This is an OEM LuK stock twin mass flywheel for the N52 non-turbo engine in the 128i, 325i/328i/330i, 525i/528i/530i, and Z4 30i. It's manufactured by OEM supplier LuK. Sachs recommends a new dual mass flywheel (DMF) on every other clutch replacement. There are several indicators for replacing the flywheel: damage to the clutch contact plate (from a severely worn clutch disc), grease leaking from inside (overheating), build-up of clutch material on the contact plate (excessive slipping and overheating), and failure of the internal damping system.

The dampening system uses rubber or coil springs to absorb driveline vibrations. Through age, excessive heat, and aggressive use the rubber loses its resilience and the metal springs lose their strength and become brittle. If the clutch and flywheel have become overheated the internal grease may break down as well. A DMF failure can be massive and catastrophic, not to mention dangerous as bits of metal and rubber fling themselves through the transmission bellhousing. Heat and aggressive driving will accelerate the wear so race and track cars should have their stock flywheels replaced at regular intervals or with any new clutch. Even normal street cars should plan for a new flywheel if it has high mileage.

OEM Schaeffler (INA, LuK, & FAG) is an engineering company that focuses on high-performance, precision manufacturing. With their individual brands INA, Luk, and FAG providing exceptionally high quality parts directly to BMW, as well as countless other automotive companies, their history of reliability and variety of offered parts makes Schaeffler a go-to replacement parts provider for all of us here at Turner Motorsport.

As a leading source of high performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts.  All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

DMF wear can only be checked with the transmission and clutch removed. If you can rotate the outer flywheel more than 20mm in either direction then it should be replaced.

A new pilot bearing (roller bearing) is included, pre-installed in the flywheel hub.

Working in collaboration with Competition Clutch, the up and coming German automotive performance company DKM has released a new line of high quality clutches made to satisfy your stock and modified performance needs! If you're having problems keeping power to the wheels, DKM has the solution. Their design, using high-grade materials, gives you increased strength and heat tolerance preventing wear and fade, ensuring increased torque capacity, quicker shifts, and a longer clutch life.

Tracking your vehicle is all fun and games until your start burning through clutches as fast as you can afford to replace them. To end this cycle, the MS Twin Disc Clutch Kit is designed to hold up to 100 to 200% more torque capacity and provide you with a much improved clutch life span. The two organic disc setup provides additional contact surface areas to more evenly distribute pressure and heat for both a boost in performance and wear prevention.

Kit Contents:
Pressure Plate
Two Organic Discs
Steel Single Mass Flywheel
Pilot Bearing/Bushing and Throw-out Bearing (when applicable)

The Pneumatic CV Boot Installer simplifies CV boot installation through air power. Its sturdy metal fingers stretch the boots, enabling effortless slipping over constant velocity joints without the need to remove them from the axle.

This efficient tool reduces the once time-consuming two-hour task to a mere 20-minute job, saving significant labor and effort. Operating it is a breeze?all you need is an air compressor, making it convenient for both professionals and enthusiasts in the automotive industry.

Crucially, it works exclusively with flexible CV boots, and is not compatible with plastic boots. With its user-friendly design, this installer is a game-changer in automotive maintenance, offering a hassle-free solution for CV boot installation.

Plus, our Air Powered CV Boot Installer comes with a LIFETIME REPLACEMENT guarantee, ensuring you never have to worry about spending hours on boot installations again!

This clutch package is designed for high HP vehicles desiring a start performance similar to O.E. The pressure plate is Race Engineered (SS) and SFI approved with significant load increase over stage 1,2 pressure plates (+600-800 lbs.). Expect a pedal effort increase of 20%-25%. Discs are assembled with heat-treated wear resistant hubs; drive plates and springs for high load transfer and dependable operation. The sprung centers on the disc in conjunction with the marcel fin between the linings create a dual dampening effect that simulates O.E. start performance. A Performance Organic friction material with a high metal content increases torque and RPM capability and maintains low operating temperatures which reduces wear and glazing.

Stage 3 Daily Clutch Kits:

Recommended usages are daily, spirited street and occasional track
Conservatively rated to hold 500lbs/ft of torque
Featuring a solid-hub center section for use with an OE dual-mass flywheel

The best way to gain a prominent advantage over the competition is to do it with the MFactory Helical Limited Slip Differential. The smooth consistent distribution of power to the wheels with the MFactory Helical LSD puts the power-to-the-ground and maximizes your vehicle's traction. A must for any car be it street, strip, or track.

What exactly does an LSD do you ask? Without an LSD your car is actually 1 wheel drive, in that it can't supply torque to both wheels at the same time and will only supply torque to the wheel with less grip, which is what the shortfall is to an open differential (what most vehicles have).

An LSD only lets the wheels spin at different speeds by a limited amount (typically this is a percentage difference) which is when the differential locks and both wheels get power. This is not how locked differentials work such as in off-road trucks which supply equal torque and rotational speed to both rear wheels at the same time, which can cause issues with handling.

Features:

An industry first, 30-day Feel the Torque™ money back guarantee and a Limited-Lifetime Warranty!
Forged and Cryo-tempered
Advanced Shot Peening technology for increased surface hardness
Designed to withstand the extreme shock loads of competition-level drag racing
Maintenance-free gears eliminate the need for special fluid or rebuilds associated with typical plate LSDs.
Lock-free operation ensures no adverse steering response.
**As a break-in procedure, we recommend changing the fluid after the first 3-400 miles of use.**

Includes $500 core charge to be refunded when we receive your rebuildable core.
