The Avid RC -2° C Arm Mount for the AE 3 Gear Transmission is a must-have upgrade for high-bite surfaces like carpet and turf. Originally developed for the B6.3, this proven design carries over to the B7 platform to help free up the car without sacrificing rear track width.
Normally, achieving low rear toe on carpet means narrowing pills at the D mount—adding side bite and tightening the car too much. This C Arm Mount widens the C pivot block, allowing you to start at 1° of rear toe with centered pills in both the C and D mounts instead of 3°. The result is a freer, more predictable car that rotates better and handles awkward landings with confidence.
