[mk351e]

ooooooooooohh. OK. SO, let's say I gear for 60mph with a 1515 neu. I run on a parking lot wot most of the time, and all is well. THEN, I leave everything except the wheels alone, I go to a track, and I'm not running wot, but on and off for a smallish track. Am I asking for problems here??

PS - thanx for all your help linpimp, and thanks for helping me find those pinions. Do you know what grade of steel is strongest there?
