lst2inIraq

Got the werks 3 port comeing over here for my buggy, sportwerks mayhem. The track we built is loose,dusty, and rutty, med in size with med jumps not to tech. Was running my lst2, this is my first buggy to learn on and looking for a good clutch shoe and spring setup for this track.
Can I use the stock flywheel or is there something better, also thinking of useing 15t bell and JP-2 pipe to get some top end, what do you all think?
