PMC Motorsport clutch kit for BMW N54 N54B30 (6-mounting bolts) GS6-53BZ 6-speed 240mm / 9.45" + Sachs XTend 3000 951 952 max. 650Nm / 479.25lb⋅ft

Planning to increase power in your BMW E8X 135i E9X 335i [BMW N54B30 (6-mounting bolts)]? This kit is for you! Complete clutch kit, rigid / light aluminum flywheel, and Sachs XTend 3000 951 952 (pressure plate, organic clutch disc, and release module).

The lower inertia of a lightweight flywheel results in much better and faster throttle response, improving the car's acceleration. Although engine power does not increase, drivetrain losses are reduced, translating to slightly higher power at the wheels. Lightweight flywheels perform excellently on twisty tracks, as the car regains lost speed much faster after corners.

Applications:

• Drift / Time Attack: Where precise control over engine RPM and rapid reduction of unsprung mass are crucial.
• Street Tuning: For enthusiasts who want to eliminate the failure-prone dual-mass flywheel and experience a sportier character of their car.
• Motorsport: Wherever every second and every kilogram of weight reduction matters for the final result.

Advantages of a lightweight flywheel:

• Instant throttle response: Reducing rotating mass allows the engine to rev up much faster, improving dynamics during gear changes and overtaking.
• Increased durability in sports: Made from the highest quality aerospace aluminum alloy, the wheel is resistant to extreme temperatures and loads that could damage a factory dual-mass flywheel.
• Serviceability (Replaceable surface): Thanks to the replaceable steel friction surface, the wheel is a solution for years – when worn, you only replace the insert, not the entire element.
• Ease of installation (Bolt-on): Designed for factory mounting points, ensuring full compatibility with the stock pressure plate and starter without modifications.

Weight

When designing our flywheels, we pay great attention to their weight – PMC flywheels are created for both tuning enthusiasts and motorsport builders, which is why choosing the right mass is so important.

Inertia vs. Acceleration

A flywheel stores kinetic energy. The heavier it is, the more energy is needed to set it in motion.

• Too light: The engine revs up instantly, which is desirable in sports, but drops just as quickly. This can make smooth gear changes difficult in daily use.
• Correctly balanced: Allows for faster throttle response while retaining enough energy for the engine to operate properly after releasing the accelerator pedal.

Idle Stability

A lightweight flywheel has a lower capacity to dampen engine irregularities (especially in 3- or 4-cylinder units).

• If the weight is too low, the engine may idle roughly, jerk, or even stall during sudden declutching (e.g., when approaching lights).
• Appropriate mass provides an "inertia buffer" that maintains crankshaft rotation between the power strokes of individual pistons.

Ease of Starting (Torque)

A heavy flywheel helps "move" the mass of the entire vehicle from a standstill.

• With an extremely light wheel, the driver must apply much more throttle and operate the clutch more precisely to avoid stalling.
• Proper weight selection allows the car to maintain its civilized character, enabling smooth starts on hills or in traffic.

Specification

!! 55.7% Lighter than the OE flywheel !! Only 7.07kg / 15.59lb which is approx. 5.95kg / 13.12lb less than the factory wheel.

• Compatibility: PMC custom flywheels are designed to work with OE BMW clutch kits or replacements fitting the OE flywheel.
• Clutch Disc: Designed for use with factory clutch discs compatible with your gearbox.
• Replaceable friction surface: The friction surface ensures durability. It is easy to disassemble, and replacement parts are available in our offer.
• Original starter ring gear: Galvanized ring gear with identical hardness to OE flywheels, ensuring reliability and full cooperation with the OE starter.
• Balanced before shipping: Every PMC flywheel is checked and precisely balanced before shipping. If using a used or custom clutch kit, we recommend rebalancing the entire set.

Please note that a lightweight flywheel provides uncompromising throttle response at the cost of eliminating factory damping elements. This translates into more direct drivetrain operation, which may result in a natural increase in gearbox noise. This is a desired characteristic in sports vehicles.
