rule Book is intended to define the technical regulations for all official BRM competitions to be organised by BRM Model Cars Official Distributors or BRM Model Cars directly.

      The main purpose is to enable all slot racers who want to participate in BRM Challenges in every part of the World, to have the same possibilities of tuning for their models.

      This will allow International competitions, with the same models and specifications used for all National and International BRM Challenges.

      These Technical Regulations can be applied both for sprint races and endurance races.


      THE NEW PHILOSOPHY IN 1:24 SCALE MODEL CAR SLOT RACING

      The mission of BRM is to create a really new Philosophy for Model Car Slot Racing in 1:24 scale.

      When BRM decided to start, it was because they were convinced they should launch on the world market a new type of slot car model, completely different from any other in this market. A truly new philosophy. A simple model, easy to drive, fun, with good performances and, above all, a beautiful scale model of a real racing car!

      And since driving those models is fun, they thought of this International Rule Book, which will apply to all Sanctioned races to be held with BRM models in North America.
      The BRM racing philosophy is simple. It is racing for tuned, not modified cars. The race is more about the Racers and less about modification. It is about a more realistic driving experience. One where the driver has to think about their actions and protect their car by driving with that in mind. If you lose a wing in a crash you have to repair or replace it under green - just like the real thing! This realism helps people drive with a difference frame of mind, one that is more realistic.

      The BRM CARS


      Car models eligible for BRM Challenges: are
      All BRM Group C cars on general release both inline and angle winder are legal.

      New models will be allowed in 2014, only in the same category (Group C).
      Other classes are planned; those will be added to the regulations at a later date.
      All the parts of the model must be the ones used in the box stock car; they must be fitted as supplied by BRM.
      Their replacement, or any modification, can only be done according to the rules herein.


      CAR BODIES


      Bodies must be complete in all its parts, except mirrors, front winglets, wipers, antennas, and tow hooks. Filler caps, glass and all interior parts must be fitted at the start of the race.
      The body cannot be modified in any way nor may it be made lighter by sanding or any other means**
      Bodies may be bullet-proofed with Shoe Goo, but it is not allowed to use Shoe Goo as weight. (do not empty a complete tube of Shoe Goo as a way of adding weight to the body!!) You can re-enforce headlight buckets, details like filler caps, windows from the inside, rear lights. On the Toyota you may add Shoe Goo to the side parts of the body to keep them in place (multi piece body). The intent of these rules is to allow strengthening of the body to help prevent crash damage, not to tune the car. Excessive reinforcement may create a situation where you are asked to remove added weight (glue) Light kits, when fitted may be Shoe goo’d in.
      Body kits can be used, but they must be completely painted so that no unpainted areas remain (no clear coat only on white plastic).
      The body weight should be no less than the standard box stock bodies.
      Body minimum weight limit:
      Porsche 962C with rear wing type “A” gr. …40
      Porsche 962C with rear wing type “B” gr. …40
      Porsche 962 IMSA gr. …40
      Porsche 962C short tail (European Version ) gr. …38
      Toyota 88C (without rear wing, fixed to the chassis) gr. …34
      Sauber Mercedes C 9 with wing fitted to body gr. …46
      Both types of body mounting systems are legal on all models, early Porsche bodies may be modified to replicate the later O Ring type bodies**
      You can either use the quick fit system on later cars, or fit a washer to retain the body, preventing the body from coming loose in a crash. You may also use clear tape on the side of the body to retain the body in a crash.
      Porsche bodies may be attached to the chassis using the provided screws and washers, screws must be stock length, no car may be raced with loose body screws. Early Porsche bodies may be modified to later spec, see below **
      Washers may be glued onto the screws, for faster assembly. ( early model only )
      Later Porsche, Toyota and Sauber Mercedes bodies must be attached to the chassis with provided screws (fitted to bodies) and O-Rings (fitted to chassis) ** early Porsche cars may be modified to the later O ring mount system. They must exactly replicate the later version if this is done. O Ring body mount systems may have washers fitted to disable the quick fit body mounting. All cars can use the non quick fit body mount, by adding a washer below the chassis to block the quick release if so desired.
      Only original BRM screw sets are allowed.
      Windows must remain transparent. Only tampo-prints as included in the standard models or decals added in self painted kits, with the same size are allowed. Windscreen must be fitted to the car at all times.
      Rear wing attachment can be reinforced with glue, tape or sponge rubber, provided the body shape is not altered. No tape is allowed on the top surface of the wing.
      On the Big and Small wing Porsche you may use a small piece of tape from the endplates to the side of the body to reinforce the wing. Toyota’s rear wing mount may be taped to the chassis, or may be glued into the chassis.
      Sauber Mercedes with the magnetic wing can have a small piece of tape to retain the wing to the body only through the center of the wing upright.
      Car can’t be raced without the Rear Wing. If it comes off during the race, it must refitted or replaced immediately, (within a lap, or the car will not be scored for that segment of the race). This must be done under green Track conditions. No replacement of Body or Chassis is allowed during a Race. You must repair the damage and pass Technical inspection before re-entering the race if the car is pitted for damage or repairs. Any minor parts that are lost during the race must be refitted before the next race. (Wheel inserts Headlight buckets, etc.) Any car running with headlight covers does not need the headlight buckets i.e. Coke and Miller cars.
      No repairs may be carried out during a lane change, all cars must be replaced in the Pit Area on the Track, work can only resume when the race is restarted.

      MODEL CHASSIS

      Straightening the chassis is allowed, filing the chassis (other than modifications mentioned) is not allowed. Opening body mount holes other than to fit O Ring mounting system is not allowed. Nothing else may be added or removed from the chassis.
      The chassis can be cleaned from injection flash only.
      Trimming of the front edge of the chassis to allow braid clearance is allowed. Also you can modify the front of the chassis to fit the S-026SS race guide. No modification to axle mounts or bearings permitted, you may glue in the rear axle bearings but not modify their fitment in any way.
      In the Porsche 962C chassis (first production), is permitted to modify chassis to allow adjustment of rear wheels and gear. But only in the same area as the IMSA Car chassis, no extra plastic may be removed. You may also convert to the later body mount system using O-rings. Motor shims are allowed on early chassis.
      All cars can be converted to angle winder or run in line. If converted to angle winder you may modify the interior to replicate the later interior.
      Magnet is forbidden, magnet retaining strap may be fitted.
      Adhesive tape is allowed under the chassis to prevent the loss of screws that fix the body. Cars that lose screws during a race will be penalized, especially if such action causes a problem to the track or another car. (Suggested penalty 100 laps Endurance Race, 10% of heat total Sprint Race). Tape can be used to control the body movement.
      The cockpit, the dashboard and the driver must be present at all times and regularly fixed to the frame, as per specifications contained in the assembly instructions of the original BRM kits.
      The cockpit, the dashboard and the driver must be painted.
      You may glue the driver into his seat and glue both parts of the interior together on models with this type of interior.


      FRONT AXLES, FRONT WHEEL HUBS/TIRES

      Maximum front wheel width tire-to-tire are:
      for any Porsche mm. 82
      for any Toyota mm. 82
      for any Sauber Mercedes 82
      In no case may the wheels and tires be visible outside the body when viewed from above. (also in the case of front axle floating).
      Only original BRM front tires or S-022S lowered front tires are allowed. It is possible to lower stock front tires, but it is forbidden to treat them with glue (or similar) for limiting its grip - may be made slightly conical section, but the outer diameter of the front tires can’t be less than 23mm, the inner edge must be equal or bigger than the outer edge of the tire.
      Front wheel hubs must be complete with original inserts; the type of insert to be used may be chosen from among those in the BRM catalogue and must be fully assembled and painted.
      Only original BRM spacers between chassis and wheel hubs are allowed; they could be in Teflon, Brass or steel with the aim of achieving the maximum width allowed.
      New accessories of this type will be allowed in the future, if specifically notified by BRM Model Cars, with special modification of this technical regulation.
      Front axles must be BRM product, no drill blanks are allowed.

      REAR AXLES, REAR WHEEL HUBS/TIRES, CROWN and ANGLEWINDER GEARS

      In no case, may the wheels and tires must be visible outside the body when viewed from above.
      Only original BRM rear tires are allowed:
      For Plastic tracks S-020, S-020S, S-021 and S-021SS can be used
      For Wood tracks S-021 and S-021SS.
      When race tires are supplied by the race organization, type and size will be decided by the race organization.
      It is possible to turn the rear tires, but their diameter must not be less than 27.5mm at the start of the race. If the outer diameter becomes less than 27.0mm, tires must be replaced immediately with others of the same type. You may radius the outer edge of the BRM S-021SS sponge tires to assist in body clearance; you may not modify the body. Inserts must be fitted to the wheels.
      Only original BRM bearings are allowed; they could be in Teflon or Brass. Rear Bearings may be glued into the chassis. It is absolutely forbidden to change their position.
      Original BRM stoppers are allowed, Toyota and Porsche gear mesh spacers and S-012SS shims are also allowed to set gear mesh. Angle winder cars may use stoppers.
      Only original BRM spacers (same as 6.4) are allowed, with the aim of achieving the maximum width allowed.
      All BRM crown and anglewinder gears are allowed.
      Rear wheel hubs must be complete with original inserts; the type of insert to be used may be chosen from among those in the BRM catalogue and must be fully assembled and painted.
      Rear axles must be BRM product, no drill blanks are allowed, you may flat spot the rear axle to prevent gear slippage.

      GUIDE BLADES (PICK-UP) AND CONTACT BRAIDS

      Only BRM Guide Blades S-026, and S-026SS* (Pick-Ups) are allowed. Must be held in place by provided BRM O-Ring in correct stock position. The O-Ring holding the guide may be glued to the post. Only one O-Ring is allowed on the guide post. S-026SS is held into the chassis with a screw, this is allowed only on this guide.
      It is possible to use shims between the guide blade and the chassis (guide shims), in order to make the front axle more efficient.
      Only original BRM guide shims are allowed.
      All BRM Contact Braids and spares are allowed.
      Braid juice or chemicals may not be added to the braid at any time; braid may be cleaned with a brush only.
      Braids may be re-set by a Corner Worker in the Event of a crash. No other work can be done Trackside at all.


      MOTORS, PINIONS

      Only original BRM Electric Motors are allowed:****
      BRM T-027 motor ( S-031)
      BRM T-RS motor (S-032)
      BRM T-RS EVO (black label) designed for wooden tracks (S-033)
      New motors from BRM may be added to this list
      .
      Only original BRM pinions are allowed; the number of teeth of the pinions is of free choice.
      When race motors are supplied by the race organization, they may be handed out with pinion and power cables. Type of motor and pinion will be decided by the race organization.
      Motor and pinion cannot be changed unless under race direction authorization. This must be observed by a Race Official.
      Motor cannot be fastened to the chassis by glue or tape.
      Any maneuver to increase the motor's performance is forbidden, included running-in and use of performance enhancing liquid. To this purpose, the motor shall be assembled under scrutineers surveillance during pre-race technical verifications and lubrication will be done with oil provided, or approved by the organizers.
      Removal or opening of the identification label on the motor is prohibited. Motor leads must remain as supplied by BRM, motors supplied for in line cars may have their lead wires lengthened to fit in the angle winder chassis. Attachment eyelets may be soldered to the wires.
      If fitted with a wood track guide, may modify lead wires to that fitment type.
      New motors may be allowed in the future, if specifically notified by BRM Model Cars, with special modification of this technical regulation. Also race organizers may spec a motor of their choice from BRM.


      WEIGHTS AND BALLASTS

      The minimum weight for any BRM car in running order is set to 180 grams.
      The use of brass shaped weights, specific to each model and produced by BRM, can be used for balancing the model. No other type of ballast is allowed.
      Shaped brass weights must be fixed in the chassis in seats of the same shape, with bi-adhesive tape, if used. You can double stack weights, but cannot cut them or add other types of weight.

      LIQUIDS, OILS AND GREASES

      May use oil or grease to lubricate motor, gears and axles.
      You may lightly sand tires - no other chemicals or additives allowed.
      No tire treatment of any kind is allowed. If running BRM -021SS tires the SC-5300 Scaleauto tire cleaner may be used, tire bite or grip may not be used. This will only be at the tech table; no work at all can be done trackside. (Scaleauto tire cleaner will be supplied by the Race organizer.)
      Races may be run on Plastic Tracks or Wooden Tracks. BRM prefers races to be run with Rubber tires on a clean track surfaces. However certain Clubs and Commercial Track run glue, if this is the case tires will be supplied to suit the track conditions however no fluids or glue may be added to the tires or track surface by the Racers, only treatment allowed will be done by Race Officials.
      No treatment may be added to the braid on the car, or added on the track.


      CONTROLLERS

      Any type, even self-built. The maximum voltage and maximum current available at the throttle's contacts must not be larger than those provided by the power supply, and the lowest available voltage must not be any lower than the power supply's ground.







      RACE PROCEDURES

      Race procedure for BRM 1/24 Scale Model Car Slot Racing.

      In building accurate Scale Models for racing BRM believes the Aim of the New Philosophy of Scale Racing is to race in a realistic manner.

      To that end it is up to drivers to protect their equipment (the Car) during the race.

      If a rear wing is lost it must be replaced immediately under Green (while the race is still running). If a heat ends while repairs are being done, work must stop until the next heat starts.

      Repairs should be done on an allocated Pit Table in clear view of all Racers and Officials.

      No car may be removed from the Race and taken to any area other than the Official Pit after qualifying and technical inspection. This is to ensure Fair Play for all Racers.

      Sprint Races can be run in many different formats, this must be clearly published well before the race so all traveling Teams are aware of the regulations and Procedure for the Race.

      Endurance Races shall be run for the Published time of the Race i.e. a 4 Hours Endurance Race must feature 4 Hours of running time.

      The only exception to this is the suggested time for lane changing (usually 1 minute) which may be deducted from the running time.

      So a 4 Hour Endurance Race on an 8 lane track would run for at least 29 minutes per lane.

      No work can be done on the cars during lane changes, only sticker replacement and the lane change is allowed.
      No inspection of the car during lane change, no checking temperature of motors or condition of braid or tires. These must be done in the Pit Area under Green (while the race is running).

      In Endurance races the Power shall only be turned off for a problem with the Track or Computer Equipment no Track or riders calls are allowed.

      The idea of BRM Endurance Racing is to test Driver and Equipment, track calls and Rider calls encourage overly aggressive driving and reward such actions.
      The idea of a BRM Endurance race is to replicate the experience of Real Endurance Racing where the Clock runs continually for the given length of the time of the race and the Drivers are challenged to control the fate of their cars for that time.

      This is the challenge, if you put your car in harms way you may have to endure damage, this is part of Endurance Racing.



      Parke Fermé
      Once cars have passed Technical Inspection they shall be placed in Parke Fermé until the Race Starts.
      No work may be carried out after Technical Inspection and Qualifying if held.
      Any car broken during Qualifying may be repaired or replaced but qualify as last. Once the race has started no car may be replaced. Only Chassis and Bodies that start the race shall be recognized as Official Finishers.
      Repairs during the Race
      Introducing their car to the Technical Inspection, each Team must deliver to the Race Direction, who will store it in a team private box, the spare parts deemed necessary for the entire race, respecting the following rules and list (suggested quantity per spares allowed): Subject to race distance and Event organizer.
      Body and Chassis cannot be replaced. It is legal to repair damaged threads on BRM chassis or guides with glue; however that glue may not be used to hold the parts together. If glue can’t repair the part it must be replaced. (Chassis may not be replaced during the Race).
      Shaped Weights: not allowed after Technical Inspection. Once the race starts weights may be changed under Green (while race is running).
      Tape, to repair damage, hold on weights etc.
      Guide blade, with screws and O-Ring: 2
      Guide Shims: 4 of each size
      Contact Braids: 2 pairs (Must be clean and dry, no additives allowed).
      Motor Retainers: 2
      Screws and washers and O-Rings (to fix body to chassis): 2 full sets
      Crown or Angle Winder Gears: 2 of each size
      Pinions: 2 of each size
      Bearings and Spacers (in Teflon or Brass): 2 full sets
      Stoppers: 2
      Wheel Inserts, front plus rear: 1 full set
      Front Wheel Hubs with Tire: 2
      Rear Wheel Hubs with Tires (handled out only)
      Motor (if handled out only)
      No Complete BRM Chassis or Bodies shall be in the Teams Pit Areas during a Race, anyone found with duplicate cars or chassis to the one entered in the Race will be disqualified.

      Tools allowed
      Screwdriver
      Key Allen
      Knife
      Adhesive tape
      Glue (only for plastic parts reparation)
      Cleaning rag
      Soldering Iron (supplied by the Race organizer)
      Lubricating oil (supplied by the Race organizer)

      After the introduction of cars in Park Fermé, any intervention of repairs and/or inspections must be carried out in the Pit Table in clear view of all Racers and Officials under Green (while the race is running).

      When building your BRM Car to race in the BRM Challenge all parts must be fitted in the correct place designed by BRM, fitment of BRM parts in a different position than designed, or held together in a different way than designed is NOT LEGAL.



      And finally, anything not expressly permitted by this Rules Book is prohibited.

          917 / 512 Rule question

          Will the 512 be required to run with wings or winglets?

          Comment


          • #6
            Both 917 and 512M will run with winglets.

            Yes you read it right the 917 will have the center winglet. All cars must have the winglets on at all times or they will not be scored.
            If you lose the wing repairs must be done under green only and wing must be refitted in original position.

            We are Scaleracing after all!!!

              I am not sure where I "read it right". Until you replied I did not know that the new 917 would have a winglet and I have not seen the new 917/512 rules. Where are they posted?

                Sounds like an advantage has been given to the already privileged 917!


                That center wing will be harder to hit but easy to aim for.


                Do the cars come with instructions on assembly or are they assembled and complete ready to roll?

                How capable is the assembler??

                  We have not posted rules as for this race none are needed yet.

                  You get and all allowable spares in a box. that is all you can do to the car use those spares.
                  Basic rules apply, car cannot be too wide etc.

                  But until after this Event there is no need for a rules set as you will only be able to create your race car set up from the supplied parts.

                  You cannot modify the body, except built proofing.

                  Will hand out a what you can do sheet on the day with the car. That way everyone is at the same advantage or disadvantage. No one knows the set up, No one knows if weight can be added, etc. Not till race day, then you create the best car you can with the parts supplied. Should be fun to see what you all can do.

                  Normal BRM race rules will apply, wings must be on the car at all times, all repairs must be done under green at the Tech/Pit table only.

                  Getting close now

                    RE the 512/917 Enduro cars...

                    Only the parts in the box can be used?
                    So will there be enough shims to tune and adjust out any warpage of the motor pods and space the wheels properly?

                      A section of Current Rules

                      I know it is time consuming, I've been updating our rules for 20 plus classes that we run for most of today. BRM cars take up about a fifth of that and we run according to your rules but with some minor local rules for local flavor. As I generate these rules on both our Yahoo group and our Facebook group I need to copy and paste link locations for the various classes and the way it is now the latest rules are scattered around on this thread and it is time consuming and even confusing to my somewhat tired and frazzled mind to hunt through too much information for the updates. I just found a newer Group C version than what was at the top and now I have to go back and edit two posts... Whah!
                      Would it be too much to ask to have the latest sections pinned at the top of the thread?

                      Many Thanks Alan,
