ACT 1988 Toyota Supra HD/Perf Street Sprung Clutch Kit
The ACT TS2-HDSS is the everyday upgrade for the MK3 Toyota Supra Turbo. If your 7M-GTE car slips on boost, chatters leaving a stop, or you are replacing a tired 30-year-old clutch and want margin for a few bolt-ons, this kit gives you a stronger clutch without the race-car pedal or the harsh engagement of a puck disc. The listing says 1988, but the same kit covers every turbo MK3 on ACT's chart.
The turbocharged 2954 cc inline-six builds torque quickly once boost arrives, and an aging stock pressure plate loses clamp load as its diaphragm fatigues. ACT's T015 Heavy Duty pressure plate uses a heat-treated diaphragm designed to raise clamp force and reduce deflection, matched to a 240 mm (9.4 in) Performance Street sprung organic disc. ACT rates the package at 445 ft-lb at the crank, 47 percent over OE.
This is the mildest of ACT's TS2 kits. Next step up is the Xtreme-plate TS2-XTSS at 495 ft-lb, and above that the 6-pad race discs. For a street Supra on stock or lightly modified turbos, the HDSS keeps the smooth full-face engagement and quiet sprung hub that make the car pleasant to drive every day.
On a car this age, check the hydraulics first. Look at the clutch master and slave cylinders for leaks and dark fluid, and confirm the pedal comes back fully. If the hydraulics are healthy, do a low-RPM, high-gear full-throttle test; a tach that climbs faster than road speed confirms slip. Our slipping diagnosis guide covers the test, and the flare versus slip article helps you describe what you are feeling.
ACT lists the TS2-HDSS for the MK3 Toyota Supra with the 3.0L turbocharged inline-six (7M-GTE), 1986 through 1992 model years, plus the JDM Supra 2.5 GT Twin Turbo (1986-1992) and Soarer GT (1991-1996). Non-turbo MK3 Supras are not on the chart, so confirm your car is a factory turbo or has had the turbo drivetrain swapped in. Input shaft is 1.125 in. If you have swapped in a different transmission, match the input spline before ordering, or send us the year and VIN. Browse more MK3 parts in our rebuild kits and clutch section, or compare the TS2-XTSS Xtreme kit if the car makes more power.
No flywheel is included. Resurface the original flywheel, or replace it if it is heat-checked or below minimum thickness; we stock a 13.7 lb steel flywheel for the MK3 Supra Turbo. Pull the old pilot bearing and fit the supplied PB1004, center the disc with the AT11 tool, and bring the pressure plate down in a star pattern. On a car this old, it is worth replacing the clutch slave cylinder and flushing the hydraulics with fresh brake fluid of the grade marked on the reservoir while the gearbox is out. If you only need the plate later, the T015 pressure plate is sold on its own. Give the organic disc 300 to 500 miles of easy driving to bed in.
