Find Parts That Fit Your Vehicle

BMW Drivetrain Parts

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

VTT noticed a hole in the A9X/Z4 market for a high-quality, lightweight, NVH-friendly, and easy-to-install Diff Lock Down kit to improve diff stability under launching, and hard cornering. Vargas went to work on a very innovative design that 100% positively locks the diff down from movement, while shielding it from adding a ton of NVH, and can be used with the stock diff, and subframe bushings. This design uses existing mounting points on the vehicle, you do NOT have to remove the subframe or the Diff to install. Simply remove 4 diff bolts, drill two holes in the subframe slightly bigger, install two M10 riv-nuts, and install the lockdown, you do not even have to move the exhaust. A typical install can be 15-30 minutes for someone who is experienced. You will need a Riv-nut tool to install the Riv-nuts as one is not included. Features: Lightweight 1.5 lbs for the entire lockdown plate Uses FOUR connection points on the Diff, and two on the subframe for the ultimate in positive diff location, this will stop all diff movement on launch, saving your guibos, etc 100% Billet construction from 6061-T6 aluminum Anodized in 4 colors for corrosion resistance, a long-lasting finish, and good looks The subframe does NOT have to be removed for installation Uses all 12.9 grade hardware Does not add excessive NVH Positively locks down the diff to eliminate all unwanted movement under launches, acceleration, cornering, etc.
