Bavarian Autosport Guibos and Flex Discs for BMW Z Series E85/6 (2003-2008)

Clear BMW chassis

Find BMW driveshaft and axle shaft parts, including flex discs (aka: the guibo) is a vibration dampener mounted on the back of the transmission. The flex disc acts as a buffer between the transmission's output shaft and the driveshaft leading back to the car's differential. Visual inspection is the only way to tell if the disc is beginning to wear. Cars with worn discs will notice a harsh vibration when starting from a stop and the disc should be replaced (along with the center support bearing) ASAP.

This replacement flex disc (aka: the guibo) is a vibration dampener mounted on the back of the transmission which connects to the driveshaft. When it has worn, it produces a terrible vibration throughout the car. It's especially noticeable at low speeds and when starting from a standstill. Oil leaking from the back of the transmission will significantly reduce its life. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

This Bav Auto replacement flex disc (aka: the guibo) is a vibration dampener mounted on the back of the transmission which connects to the driveshaft. When it has worn, it can produce knocking sounds and a terrible vibration throughout the car. It's especially noticeable at low speeds and when starting from a standstill. Oil leaking from the back of the transmission will significantly reduce its life. This can also be used as an upgrade on the E30 M3. It has much more rubber in between the bolt holes which makes it last longer. This is 5mm thicker than the stock E30 flex disc so adjustment of the 2-piece driveshaft may be required. The original flex disc bolts can be re-used.
