BMW Lightweight Performance Flywheel M50 M52 M54 S50 S52 S54 Heavy Duty

Description

BMW Lightweight Chrome-Molly Flywheel

This is a heavy Duty version of our popular m4x m5x S5x series flywheel. This is also Hybrid product and takes the the big strong 240mm M30 series clutch!

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

Weighing only about 3.8Kg (8.5Lb) they will greatly increase the response and acceleration of any vehicle. Clutch weight is still a significant addition so there is no possibility of being "too light"

Clutch fitment is standard 240mm from BMW M30/m88/S38 Engines  These clutches are very strong with fully sprung centers. They are ideal for use with single mass FW giving a really nice smooth OEM feel while still being capable of transmitting a large torque capacity!

It will fit in all the e36 gearboxes both 4cyl and 6cyl including the 220 (G250) and also the m20 G260 gearbox.

NOTE! this FW and clutch combination will not fit in bell-housing of the g240 e30 4cyl gearbox,

There are a few different grades of OEM clutch kits commonly available for this Flywheel. here are just 2 examples. Note that clutches for m30 Duel Mass FW are NOT compatible

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 thats 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 driveline becomes the flywheel storing huge amounts of momentum. Any additional weight particularly on the crank shaft because this spins at higher speeds only reduces the vehicles capability 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 to take off from the lights then you will enjoy all the benefits of having a snappy responsive engine with much improved acceleration that comes with installing a light flywheel, even if its only a daily driven road car! We have many happy 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!
