FOR RACE USE ONLY!
This flex disc is for a 1983-1991 E30 BMW 3-series with an M50/M52/S50/S52 engine swap. It adapts the 96mm/12mm ZF transmission flange to the 78mm/10mm E30 driveshaft. It allows you to retain the oem 325i driveshaft when doing a 24v engine and ZF transmission swap. (Not compatible with the 4-cylinder driveshaft)
The Revshift race flex disc frame is made from 6061 aluminum and utilizes high quality polyurethane bushings to maximize stiffness and strength while maintaining an appropriate amount of flex.
FOR RACE USE ONLY! This part is very rigid and requires precise installation. The driveline must be properly aligned and all driveline components must be in good condition and properly balanced. The engine mounts, trans mounts, differential bushings, and subframe bushings must all be rigid to prevent driveline movement. We recommend a hardness of 95a or higher for these components. A new center support bearing and driveshaft centering bushing are also recommended. Some clearancing on the output flange may be necessary to clear the driveshaft bolts.
