what would be the best things to try to eliminate traction rolling on a high bite carpet track?
would weight placement in certain areas help?

I would love to have a brass suspension holder for the mm car in the rear. The one that is right by the motor. Having a little extra weight right by the motor would really help the handling one would think. I saw the TLR 22 has something like this and it makes total sense to me. I don't need weight out the back, I want it close to the motor.

Looks as though the B5's have that option as well. I can only guess that Kyosho will eventually follow suit at some point. I'd be betting on GHEA to have them first. LOL.
