The Stage 3+ is for cars making serious levels of boost and torque. If you have upgraded turbos or a single-turbo conversion, or have checked off the list of full bolt-ons, this will be a very capable clutch for you. This clutch is designed to work only with a SPEC single-mass flywheel and avoid the pitfalls of the stock OEM flywheel. The stock dual mass flywheel uses springs and rubber to isolate vibrations from the engine and transmission. However, on high mileage or abused flywheels the rubber can break down and the springs will become weak. A worn dual mass flywheel limits the amount of torque you can put out. It will affect clutch engagement, shifts, and power delivery. In some cases a total flywheel failure can rip apart the flywheel, clutch, and even transmission housing. With the SPEC single-mass flywheel the limitations of the stock flywheel are eliminated. The SPEC flywheel is a single mass design (no internal springs or rubber to fail) and is offered in a steel or aluminum material. The steel will better dampen vibration than the aluminum so it's the better choice for street use. The aluminum will have greater vibration and noise (gearbox rattle) that may not be acceptable for everyone. The clutch in this Stage 3+ kit is a sprung hub design so SPEC has done all they can to minimize the noise and vibration. It's also self-adjusting, like the factory design, and the engagement point can be adjusted. For use with SPEC Billet Flywheel (E-Chassis cars) or (F-Chassis cars)

Tuning your N54/N55 with all of the bolt-on upgrades? Don't allow your clutch or flywheel let you down! The stock clutch is fine for a stock car or just a simple software upgrade. But anything more and it quickly becomes the weak link (especially with drag races or hard launches). The 135i/335i/535i/Z4 35i SPEC Stage 2+ clutch kit is perfect for owners who want a performance clutch that works great with simple bolt-on modifications and will have a minimum of downsides or trade-offs. SPEC has spent considerable time and effort on the 335i models to produce a performance clutch and flywheel package that holds up to track and drag strip demands but is also easy to live with for daily driving. This clutch kit is meant to be used only with a SPEC flywheel. Features: The flywheel has a peak torque rating of 545ft-lbs Limitations of the stock flywheel are eliminated Self-adjusting, like the factory design, and the engagement point can be adjusted Sprung hub clutch to be used with the single-mass flywheel with near-stock levels of noise, vibration, and refinement **Due to the nature of lightened single mass flywheels added "NVH" or "chatter" will or may occur during operation. Accompanying modifications can also increase or decrease the amount of "NVH" or "chatter" in the drivetrain. Please contact our sales team with any questions.**
