BMW Performance Clutch Kits & Parts for BMW 1 Series E82 (2008-2013)

Clear BMW chassis
These heavy-duty clutch kits use aluminum lightweight flywheels with sport clutch components to give your clutch the grip and clamping force it needs to cope with high torque upgrades. Our kits were developed through racing programs by companies affiliated with our own race team - JB Racing, Sachs Sport, OS Giken, and UUC Motorwerks. JB Racing is the leader in aluminum lightweight flywheel upgrades. They are direct replacements for the stock dual-mass flywheels with steel contact surfaces and computer balanced to 14,000 RPM. JB has partnered with Sachs to spec sport/HD clutch discs and pressure plates that work seamlessly with their aluminum flywheels. The result is a clutch/flywheel upgrade package that functions a lot like the original clutch combo with near-stock levels of effort and engangement but with a much higher torque capacity. Don't let the clutch be your weak link in a highly tuned car!

This brass clutch pivot pin is an upgrade over the stock plastic pivot pin. The brass pin will last a lot longer than the plastic piece and may save you time and hassle later on. The original plastic pivot pin is known to fall out, snap, or just wear out over time. At the least you get a very annoying squeak every time you depress the clutch. In a worse case scenario, the clutch fork won't be able to push on the throw-out bearing and your clutch will be useless. The only time to replace the clutch pivot pin is when the transmission is removed, so this brass upgrade can be installed during clutch replacements or a rear main seal service.

Some modifications to your vehicle may not produce power to create gains in the overall performance of your driving. When you add a "Po' Boy" clutch stop to your BMW the performance gain is directly felt in the driving experience.

The ECS clutch stop allows the driver to fine tune the position of the clutch pedal to closely match the engagement point for precise, quicker shifting. The adjustment range found in this product can be set to the stock engagement point or can be adjusted to follow the wear of the clutch. Meaning your new experience will never change all the way to the end of the clutch life and can be reset to enjoy the next clutch.

Note: This modification might require some slight modification to the clutch switch mounting bracket, which can be bent slightly by hand.

  • Adjustable to eliminate aEURoedead travelaEUR after point of disengagement, which improves clutch pedal feel and results in faster gear changes
  • Further defines the engagement point for easier take-offs and launches
  • A practical, well-engineered solution to eliminating unnecessary long pedal travel
  • Professionally selected high quality parts by our in-house Engineering Team

Design:

  • Using custom-specaEURtmd hardware, our thread-in design is far superior to the competition. The advantage over a fir-tree style design (competition) is a much more rigid stop, that is going to stand up to repeated pedal mashing. This gives the user a more confident , OE-like feel.
  • No dense foam to compress, leaving a aEURoestickyaEUR or aEURoesquishyaEUR feeling after clutch depressed stroke
  • Polyurethane bumper to absorb shock during aggressive shifting
  • Zinc-coated hardware for corrosion protection
  • Zinc-alloy rivet nut makes a solid connection for the stop

Engineered in-house, we designed this lightweight, single-mass flywheel to provide more than 10 pounds of weight savings over the factory flywheel. While some ultra-lightweight performance flywheels are manufactured from aluminum, our designers opted for a more driveable experience with steel. The mass provided by steel helps dampen vibrations and noise, delivering near-factory refinement with most of the benefits of a lightweight flywheel: quicker throttle response, improved durability (and longevity), and more effective transfer of power to the wheels.

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.

When it comes to selecting a clutch to pair with a lightweight flywheel, consider the driving youaEURtmll be doing. As a single mass flywheel eliminates the dual-mass dampening of the factory flywheel, to retain the lowest noise, lowest harshness driving experience possible, select a clutch with a dampened disc. For dedicated track cars, a solid clutch hub is appropriate.

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 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. 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 -

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.

What was most important to them was offering a kit that has stock-like clutch pedal effort but will grab and hold when the car has been mildly tuned. Full bolt-on upgrades like software, intake, FMIC, E85 mix, or methanol demand a better clutch. The Stage 2+ with the flywheel has a peak torque rating of 545ft-lbs. With the SPEC single-mass flywheel the limitations of the stock flywheel are eliminated. The clutch in this Stage 2+ kit is self-adjusting, like the factory design, and the engagement point can be adjusted. The clutch disc has a sprung hub so it can be used with the single-mass flywheels with near-stock levels of noise, vibration, and refinement. See comments below for characteristics of each.

If you plan to go beyond bolt-ons, such as upgrading turbos or single turbo, we strongly recommended using the Stage 3+ clutch. The Stage 2+ offers the best drivability for 90% of the tuned 335s out there but when going beyond bolt-on upgrades it would be best to go to a more advanced clutch stage.

A lightweight aluminum flywheel is a great way to increase throttle response and free up horsepower by reducing drivetrain loss. Factory flywheels are built to minimize engine and transmission vibrations, making them heavier and requiring more energy to make them spin. An aluminum flywheel can save lots of weight over the stock steel unit - sometimes over 50%. While the dampening effect of the stock flywheel is reduced, most enthusiasts would agree that the increase in performance is well worth it. In addition, the lighter flywheel allows the engine to spin more freely, improving throttle response.

This JB Racing lightweight aluminum flywheel kit and is designed to be used with the included factory clutch, making replacement and service easy and inexpensive, especially compared to specialized racing clutches. It also preserves the driveability of your car on the street, and enthusiasts tolerant of a mild to moderate NVH increase will be especially taken with this setup. In addition, the JB Racing flywheel can be easily rebuilt with a new clutch contact surface, allowing you to enjoy faster revs and superior response for many years to come.

Stock Flywheel Weight: 24-31 lbs.

JB Racing Lightweight Aluminum Flywheel: 12 lbs.

Advanced Clutch Technology (ACT) designs, engineers and develops products by leveraging decades of track and performance street experience. Advanced CAD, FEA simulation, and CAM tools help ensure highly optimized performance, reliability, and repeatability. These key advantages are produced by combining the best engineering and design methodologies with the latest in materials and manufacturing techniques.

ACT clutch kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application while maintaining the predictable ACT pedal feel across the entire catalog.

This clutch kit features a Xtreme pressure plate and an R4 racing clutch disc.

Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.

Next in this kit is the R4 racing clutch disc. This disc is an unsprung, rigid disc with 4 pads that is best suited for drag and road racing. The R4 pads are composed of ceramic friction materials and the disc has a chome-moly hub that is heat treated for additional strength under high load engagements. Over stock, this disc is much better for faster shifting and significantly higher torque loads. Unlike the stock disc, this racing disk has a slightly shortened life span due to its rigid design and pad composition. This in turn is offset thanks to its fast, aggressive engagement for track use.

Advanced Clutch Technology (ACT) designs, engineers and develops products by leveraging decades of track and performance street experience. Advanced CAD, FEA simulation, and CAM tools help ensure highly optimized performance, reliability, and repeatability. These key advantages are produced by combining the best engineering and design methodologies with the latest in materials and manufacturing techniques.

ACT clutch kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application while maintaining the predictable ACT pedal feel across the entire catalog.

This clutch kit features a Heavy Duty pressure plate and an R4 racing clutch disc.

The heavy duty pressure plate included offers a 20-50% clamp load increase, stock-moderate pedal feel, and heat treated diaphragms for increased strength and performance.

Next in this kit is the R4 racing clutch disc. This disc is an unsprung, rigid disc with 4 pads that is best suited for drag and road racing. The R4 pads are composed of ceramic friction materials and the disc has a chome-moly hub that is heat treated for additional strength under high load engagements. Over stock, this disc is much better for faster shifting and significantly higher torque loads. Unlike the stock disc, this racing disk has a slightly shortened life span due to its rigid design and pad composition. This in turn is offset thanks to its fast, aggressive engagement for track use.
