The Function7 E46 M3 Flex Disc Propshaft Coupling (guibo) is designed as a high performance replacement component for the OEM BMW rubber flex disc (BMW P/N 26112226527). It is designed from the ground up for motorsports use, and features long-life polyurethane flex bushings surrounded by a self-balancing floating cage, precision CNC machined out of billet aerospace-grade aluminum. We have also engineered our flex disc to be easily disassembled and rebuilt with regular hand tools if any of the components ever need replacing.

While improving on the shock absorption characteristics of the standard guibo, the Function7 flex disc does not compromise on performance or driver comfort, and does not impart any additional NVH (noise, vibration, & harshness) to the cabin. The replaceable polyurethane flex bushings also reduce the drivetrain shock to the vehicle's driveshaft and rear differential, buffering these components from the drivetrain vibrations and shock loads, reducing the wear and tear in the process.

The Function7 E46 M3 Flex Disc Driveshaft Coupling kit comes pre-assembled with high strength alloy fasteners, and is accompanied by a full set of high strength bolts and locknuts to quickly install the part onto the vehicle.
