E30 Brakes
BMW E30 brake rotors can be fitted to the 1200 hub. These are large 260mm vented discs.
Overview
The rotor height is only 1/2 mm taller. Machining of the bolt holes is required, as is a custom fabricated caliper bracket (to space the caliper up farther). For a similar swap which requires no machining, see S13 Brakes.
