Specs.:

• All Clutch Kits are complete with Pressure Plate, Clutch Disc, Throwout Bearing, and Clutch Alignment Tool.
• Stage 1 Clutch Kits:Steel-backed woven organic disc w/ a 410 rear wheel torque capacity.  Smooth chatter-free engagement with factory pedal.
• Stage 2 Clutch Kits:Pure kevlar disc w/ a 520 rear wheel torque capacity.  Smooth engagement with a factory, to slightly stiffer pedal.
• Stage 2+ Clutch Kits:Composite multi-friction carbon-kevlar disc w/ a 620 rear wheel torque capacity.  Smooth engagement with a factory, to slightly stiffer pedal.
• Stage 3 Clutch Kits:3-Piece disc with SPEC's exclusive X-Pad material, which is a combination of carbon and ceramic material and a 6-wing design.  The Carbon material adds a little better feel for the street, while the ceramic material adds a more aggressive feel.  Sharp but smooth engagement, light pedal, and a 680 rear wheel torque capacity.
• Stage 3+ Clutch Kits:3-Piece disc with SPEC's exclusive X-Pad material, which is a combination of carbon and ceramic material and a full face clutch disc.  The Carbon material adds a little better feel for the street, while the ceramic material adds a more aggressive feel.  Sharp but smooth engagement, light pedal, and a 800 rear wheel torque capacity.
• Stage 4 Clutch Kits:2-Piece rigid disc.  Available in 3, 4, or 6 wing design for serious road racing or drag racing, and a 680 rear wheel torque capacity.  3 or 4 wing is recommended for Road Racing.  The 3 wing will be lighter, with a harsher engagement, while the 4 wing will be slightly heavier, with a less harsh engagement.  The 6 wing is recommended for drag racing or street use.
• Road Race Clutch Kits:Any clutch kit can be converted to a "Road Race" clutch.  Road race clutch kits feature a billet aluminum pressure plate which is 6 lbs. lighter than a standard pressure plate.  To upgrade the standard pressure plate, add an "A" after the SF in the part number.  The cost of the upgrade is $200.00.
• Aluminum Flywheels:Ultra light weight design allows engine to rev quicker.  Easier off the line than a standard or billet flywheel.  Has removable sections that can be replaced due to wear.   
• Please Note:For Transmissions with  a 26-spline input shaft, please add a "T" to the end of the part # for the clutch kit you would like to order.  The same applies for clutch discs.  Tremec 3550 Transmissions have 10-spline input shafts just like T-5/T-45/Tremec 3650 Transmissions.  Factory T-56 Transmissions also have 10-spline input shafts.  "Viper" T-56 transmissions have 26-spline input shafts.  Tremec TKO 500 Transmissions are available with 10-spline and 26-spline input shafts.  TKO 600 transmissions have 26-spline input shafts.
• Romeo Blocks:Feature 11 Valve Cover Bolts.
• Windsor Blocks:Feature 14 Valve Cover Bolts.

Notes:

• (1):These clutch kits must be used in conjunction with a SPEC Billet Steel or Aluminum Flywheel.  This will convert from the factory 11.0" clutch to a 10.5" clutch, which has proven to work better with the 2005-2007 GT's hydraulic clutch design.
