ACT 1988 Toyota Supra XT/Perf Street Sprung Clutch Kit
ACT TS2-XTSS pairs ACT's stiffest single-disc pressure plate with a full-face organic street disc for the third-generation Toyota Supra Turbo and its 3.0L 7M-GTE inline six. Our listing is for the 1988 car. It suits a Supra that has gained boost, a larger turbo or a tune and now slips at full load, but whose owner still wants the smooth takeoff of an organic clutch rather than the grab of a ceramic race disc.
ACT ships five parts: the T015X Xtreme pressure plate, the 3000608 Performance Street sprung disc, an RB419 release bearing, a PB1004 pilot bearing and the AT11 alignment tool. A flywheel is not included.
The Xtreme diaphragm is where the holding power comes from. It clamps harder than ACT's Heavy Duty plate, so the same style of organic disc can hold more torque before it lets go. ACT rates TS2-XTSS at 495 ft-lb at the crank, 63 percent over the factory clutch, on a 9.4 in (240 mm) disc with a 1.125 in input spline. For comparison, the TS2-HDSS with the Heavy Duty plate is rated 445 ft-lb, and the TS2-XTG6 keeps this Xtreme plate but swaps in a ceramic six-pad disc for 630 ft-lb.
The cost of the stronger plate is pedal feel. ACT describes moderate to heavy pedal effort with smooth engagement and OE to mild gear rattle. The disc uses a high-copper, steel-backed organic lining and a sprung hub that absorbs the torsional pulses of a turbo six, so stop-and-go driving stays civil even though the pedal is firmer.
Start with the hydraulics. A soft pedal, grinding into gear or a clutch that will not fully release points to the master cylinder, slave cylinder or air in the line rather than a slipping disc. For a slip test, use third gear from low rpm, go to full boost and watch whether engine speed outruns road speed. Our slipping diagnosis guide covers the procedure and shift flare vs. slip explains what the tach is showing you. Look for oil weeping from the bellhousing; a rear main seal leak will contaminate a fresh disc.
ACT's chart for TS2-XTSS lists the 1986-1992 Toyota Supra with the turbocharged 2954 cc engine, plus the JDM Supra 2.5 GT Twin Turbo (1986-1992) and JDM Soarer GT (1991-1996). Our listing is for the 1988 Supra Turbo. Non-turbo MK3 Supras and the 1993-1998 MK4 are not on that chart. Because ACT offers several TS-series kits with near-identical names, match the part number TS2-XTSS to your car, or send us your year and VIN and we will check it before it ships. More clutch parts are in our rebuild kits section.

No. The kit has the T015X pressure plate, 3000608 disc, RB419 release bearing, PB1004 pilot bearing and AT11 alignment tool. Resurface your flywheel or replace it.
ACT describes moderate to heavy pedal effort for this kit. Healthy hydraulics make a big difference, so replace a weak master or slave cylinder during the install.
