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.

This item fits the following BMW Chassis:
E61/1, E82/88, E9x, Z4

Fits the follow engines:

Enhance Your Car's Performance with the Perfect Clutch-Flywheel Combination

When it's time to replace your car's clutch, you face a crucial decision: upgrade or stick with stock? In many cases, upgrading is the preferred choice, especially when you pair the right clutch with a single mass flywheel. The secret to achieving the perfect blend of performance and driving experience lies in selecting a sprung hub clutch. This option allows you to enjoy the advantages of a single mass flywheel while eliminating issues like noise, vibration, and harshness (NVH), ensuring an outstanding driving performance.

SPEC's Stage 2 clutch features a full faced pure Kevlar disc complete with steel backing. This lining offers outstanding drivability like the Stage 1 kit, with an increased torque capacity and a longer life. The hub is double sprung with built-in spring reliefs for flexibility, along with heat treatment for added strength and durability. This clutch is best served in any situation from daily driven on the street, to drag or autocross racing events.

Kit includes:

Pressure plate
Clutch disc
Pilot bearing
Clutch Release Bearing
Clutch Alignment Tool
Clutch fork
Designed to be used with billet single mass flywheel

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 an Xtreme pressure plate, a Performance Street sprung clutch disc, and an XACT Streetlite Flywheel.

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 Performance Street clutch disc. This is the most popular sprung clutch disc and features high quality organic friction material with a high copper content for improved heat transfer and a steel backed lining for increased strength in burst load circumstances. This organic clutch disc has a significantly higher torque capacity than a stock disc but still retains a long life span and operates quietly and reliably.

Clutch Kit Specs:

• Torque Rating: 520 ft/lbs
• 68% torque capacity increase over stock!
• Type of Disc: Street
• 26-count spline
• Spline Size: 1-3/8" inch
• Disc Weight: 3.5 lbs
• Pressure Plate Weight: 10.7 lbs
• 1 year Warranty from retail purchase date!

This clutch kit features an Xtreme pressure plate and an R6 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 R6 racing clutch disc. This disc is an unsprung, rigid disc with 6 pads that is best suited for drag and road racing and handles heat better thanks to its increased surface contact area versus the 4 pad version of this disc, the R4. The R6 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.

Clutch Kit Specs:

• Torque Rating: 665 ft/lbs
• 117% torque capacity increase over stock!
• Type of Disc: Racing
• 26-count spline
• Spline Size: 1-3/8" inch
• Disc Weight: 4 lbs
