RC Carbon Cavalieri have introduced the all new 5mm carbon fibre spacer for the HB Racing D819 and D817. The part is machined from high-quality carbon fibre and allows to be use in 3 ways. The spacer allows to move the rear wing 5mm backwards to improve the downforce, to move the rear shock tower to improve dampening and also line up the camber links. All these update improves the rear stability on rough surface tracks, during acceleration and on jumps.
