Made for both Team Associated RC8B3 and Mugen MBX7 are the AVID FastTune camber shims. The FastTune camber shims are made from Aluminum 6065-T6 anodized in black and designed to allow you to easily adjust your camber on popular pillow ball designs without having to fully unthread them. The tab feature helps you keep them in place as you tighten down the pillow ball. Don’t get caught up in all the complicated sizes AE has introduced, 0.5 and 1.0mm shims have been working for Mugen since the dawn of time. Also fits to other cars with 6mm threaded pillow balls.
