Novice MX'er
 

I want to start racing mx on my raptor and i need help on what to purchace. I figured a good start would be widening it and more performance parts. Money could be a slight prob but i can work around that also would my rear wheel spacers hold up to the abuse of mx. Whats the best setup i could go with from the following: Shocks, a-arms, axle(depending on spacers), pipe and anything else i should add.
