Since you have a Banshee I can offer some advice for TT's. I'd get a -1 Swingarm right away. A-Arms are your choice. If not run offset rims infront. 6 Inch wide in front and 9inch wide in rear. ( some guys run 10's). Shocks are an absolute must over a lowering kit. You probably already know this though. Camber, well my friend runs stock a-arms so that can't be adjusted, but toe in is always a personal preference. Usually 1/4 inch toe in or so and as stright up as possible on the long ovals where minimal drag is the key. Also spend as much time as possible to get the machine to roll easy, Less drag is very important.

I've seen Travis Spader's TT banshee first hand, at wayne county speed way, during the National race 2 years ago. To say a banshee is bad for TT is the wrong thing to say. Im not defending the banshee because I have one, I love 250R's too, I just know what one can do, because I saw one dominate at the nationals. And by the way He LAPPED all but 3 quads, given another lap he could have passed them. And what was everyone else riding BIG BORE 250R's.
