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 features a Heavy Duty pressure plate, a Performance Street sprung clutch disc, and an XACT Streetlite Flywheel.
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 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.
The final main component is the XACT Streetlite Flywheel. This option is the most popular thanks to it versatility for street driving and drag/track style racing, its lighter weight for increased throttle response, and its single mass design.

Clutch Kit Specs:
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.
This clutch package is designed for high HP vehicles desiring a start performance similar to O.E. The pressure plate is Race Engineered (SS) and SFI approved with significant load increase over stage 1,2 pressure plates (+600-800 lbs.). Expect a pedal effort increase of 20%-25%. Discs are assembled with heat-treated wear resistant hubs; drive plates and springs for high load transfer and dependable operation. The sprung centers on the disc in conjunction with the marcel fin between the linings create a dual dampening effect that simulates O.E. start performance. A Performance Organic friction material with a high metal content increases torque and RPM capability and maintains low operating temperatures which reduces wear and glazing.

Upgrade your Mini's clutch system with the Performance Clutch Installation Kit, ideal for stage one clutch upgrades. This kit includes everything you need for installation, featuring the FX400 (Stage 2) clutch. Benefits include:
| #SB533H-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. |
This comprehensive performance clutch installation kit is your ticket to an exciting stage one clutch upgrade. It's equipped with an aluminum flywheel, providing all the essential components for enhancing your car's performance.
The FX300 (Stage 3) clutch system is designed for high-performance street driving.
