Description

BMW Race Flex Disc

Upgrade your drivetrain with the NS Custom Parts BMW Race Flex Disc, engineered for drivers who demand maximum durability, precise power transfer and improved drivetrain response.

Unlike the factory rubber flex disc, which deteriorates over time and allows excessive drivetrain movement, our design combines a CNC-machined billet aluminum housing with a high-performance polyurethane insert. This construction significantly reduces drivetrain deflection while still providing controlled vibration damping.

The result is faster throttle response, improved shifting feel and more direct power delivery, making it ideal for both performance street cars and dedicated track builds.

Each flex disc is CNC machined from high-quality aluminum and assembled using premium polyurethane for long service life, even under extreme driving conditions.
