DRIVE FACE BOSS

Variable tuning set for original variators and almost all tuning variators.

The Speed-up shims can influence the length of the sleeve: an extension usually improves the acceleration and shortening increases the top speed.

Kit contains the open racing variator sleeve and 30 spacers, each with 10 discs with 0.1, 0.2 and 0.5mm thicknesses.
