PMC Motorsport Lightweight Billet Flywheel (SMF) - BMW N54 N54B30 135i 335i 35i (6-mounting bolts) - [N54 / 240mm / 7,07kg]
Upgrade your engine performance with the PMC Motorsport lightweight rigid flywheel for BMW N54 N54B30 (6-mounting bolts) engines. Precision-engineered using CNC-machined aluminum, this flywheel features a replaceable steel friction plate for extended durability. All mounting points are 100% compatible with the original OE flywheel for a perfect bolt-on fit.
Why choose a lightweight flywheel? Reducing the rotational mass (inertia) leads to significantly faster throttle response and improved vehicle acceleration. While it doesn't increase raw engine power, it minimizes drivetrain losses, delivering more power directly to the wheels. This is an essential upgrade for track days and racing, allowing the car to recover speed much quicker coming out of corners.

Note for Enthusiasts: A lightweight flywheel provides uncompromising performance and engine response by removing factory harmonic dampening. This results in a more mechanical feel and more direct power delivery. Please be aware that this can naturally increase the noise from the gearbox (gear rattle), which is a normal characteristic of performance-oriented rigid flywheels.
