The EFORTISSIMO Stage 1 Sport Clutch Kit is designed to align with the 7M-GE’s torque characteristics, offering a performance bump without sacrificing daily usability. It targets drivers who want a firmer engagement and improved bite while maintaining smooth street manners. Best for casual street use with occasional spirited driving. Cautions include checking the vehicle’s drivetrain clearances and confirming fitment with your specific year and model variant.
Action Clutch Stage 1 Clutch Kit (1OS)
Action Clutch Stage 1 is positioned as an affordable performance upgrade. It emphasizes American design, assembly, and testing, with a 275 HP / 279 lb-ft rating. This kit suits owners seeking a noticeable upgrade over stock without extensive modification. Better for daily drivers who want more confident engagement, but users should beware of the limits at higher power builds or aggressive track use.
ClutchXperts Stage 2 Clutch Kit
ClutchXperts Stage 2 targets a practical middle ground: more torque capacity than Stage 1 with a straightforward install. Suitable for drivers who want higher power tolerance without entering aggressive multi-puck configurations. It’s best for daily driving with occasional spirited sessions. Limitations include a potential increase in pedal effort compared with stock, and compatibility checks for early 7M-GE builds.
ClutchXperts Stage 3 Clutch Kit
Stage 3 brings a stronger performance profile with a 338 HP rating and 6-puck copper ceramic clutch. This option is best for drivers who want more aggressive engagement and track-ready durability while still driving on public roads. Choose this if you’re targeting higher revs and more aggressive shifts; avoid if you regularly drive in stop-and-go traffic with a light foot on the pedal.
Action Clutch Stage 4 Clutch Kit
Stage 4 is designed for track-ready performance with a 338 HP / 345 lb-ft capability. It includes a high-quality ceramic 6-puck sprung disc and premium components for durability during aggressive driving. This kit suits dedicated enthusiasts who occasionally drive on the street but regularly participate in track or competitive events. The limitation is higher pedal effort and potential vibration under certain idle conditions.
Buying Guide
- What is your goal? Consider daily usability vs. track-oriented performance. Higher stage kits offer more grip but may require longer acclimation and stiffer pedal feel.
- What is your horsepower target? Match the kit’s torque rating to your planned power level to avoid clutch slip or chatter.
- Is the kit compatible with your year and model? The 7M-GE non-turbo setups vary slightly; verify fitment and any W58 transmission considerations.
- What driving conditions do you typically encounter? For frequent stop-and-go traffic, prioritize kits with smoother engagement; for occasional track days, stage-2 and above may be preferable.
- Warranty and support: Consider brands offering clear warranties and accessible technical support to reduce downtime during installation.
Quick buyer tips
- Prefer US-made or U.S.-engineered kits for easier parts availability and technical guidance.
- Inspect included components: a complete kit with pressure plate, disc, throwout bearing, and alignment tool simplifies installation.
- Prepare for installation with the right tooling and, if needed, professional assistance to ensure proper clutch alignment and manifold clearance.
