duh, i forgot to add your going to want a wider axel. beadlock tires for those huge jumps, and good MX tires becasue i thought you said you are going to start racing. get the frame powdercoated so it doesnt look like a turd, and maybe get some nice chrome PT pipes. i think you are going way overboard on suspension here and are forgeting about one crutial thing, POWER. most people, like me, add power before suspension thinking whatever,i will be fine. your not going to be keeping up with highly modded 450s on the track with a stock banshee. you want a MX port job, which will give you all the power you need. if you want, my who;e passion racing port job, noss head, pisons and everything came out to like $800 and i am very happy with it. dont put the 600 in bling, this 800 got me pistons, bore job, port, and a cool head. so what would you want 750 for bling and pistons, or 800 for ported, pistons, and cool head( which is bling too). think about that. i better stop myself, i can go on and on
