the truggy is very solid right outta the box....but u will need alum rear hubs forsure alum servo horn and really u can dial it in from there....i am running a very aggressive setup on my truggy, but i am running 20-20-10 on the diffs and 35-32.5wt w/1.3 pistons on shocks...white/orange springs
but check out tytessman.com for some hb tricks and setups as well....
goodluck
