BMW Drivetrain Parts for BMW 3 Series E30 (1984-1991)

Vague or slopping shifter feel even after installing a short shifter or new OE shifter linkage bushings?  Looking for a more precise shifter feel in your classic BMW?  Consider replacing your old, worn rubber rear shifter bushing with new Turner poly to get the best shifting experience possible!  The Turner engineering team wasn’t satisfied with the other options on the market, so we set out to design the best solution for ease of installation and performance.

The competition requires the installer to cut or burn the rubber bushing out of the stock housing to be able to install their poly bushing, requiring reuse of an old worn out housing, or buying a new costly bushing assembly.  We decided this was cumbersome and unnecessary, so we designed a complete upgrade replacement bracket with a 70A polyurethane bushing preinstalled for a quick bolt-in installation.  Our bracket is precision formed with a CNC machined and TIG welded bushing cup to perfectly match the OEM bracket, and is made from 304 stainless steel for exceptional corrosion resistance.  The result is a complete design solution that creates much crisper shifting with nearly zero added NVH for a more engaging and enjoyable driving experience.

Note: Some shifter arms have a mushroom-shaped end. Use extra care installing our bushing on these arms. Filing this mushroom down makes installation easier, however simply applying sufficient pressure to the back side of the bushing during installation will allow this bushing to install smoothly.

This is the last bushing you will ever want or need for your E28, E30, or E34!

Product Features:

• Pre-installed bushing, NO cutting or burning for installation
• Corrosion resistant 304 stainless steel mounting bracket
• 70A durometer poly bushing for reduced NVH
• Ready to install out of the box
• Replaces Genuine BMW part number 25111220707

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.

Features and benefits:

Fits early and late models with M20
Fits shallow and deep bellhousing transmissions
Ring gear suited for both starters (P# 12411726504 + 12411361874)
Heavier than other lightweight flywheels, lighter than OEM, its like the Goldie Locks of flywheels - its just right
Reference pin for bellhousing crank sensor
Strong Single-Piece 4140 HT Steel construction
Designed to be used with factory and OE clutches
