SPEC billet flywheels offer precise engineering tailored to specific driving environments, ensuring optimal performance for each vehicle. Made from high-quality steel and aluminum, SPEC flywheels boast a .001 machine tolerance, guaranteeing a flat seating surface for the clutch and smooth rotational qualities. These flywheels are essential for converting OE Dual Mass to Single Mass for compatibility with Spec Design clutch Kits.
600315 is a Streetlite flywheel, which is considerably lighter than stock and is the most durable flywheel offering from ACT. Materials are properly distributed for maximum strength, lower inertia, good heat tolerance and rigidity. ACT's Streetlite flywheels are preferred for street or drag racing. ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.
Feel: Noticeably improved engine response and acceleration, OE to mild gear rattle;
Life: Heat-treated forging for strength and toughness, induction-hardened ring gears for maximum life;
Quality: One piece construction allows less opportunity for failure and provides uniform efficient heat transfer from the clutch disc. No more warped inserts or loose ring gears;
Recommended Use: Recommended for street and race use;
ACT Difference: Forged, CNC machined and dynamically computer balanced for smooth high RPM reliability;
For use with ACT clutch kits only.
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 is their most popular and features a Heavy Duty pressure plate and a Performance Street sprung clutch disc.
**Must be used with an ACT XACT Streetlite Flywheel, Part number: 600315**
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 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.

This clutch kit features a Heavy Duty pressure plate and a G6 racing clutch disc.
**Must be used with an ACT XACT Streetlite Flywheel, Part number: 600315**
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 G6 racing clutch disc. This disc is a sprung, 6-pad disc that is suited for high horsepower road and track style racing and is also better at handling higher heat versus the 4-pad version of this disc, the G4. The G6 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.

This clutch kit features a Heavy Duty pressure plate and a Modified racing clutch disc
**Must be used with an ACT XACT Streetlite Flywheel, Part number: 600315**
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 Modified Street Clutch Disc. This modified disc is a sprung street disc with an organic pad with high copper content and a steel backed lining, but is modified with reduced marcel for faster shift action. Also, these discs include stronger torsional springs that are rated properly for heavy duty use.

This clutch kit features a Heavy Duty pressure plate and R4 racing clutch disc
**Must be used with an ACT XACT Streetlite Flywheel, Part number: 600315**
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.
