First night on my TA05 on rubber tires and Ozite. Didnt have any real success as far as set-up, etc. as I almost never run rubber tires (once every few years). BUT_I can say that it ran consistently, diffs are perfect (stock ones), and it had very good speed-both accelerating and top end-even with the stock belts. Although I had universals on it-I ran with the stock shocks so it was darn near bone stock. I would NEVER guess a heavy, all plastic $140 car could be so fast..
