I raced a few quads, both in the woods and on the strip and the RZR does pretty well. I just have the basic stuff like a clutch kit, pipe, bla bla bla. I mean if you're going to be racing quads that are of the sport variety you will have your hands full and will most likely lose in a drag, but utilities are another story. Plus if you can get most of them in the woods you have a distinct advantage because you can really stick your neck out because you don't have to worry about being maimed if you wreck....
