The SPEC Stage 2 clutch is a premium, no compromises heavy-duty clutch upgrade for the 1996-1999 E36 M3. Where the stock clutch is well-known for premature wear when driven hard and the factory dual mass flywheel is a known failure point, the SPEC clutch delivers with an over-engineered, performance-oriented clutch solution. The single carbon-Kevlar clutch is rated at 370 ft-lbs, more than enough for the naturally-aspirated S52 engines. A heavy-duty pressure plate and throw-out bearing complete the package.

The stock clutch in the S52 cars is not a terrible clutch and it is not under-rated (it was the same clutch used in the Euro M3). Our tuned M3 street and race cars have used the stock clutch with over 300hp with only the occassional slip. But if the clutch is not grabbing like you want it to, or your tuning plans will include forced induction like our Project E36 M3, a heavy-duty clutch is what will be needed. The SPEC Stage 2 clutch consists of a carbon-Kevlar friction material paired with a heavy-duty pressure plate. The clutch is stronger and grabs harder than the factory clutch. It has a much more robust feel and engagement. And with this specification the clutch will never be a weak point. The SPEC clutch is designed to work with the stock dual mass flywheel or with a lightweight aluminum single-mass flywheel.

The real weak point in the driveline is in the flywheel. The stock dual-mass flywheel has rubber damper discs inside that will wear out over time. Heat and aggressive driving will accelerate their wear. Even if the clutch contact surface is not showing wear the inner rubber linings most likely are. On most clutch replacements we strongly advise getting a new flywheel at the same time to avoid duplicating the work. You can use the SPEC clutch with the stock or aluminum flywheel. A machined steel flywheel is also an option as a middle ground. Both the SPEC steel and aluminum flywheels are lighter than stock and will be single-mass. There will be a lot more noise and 'gearbox chatter' with the aluminum but the tradeoff is a much better acceleration and quicker revving. For daily driver commuting you will probably be happiest with the stock flywheel. For the ultimate in sports car feel use the aluminum.

SPEC Clutch is one of the premier clutch and flywheel suppliers to the tuner market. They are often found on the most highly tuned import and domestic vehicles. They are recent players in the German car community with a special focus on the newer turbo BMW models with high torque output. SPEC has been proven time after time to provide superior performance, drivability, and longevity to the most hardcare enthusiasts around the globe.

The SPEC Stage 3 clutch is designed for tuned street or race/track cars that require a serious and capable clutch. The Stage 3 uses a semi-metallic and carbon clutch for strong engagement and high torque capacity (it's rated for 425 ft-lbs). Stage 3 is the same as Stage 4 but with double-sprung clutch for a smoother and quieter engagement. It's a more street-friendly version of the Stage 4 and popular among the turbo E30 crowd.

The stock clutch in the M20 E30 is not terrible but can become quickly overheated and lead to glazing on the flywheel surface and inconsistent engagement. A more robust material is needed to handle the extreme temperatures found at the track. The SPEC Stage 3 clutch consists of a carbon/semi-metallic friction material paired with a heavy-duty pressure plate. The clutch is stronger and grabs harder than the factory clutch. It has a much more robust feel and engagement. And with this specification the clutch will never be a weak point. The clutch is rebuildable to help minimize consumable costs. The SPEC clutch is designed to work with the stock dual mass flywheel or the SPEC single-mass aluminum flywheel.

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)

The SPEC Stage 3+ clutch has been engineered to stay in step with the above average upgrades done on the 135/335/535/Z4 35i. Everyone knows that adding large amounts of boost and torque will expose weaknesses in other areas - the clutch being near the top of the list. The factory clutch works just fine on a stock 335 or with a mild upgrade like software and intake. But when you get into serious torque levels the stock clutch simply can't handle it. SPEC has focused heavily on the 335 market with 5 stages of upgraded 335 clutches. Stage 2+ is our favorite for mildly-tuned 335s, offering near stock levels of refinement and ample torque capacity (rated for 545ft-lbs). But when going beyond the usual bolt-on upgrades you need to look at your weakest links. The Stage 3+ clutch is rated for 671 ft-lbs. This clutch kit is meant to be used only with a SPEC flywheel (not the stock flywheel).

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. See comments below for characteristics of each.

The Stage 3+ can be configured a few different ways depending on how you intend to use the car -

#SB533F-2 Variant	Use	Comments
"Sport" SPEC steel flywheel	daily driving; occassional drag strip	Use this with the SPEC steel single-mass flywheel. The clutch will be stiffer than the factory design but it will grab harder and stay connected with far less chance of slippage. The engagement point is changed but most drivers adjust within the first 100 miles. The failure-prone dual-mass flywheel is eliminated and a steel single-mass is used instead. Expect more noise and vibration from the steel but better reliability and slightly better performance.
"Super Sport" SPEC aluminum flywheel	more drag strip than street	Use this with the SPEC aluminum single-mass flywheel. The clutch will be stiffer than the factory design but it will grab harder and stay connected with far less chance of slippage. The engagement point is changed but most drivers adjust within the first 100 miles. The failure-prone dual-mass flywheel is eliminated and a lightweight aluminum single-mass is used instead. Expect a lot more noise and vibration with aluminum ("gearbox rattle") but better reliability and better performance. The engine will rev a lot faster too.
