American racer flat track tires WIDE ass rims with an extremely wide offset then an axle,a-arms I reccomend the ASR since your not gonna be in mud or even that much dirt for that matter and the Heim joints will be fine in that.Then get a pair of some comfortable aggressive bars KX Low bend are my preffered bend very straight and wide. The trick to any racing is to get yourself as comfortable on your quad as possible set your levers up so you can reach them easily while leaning off the quad little things like that are what seperate the winner from the also rans.
