Rear hinge pin holders, steering rack, rear camber block, and ball studs pulling out of caster blocks are what I've seen break. Aluminum holders, Exotek rack, long ballstuds with a nut on the bottom of rear inner ballstuds, and long ballstuds in the caster blocks have solved those issues for me.

i can't imagine needing any of that outside of the normal parts, no need to get all aluminum, they beefed up a few parts from the RB5, i'd say grab towers, the exotek rack, arms and front hubs. they say you need the long studs and i bought them, but haven't put them on, just use the set screws in the other positions..

the buggy is solid.

What is the reasoning behind ditching the new gull-wing arms and gong back to the older straight ones?
