racerDave-I use washers to space out my wheels. PLain old washers!! WOrks great.
Peter-can you enlighten me on some carpet/foam tire set-up info. If not a set-up per se-at least what worked and what doesnt!!!
My car is quite good right now on our new layout-but its low-grip. I fear when the traction comes way up (by next race I think), the cars steadily going to deline in performance! compared to the TC3 and X-S's.!!
