Suites 5 speed and 6 speed transmissions
(Center bearing can simply be removed for use with gearboxes that require the spigot bearing in the crank)

Made from High tensile Chrome-molly steel these flywheels are both light and very strong.

Weighing only 4.4Kg (9.7Lb) they will greatly increase the response and acceleration of any vehicle

CLUTCH
Almost all BMW engines 4cyl, 6cyl and even some 8cyl have the same clutch fitment from the years about 2000 right up to 2020 and possibly beyond. There are a great number of clutches that will fit with this FW and there are great options for stronger clamping force  if required by selecting clutches from oem turbo or v8 vehicles.

FW does not come with bolts. OEM bolts can be reused but the DMF bolts will be too long, OEM bolts for almost all models of BMW cars with Automatic transmissions will fit perfectly (m12x28)

Myth Buster!!........

It is a common perception that a large flywheel is used to increase the torque of and engine and with a light flywheel an engine will have less torque but this is NOT the case! Heavy flywheels are used only to ease the smooth engagement of the clutch so Grandma can take off without stalling the engine and that's it! maybe improve idle quality a little also. Once the car is rolling and the clutch is fully engaged the flywheel becomes completely unnecessary because the entire vehicle and its drive line becomes the flywheel storing huge amounts of momentum. Any additional weight particularly on the crank shaft only reduces the vehicles ability to accelerate briskly. So if Grandma isnt going to drive your car and you don't mind having to use a little more finesse with the clutch pedal then you will enjoy all the benefits of having a responsive engine with much improved acceleration. Even if its only a daily driven road car. We have many satisfied customers driving around on these flywheels every day just find and ask someone and they will be happy to report that drivability is not compromised at all, but the improved response and acceleration is very pronounced!
