    If you add on the rim a second Allen opposite the first you eliminate the vibrations,otherwise try another kind of wheels like sponges 1/24 Scaleauto 21 x 13

    Our 962 "coke" runs perfectly since 2009 still with the original engine and transmission, only oil and grease after this balancement of the rear wheels
    I race these BRM's on commercial tracks so I only use the foam tires. All tires have been trued and are perfectly round. I always use two allen screws...just in case one works loose.

    Again..,thanks for your input.

      binding on body and broken motor post

      I have a new pinion and a new crown gear and a brand new perfectly straight rear and front axle. The chassis running on the track without the body is pretty quiet. However, when I put the body back on the car gets noisey. I am checking the tires binding on the body as maybe the cuprit. I am also thinking the body must be binding on something to cause the vibration and subsequent noise.

      If anyone has any other suggestions let me know. I appreciate the input.

      OK...more work on the 962...

      Last night I did find some binding on the chassis to the front of the frame/body and eliminated it. Also the lead wires were slightly stuck under the front of the interior thus causing it to ride a bit high and pushing the interior up against the top of the body. Adjusted that and now the body is floating a bit more freely.

      Also found the motor post was cracked and may have been allowing the motor to vibrate under power. Glued that and it seems to be holding.

      I will test it tonight and report back here.

      Thanks everyone for your input.
