HB Racing have introduced a new wide C arm mount for the D819, D817, D817T, E819, E817, D815 and D812. Machined from high-quality aluminum, it comes black anodized for wear. The C arm mount is wider and allows racers to run less than 2 degrees of toe-in. It can be used with D mounts with less than 3 degrees of toe-in to ensure proper fitment of the drive shafts. HB’s Team drivers report that it helps rotation and corner speed.
