Get yourself some +2+1 a-arms for a start and shocks to go with them. I highly recomend Elkas but if you on a tight budget yfz450 shocks will do. As for the swing a-arm its more of personal prefrence. Im personally gonna go with a -2 to balance it out the best i can and i need all the traction to. I ride woods a good bit myself from what iv read -1 seems to be the way to go. Also if you still need to get alittle bit narrower than +2+1 a-arms get 4-1 offset rims they will take 2 inchs off. hope this helps if ya got any more questions just ask.
