BMW Lightweight Aluminum Flywheel Upgrades for BMW 3 Series E92 (2007-2013)

Clear BMW chassis

hasmanufactured and supplied high quality lightweight aluminum flywheels to theperformance industry for over 25 years. JB is the original designer andmanufacturer of the BMW E36 aluminum flywheel. JB Racing is constantly expandingtheir flywheel line to include the latest performance applications such as; MiniCooper and BMW E46 325/330, and Z4 utilizing the new 6-speed (SMG) transmission. ALL of the current dual-mass replacement flywheels are designed to accommodatemost of the common sprung-hub clutch discs to minimize the gearbox “rattle.”Sachs, S.P.E.C., Clutch Net, and others manufacture sprung-hub discs that willclear in the center hub cavity of these flywheels.

All of their flywheels are designed, manufactured, and assembled in-house attheir  Florida facility which allows to maintain stringent quality control.You simply cannot buy a higher quality lightweight aluminum BMW flywheel… atany price!

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 youaEURtmll 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.

Our recommendations:

  • 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

Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, 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.

In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. Again, the difference is huge as you watch the revs build faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

The JB lightweight flywheel is designed to be used with a factory organic clutch - the same clutch kit that you would get from any BMW dealer. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches. By using the factory BMW clutch, JB has also made the whole assembly easy to live with when used on the street. The clutch behaves the same as it originally did - just with better throttle response and more power! The JB flywheel can also be rebuilt with a new clutch contact surface - you don't have to buy a new flywheel.

Aluminum flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch).

This JB flywheel replaces the stock flywheel and can be used with either the stock 228mm or stock 240mm clutch discs. Depending on the model you may have either clutch size in your car but this flywheel is compatible with both. You can install a 240mm clutch as a mild upgrade.

Stock Flywheel Weight = 24-31.0lbs
JB Flywheel Weight = 12.0lbs
