BFI Transmission Mounts - Stage 1 - BMW E30 / E36 / E46 / E9X / Z3 / Z4

Product Details

Factory BMW transmission mounts are designed for maximum isolation, but they often perish under the torque of spirited driving. Our Stage 1 mounts are engineered to provide a structural upgrade that won't crack or collapse like OEM rubber. This kit is a "must-have" for any E36, E46, or E9X owner looking to tighten up their drivetrain's foundation and ensure long-term mechanical reliability.

Key Features:

• Drivetrain Alignment: Maintains the critical angle between the transmission output shaft and the driveshaft guibo (flex disc).

• Guibo Longevity: By limiting transmission "wobble," these mounts actually extend the life of your expensive rubber guibo and center support bearing.

• Oil & Solvent Resistant: Polyurethane construction won't degrade if exposed to common transmission fluid leaks or road grime.

• Bolt-On Simplicity: Direct replacement for BMW Part # 23711175939 and 23711175424.
