It's design is aimed at dampening drivetrain vibrations, smoothing gear changes, and ensuring a driving experience that is on par with BMWs line of luxury vehicles. An unfortunate byproduct of this design is the rotational mass it introduces to the drivetrain—a hefty 27 lbs! This added inertia hinders throttle response, making it difficult to rev-match and perform efficient gear changes. Moreover, dual-mass flywheels are a known weak point in modified applications and can prove expensive to replace.\u003c\/p\u003e\n\u003cp\u003eThe Turner Motorsport Single-Mass Lightweight Flywheel Conversion for BMW S65 addresses all of these shortcomings with a purpose-built, lightweight, single-mass design that prioritizes performance.
