Overview

The Turner Motorsport Performance Lightweight Flywheel is a single-mass flywheel designed for N54 powered BMW vehicles. It offers reduced inertia for quicker throttle response and improved acceleration compared to the stock dual mass flywheel.
Show original supplier description
The Turner Motorsport Performance Lightweight Flywheel is engineered to provide a balance of comfort, smoothness, durability, and performance for N54 powered BMW vehicles. Weighing 18.6 lbs, it is 10 lbs lighter than the factory BMW flywheel, significantly reducing inertia for quicker throttle response, improved rev-matching, and faster acceleration. Precision machined from 4140 HT heat-treated, stress-relieved chromoly steel, this flywheel features a 8620 steel pilot bearing for maximum wear resistance. It is black oxide coated for corrosion resistance on non-friction surfaces and is SFI 1.1 certified, ensuring safe operation under extreme conditions by passing rigorous third-party lab tests. This single-mass flywheel is designed to work with N54 architecture clutches. Audible chatter from the transmission after installation is considered normal, as single-mass flywheels have less dampening than dual-mass units. This noise may be more present when transmission fluid temperatures are higher and can be intensified by other modifications, but it will disappear when the clutch pedal is depressed. Fitment is specific: this flywheel is for vehicles with an 8-bolt flywheel and a build date up to 01/2009 or earlier. It is compatible with various BMW models including the 135i, 335i, 335is, 535i, and Z4 sDrive35i/is, all equipped with the N54 3.0L engine.
