Does anyone have any pictures on how to distribute the weights in their ladder car to be the most competitive and keep the 3/4" COG from the rear axel? I find that I can only put 10 of the 1/4" tungsten weights behind the rear axel and the rest spread between the front and rear axels. Also I tried to do my own gig a loo prep of the wheels and axels for oil yet wasn't sure of the best way to do it. I used the soft pipe cleaner and a drill to do the inside of the wheels and sprayed it on the axels and let it dry. Any help is much appreciated. Also is there a step by step of how to build a competitive pro car to view?
