This is the large 96mm race flex disc (Guibo) with 12mm bolt holes. It is commonly found on the E30, E36, and E46 M3, as well as a wide range of other vehicles. Please refer to the cross reference links below.
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.
Note: 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.
