These studs and spacers mount the E30 differential 12mm from the subframe. They are intended to be used with our 12mm offset subframe bushings. When raising the subframe, the spacers allow the differential to mount in the stock location which maintains proper pinion angle. The studs keep the spacers in place making for a quick and easy installation.
The spacers are made from 6061 aluminum. The class 12.9 studs have hex key reliefs. We recommend using loctite during installation. Flange nuts are included.
