These mounts are designed for a 1983-1991 E30 BMW 3-series with a 24
valve M50/M52/S50/S52 engine swap with an E21 brake booster. They use the oem motor mount bolt
holes on the E30 subframe. The mounts are angled with offset bolts to
position the engine so that proper drivetrain alignment is maintained. They are used with E36 engine brackets.
