I haven't seen it done on quads, but just a thought, say its a left handed oval, you only turning one way, maybe an adjustable axle adjusting in on the inside and out on the outside with stock a-arms in and +3 out. Also I do believe you can go too low and not have the weight transfer to turn properly. If you really want to get creative you can play with the ackerman and caster too. you also want to measure the circumfrance of the tires, bigger rear on the outside. Nitrogen my give better inflation in the tires.
