Clear BMW chassis

Please ensure your correct model is selected

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.

Engineered in-house, our torque plate is designed to provide a robust and uniform clamping surface between the flywheel and crankshaft across a range of BMW engine applications. Compatible with both factory and Turner performance flywheels, it helps prevent surface galling and ensures consistent torque distribution during installation.

Prevents galling and wear at the crankshaft-to-flywheel interface under high clamping loads
Promotes even load distribution for improved fastener integrity and long-term reliability
Compatible with a variety of BMW flywheel setups, including OEM and aftermarket configurations
Design:

Precision-machined from cold rolled steel for high strength and dimensional accuracy
Heat treated to 32 HRC for increased surface hardness and wear resistance
Clear zinc anodized for enhanced corrosion protection
Laser-etched Turner logo
Ideal for performance builds and drivetrain refreshes, this torque plate is a critical component for maintaining proper flywheel installation and maximizing long-term durability across multiple BMW platforms.
