Taz, We aren't allowed to use anything on the tires (including sun block) but the grip is quite good. In the first heats it is a little loose but by the final round the cars push round some corners. The good set-up for the last couple of rounds is pink soft in the back and pink medium in the front, most people use this all the time but others use gold rears in the first round.

PS: I haven't experienced the grip roll I was warned about yet

Are there any good ways to mount the servo? Mine came with little plastic blocks and they're not very strong.
