For that price you are gonna have to buy used parts. But I would go with a set of +2+1 a arms and a set of good shocks. Axis,elka,tcs,pep,fox those are the better brand shocks. You can leave the rear stock except for the axle. Go with a +4 axle. The next step would be a good rear shock and a -1 or -2 round house swingarm. Maybe even long travel. But that's when things start to get expensive.
