Upgrade your BMW's performance with the BMW E46 Z3 Stage 2 Endurance Clutch Kit, designed for durability and enhanced driving experience. This clutch kit is engineered to handle increased torque and power while maintaining everyday drivability. Perfect for enthusiasts looking to improve clutch performance without sacrificing comfort.

• Enhanced durability for endurance driving
• Handles increased torque and power
• Maintains smooth and precise clutch engagement
• Suitable for both street and track use

Experience improved clutch performance with the BMW E46 Z3 Stage 2 Endurance Clutch Kit.

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 a G4 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 G4 racing clutch disc. This disc is a sprung, 4-pad disc that is suited for high horsepower road and track style racing. The G4 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. Also featured are heavy duty torsional springs that are rated for the clutch kit's expected uses. Over stock, this clutch kit has a much higher torque capacity and is better for quick shifting thanks to lower weight and inertia. Despite its ceramic racing style pads, this disc has great durability. In turn, these pads provide higher heat tolerances and faster, more aggressive clutch engagements.

Clutch Kit Specs:

• Torque Rating: 505 ft/lbs
• 83% torque capacity increase over stock!
• Type of Disc: Racing
• 10-count spline
• Spline Size: 1-1/8" inch
• Disc Weight: 3.4 lbs
• Pressure Plate Weight: 11.2 lbs
• 1 year Warranty from retail purchase date!

BMW E46 E39 Z3 Stage 2 Endurance Clutch Kit is designed for drivers who demand both precision and durability in high-performance scenarios. Developed by Turner Motorsport, this endurance clutch kit delivers seamless power transfer and quick shifts, making it ideal for both daily driving and intense racing environments. It features an SFI-approved single mass flywheel, which is highly recommended for optimal performance.

• Engineered for durability in daily and street use with a focus on rally and endurance racing
• Rated conservatively to handle up to 385 lbs/ft of torque, providing confidence in high-power applications
• Precision-balanced pressure plate ensures vibration-free operation even at high RPM
• Positive disengagement and fast shifts due to altered pressure plate fulcrum, perfect for competitive driving
• Dual-damped disc design delivers smooth, controlled acceleration through corners, enhancing driving dynamics
• Hybrid friction material with Feramic (Sintered Iron) on the flywheel side and high-metal organic lining on the pressure plate side offers a positive yet buffered engagement
• High graphite content in Feramic facings adds to smoothness and longevity
• Solid-hub center section compatible with OE dual-mass flywheel

This clutch package is built to handle heavily modified cars and designed to function according to the specific needs of the 1/4 and 1/8 mile track. The pressure plate for this kit is SFI approved Race Cover engineered to disengage with less pedal travel shortening the shift time. Discs are a puck design, which reduces rotational mass and are assembled with all high carbon component pieces for maximum strength. The friction material used is Graphite impregnated Ceramic perfectly suited for drag racing because of its maximum friction co-efficient, rapid heat dissipation and abrupt engagement characteristics.

Stage 3 Drag/Drift Clutch Kits:

Recommended uses are drag, pulling, drifting

Conservatively rated to hold 650lbs/ft of torque

Featuring a solid-hub center section for use with an OE dual-mass flywheel

Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).
