BMW Performance Clutch Kits & Parts for BMW 3 Series E92 (2007-2013)

Engineered in-house, we designed this lightweight, single-mass flywheel to provide more than 10 pounds of weight savings over the factory flywheel. While some ultra-lightweight performance flywheels are manufactured from aluminum, our designers opted for a more driveable experience with steel. The mass provided by steel helps dampen vibrations and noise, delivering near-factory refinement with most of the benefits of a lightweight flywheel: quicker throttle response, improved durability (and longevity), and more effective transfer of power to the wheels. 

Modern flywheels are built with additional components that are designed to dampen and minimize vibrations from the engine and transmission. Weight has increased and reliability has decreased. With additional weight more energy is required for it to move. A lightweight flywheel does away with the dual mass design and its additional mass so more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance. And with a single-mass flywheel the unreliable DMF design is eliminated.

When it comes to selecting a clutch to pair with a lightweight flywheel, consider the driving you’ll be doing. As a single mass flywheel eliminates the dual-mass dampening of the factory flywheel, to retain the lowest noise, lowest harshness driving experience possible, select a clutch with a dampened disc. For dedicated track cars, a solid clutch hub is appropriate.

• Street: ACT Heavy Duty 
• Track: ACT Xtreme for high torque cars or OE 335is LuK (with 440lbs-ft or less)

Features:

• Precision machined from 4140 HT heat treated chromoly steel for exceptional toughness, even wear properties, and durability.
  • Material quality promotes even wear across the entire friction surface
  • Heat treated to HRC 28-32, tempered to relieve stress and improve dimensional stability and elevated temperatures
  • Hardness improves wear characteristics
• Black oxide coated for corrosion resistance on non-friction surfaces.
• 8620 steel pilot bearing pin, case hardened and Precision ground for maximum wear resistance.
• Precision balanced to exceed OEM specification (G16 spec to 175g-mm).
• SFI 1.1 tested and certified to ensure safe operation under extreme operating conditions
  • SFI 1.1 specifies minimum material properties and requires a 3rd party lab certification test, spinning the flywheel to 1.5x redline for 1 hour to ensure the flywheel will not burst.
• Specifically designed to work with N54 architecture clutches
• Step height designed to optimize clamp load and maximize the usable range of clutch wear for a long service life

Performance:

• Turner Flywheel 18.6 lbs
• 10 lbs lighter than the factory BMW flywheel (Stock Flywheel 28.9 lbs)
• Faster revs
• Improved throttle response
• Improved acceleration
• Sportier driving experience

Stock flywheel weight - 28.9lbs
Turner single mass flywheel weight = 18.55lbs

Genuine BMW Clutch Kit for your 6 Speed Manual Transmission vehicle - 
This item fits the following BMW Chassis:
E92,E93,F10,F12,F13

This is the stock OE BMW twin mass flywheel for the N54 engine in later E82 135i, E9X 335i, E60 535i, and Z4 35i (cars with 6-bolt mounting hub). 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.

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.
