Components Overview

The kit contains a forged variator face finished in rainbow titanium, plus a movable rear variator face with red friction pad inserts. A polished aluminum sliding sheave, carrying the Top Racing brand, is included for smooth movement. The kit also includes a white contra spring rated 12% stiffer than the original, which is intended to sharpen throttle response during acceleration.

Weight Configuration and Adjustment

Nine roller weights come in staggered sets of 7g, 8g, and 9g. For correct operation, install them in alternating order around the variator's ramp slots.
