Vibra Technics E46 M3 S54 6-Speed Manual (6MT) Gearbox Carrier/Crossmember & Transmission Mount | Gearbox Support Bar, Shifter Stabiliser | Replaces BMW 22312229198 | Fast Road & Track

Unlock tighter gear changes and rock solid driveline control on your E46 M3 6 speed manual. This Vibra Technics gearbox carrier replaces the flimsy factory bracket and soft rubber mounts with a one piece support that incorporates high stiffness isolation elements. Expect a stable transmission, consistent shift linkage alignment and confidence on fast road and track without a big increase in noise, vibration or harshness.

If you are chasing precise shifts, reduced shifter wander under load and better propshaft alignment, this upgrade is the smart choice. It is engineered to stop excessive movement that leads to missed gears, driveline knock and premature wear of surrounding components. A robust, fail safe architecture keeps the unit secure even under heavy cornering, acceleration and braking.
