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 with type III hard anodizing 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.
