BMW Performance Clutch Kits & Parts for BMW Z Series E85/6 (2003-2008)

If you've ever bled the clutch hydraulic system on your BMW, you know how frustrating it can be. Designed with both DIY enthusiasts and professional technicians in mind, our clever tool simplifies one of the most notoriously annoying steps in clutch service.

Crafted from high-quality aluminum and finished in a durable black anodized coating, our clutch slave cylinder bleeder tool is built to last. Its function is simple: the adjustable piston rod applies controlled pressure directly to the clutch slave cylinder’s piston, compressing it and reducing its internal volume. By minimizing the amount of air trapped inside the cylinder, bleeding becomes faster, cleaner, and far more effective—no more endless pedal pumping or inconsistent clutch feel. The result is firm, consistent clutch pedal engagement and a smoother overall driving experience, all achieved with less time and effort underneath the car.

Adapt an N54 or N55 GS6-53BZ transmission to your M5x/S5x engine to unlock superior torque capacity and optimized gear ratios.

Engineered for the BMW enthusiast who demands more strength and better gear ratios, the Turner Motorsport Transmission Swap Flywheel Kit provides a direct solution for mating a modern N54 or N55 6-speed gearbox to your M20, M5X, or S5X engine. This kit bridges the gap between generations, allowing you to run a high-capacity GS6-53BZ transmission without the typical fabrication nightmares.

The technical core of this kit is our dual-geometry flywheel. By utilizing this specialized design, you can retain your engine-side stock starter while using the factory clutch and throw-out bearing from your donor transmission. This ensures a precise fit and a firm, factory-like shifting feel that can handle significantly more power than older 5-speed setups. To guarantee a fitment, we’ve included a precision drill guide for bellhousing alignment and a universal pilot bearing pin to simplify the installation process.

Features and benefits:

Compatible with the starter from your original motor.
Uses factory clutch and throwout bearing from the donor transmission (GS6-53BZ).
Comes with necessary tools and a provided drill guide to adapt the top transmission mounting holes.

Lightweight flywheels have proven themselves to be a worthwhile performance enhancement. But with the quicker throttle response and horsepower improvement comes one serious drawback: flywheel chatter. Without the dual-mass flywheel's rubber isolators, a lightweight aluminum flywheel has more rattle than stock. ECS has designed this flywheel using chrom-moly steel and it weighs almost ten pounds less than the stock DMF but not as extreme as full aluminum flywheels. The steel helps dampen vibration and noise so you get near-factory refinement and most of the benefits of a lightweight flywheel: quicker throttle response, better reliability, and more power to the wheels. This flywheel requires the E34 M5 sprung hub clutch kit.

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.

Stock flywheel weight - 25.0lbs
ECS flywheel weight = 16.55lbs

Why is SFI testing and certification important?

The SFI Foundation, Inc. (SFI) is a non-profit organization established to issue and administer standards for the quality assurance of specialty performance and racing equipment. SFI certification indicates a flywheel has been certified using industry-standard SFI Spec 1.1 standards by an independent testing body to ensure quality of both design and materials for flywheels utilized in competitive motorsports.

Having successfully passed SFI certification, this flywheel has an individual SFI serial number found in a laser etching, and on an affixed sticker. This certification means the ECS-engineered flywheel is safe and reliable during the rigors of competitive racing; it's also safe and reliable for years and years of street use.

Lightweight flywheel and upgraded clutch kit for improved throttle response, acceleration, and clutch feel - the perfect setup for daily-driven vehicles with up to 400 Ft/lbs of torque.

This performance clutch and flywheel kit utilizes an upgraded ECS E34 M5 clutch kit with their in-house engineered flywheel to fit all M5x and S5x motors with a 5-speed transmission. By eliminating the dual-mass flywheel and replacing it with a single-mass you are able to eliminate the slack and extra weight of the flywheel for a quicker throttle response and acceleration. Their upgraded clutch kit utilizes all the best features of the original M5 clutch with an upgraded pressure plate and clutch disc, with the new clutch you have a better, more engaged clutch pedal feel, engagement, and longevity.

Whether you're replacing a worn-out clutch or upgrading for increased power handling, this E34 M5 clutch and flywheel kit offers a reliable solution for enhanced pedal feel, power capacity, and overall driving satisfaction.

Paired with a modified geometry flywheel, the E34 M5 style clutch is ideally suited for most E36, E46, and others using the same powertrain. It checks all the boxes for essential clutch replacement features. While some aftermarket options may address slipping issues and worn-out clutches, they often sacrifice pedal feel, providing little to no resistance. A soft clutch not only kills the driving experience of your BMW but also reduces confidence when pushing the car to its limits.

On the contrary, you might be in the market for an upgraded clutch to handle your modified engine/forced induction builds. You go from an OE or aftermarket clutch option that has a lackluster and soft pedal feel to the complete opposite side of the spectrum, a very stiff clutch that grabs like an on-and-off switch making the clutch a pain almost undrivable on the street resulting in your favorite car turning into your least favorite car to drive.

The E34 M5 clutch and flywheel kit balances performance with practicality, ensuring a satisfying driving experience whether you're maintaining your BMW or preparing it for increased power demands.
