1. 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.
2. 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.

New models will be allowed in 2013, only in the same category (Group C).
Other classes are planned; those will be added to the regulations at a later date.
3.2 All the parts of the model must be the ones used in the box stock car; they must be fitted as supplied by BRM.
3.3 Their replacement, or any modification, can only be done according to the rules herein.
4. CAR BODIES
4.1 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.
4.2 The body cannot be modified in any way nor may it be made lighter by sanding or any other means**
4.3 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 re-enforcement may create a situation where you are asked to remove added weight (glue) Light kits, when fitted may be Shoe goo’d in.
4.4 Body kits can be used, but they must be completely painted so that no unpainted areas remain (no clear coat only on white plastic).
4.5 The body weight should be no less than the standard box stock bodies.
4.6 Body minimum weight limit:

4.6.5 Toyota 88C (without rear wing, fixed to the chassis) gr. …34
4.7 Both types of body mounting systems are legal on the Porsche models, early Porsche bodies may be modified to replicate the later O Ring type bodies**
4.8 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 **
4.9 Washers may be glued onto the screws, for faster assembly. ( early model only )
4.10 Later Porsche and Toyota 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 not have washer fitted to disable the quick fit body mounting. The only cars that can use the non quick fit body mount are cars offered that way BRM001 through BRM010. All later production BRM011 through BRM021 can only run with the quick release system, no washers may be fitted to the body screws of these cars.
4.11 Only original BRM screw sets are allowed.
4.12 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.

4.14 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 re-enforce the wing. Toyota’s rear wing mount may be taped to the chassis, but must be able to be removed; it must not be glued into the chassis.
4.15 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.)
4.16 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 re-started.
5. MODEL CHASSIS
5.1 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.
5.2 The chassis can be cleaned from injection flash only.
5.3 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-026SW 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.
5.4 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
5.5 Magnet is forbidden, magnet retaining strap must be fitted..
5.6 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 not be used to control the body movement.
