Associated have released a number of new parts for the RC8 line of vehicles. First up are these lightweight drive train parts which have been machined to reduce weight to help the performance of the car. The parts getting this treatment are the diff ring gear and the 44T spur gear. Also new are these precision-machined, tapered Delrin pistons for the 16mm Big Bore shocks. The team set out to improve over the 10 x 1.1 piston setup with damping characteristics that also excelled when the track got bumpy. Extensive testing showed that by drilling out 5 of the 10 holes larger, the damping provided the best of both worlds. The larger 1.2mm or 1.3mm allow for better low speed damping over bumps, while still keeping the great smooth track handling characteristics of the smaller 1.1 hole setups.
