Schelle B6 2mm carbon fibre gearbox shims
Schelle Racing Innovations’ 2mm carbon fibre gearbox shim set helps to raise the gearbox of the Team Associated B6 when racing on high-grip carpet or astro turf. Doing so will reduce driveshaft angles, making them more level, which results in an easier to drive car on high-grip surfaces. The set includes four 2mm shims that raise the laydown gearbox and Schelle recommend to use their laydown motor plate to lower the motor back down to the chassis while also using long shock ends for 2mm of added shock droop.
