Mountainspeed make a upgrade kit for the FSR ,it includes fully sealed bearings for all pivots and a longer aluminum bracket which the bottom of the rear shock bolts up to. It increases the rear travel from std 4" to approx 6"and the sealed bearings eliminate any traces of "stiction"or static friction !,well worth looking into.. As far as a fork goes ,yes it would be a wise move to a triple clamp Or double triple clamp as there correctly known ,for their upper stiffness is greatly increased,A couple of years ago I used a Manitou X-Vert R that had 115 mm of travel,they had compression damping,rebound damping,preload ,and the TPC,they held up real well for sport class DH and now they can be picked up at most places quite cheap !! . I hope this helps you . Cheers , - Buddy
