Lightweight flywheel for quicker, effortless revs that improve throttle response and free up lost horsepower. Tested and approved by our engineering team at Turner Motorsport. Tested in early, late, ETA and IS model E30s for confirmed fitment.

Introducing our Turner Flywheel: an ingenious blend of lightweight design, rich features, and remarkable strength! Crafted from 4140 HT Steel, this flywheel is precision-machined from a solid piece, ensuring unmatched durability. By strategically trimming excess weight from its original design, we've achieved a significant reduction in weight, giving new life to your M20 engine. With upgraded efficiency, your M20 can now swiftly spin to high RPMs, unleashing the full power and prowess of this formidable engine. Our flywheel features a ring gear profile compatible with all starters, alongside a reference tab tailored for early cars equipped with bellhousing-mounted sensor crank position detection.

Do you have an early model transmission with the crank sensors on the bellhousing? Maybe you have a late 325is with the crank sensor on the front of the engine, or maybe you have a 1988 super ETA. No matter which E30 model you have, our flywheel is the perfect choice for you.

During the engineering process we encountered the full spectrum of M20 and flywheel combinations. Early cars with bellhousing crank sensors, late cars with front mounting crank sensors and even a super ETA. On this adventure we found both early and late single mass flywheels and even the dual mass that we thought for sure was just a myth. At first we were hesitant that we could make one flywheel to fit them all but with the persistence of our engineering team(fleet of E30 enthusiasts) we can proudly say our M20 flywheel does in fact fit all engine and transmission applications you can think of.
