ACT 1991 Geo Prizm Sport/Perf Street Sprung Clutch Kit
The ACT TC2-SPSS is the entry-level performance clutch in ACT's lineup for the small Toyota-engined manual cars: the Geo Prizm, Corolla, Celica, Matrix, Pontiac Vibe and MR2 Spyder. Our listing title only names the 1991 Prizm, but ACT catalogs this one kit from 1991 through 2013. Buyers usually land here because the original clutch has started slipping in the higher gears, shudders when pulling away, or the release bearing has begun to howl, and they want a replacement that holds a little more than stock without turning a commuter into a chore to drive.
In a front-drive Corolla, Prizm or Celica, and in the mid-engine MR2 Spyder, the clutch sits between the flywheel and the manual transaxle. The pressure plate's diaphragm spring clamps the disc against the flywheel; pressing the pedal pushes the release bearing into the diaphragm fingers and lifts that clamp so you can change gears. How hard the plate clamps decides how much torque the disc can carry before it slips.
TC2-SPSS pairs ACT's T030S Sport pressure plate with the 3000609 Performance Street sprung disc. ACT rates the package at 225 ft-lb at the crank, 24 percent more than the factory clutch, and describes the feel as light to moderate pedal effort with smooth engagement. The disc is 212 mm (8.3 in) across with a 0.9375 in input spline and an organic, high-copper facing on a steel backing, and the sprung hub soaks up driveline shock on a street car. For a stock engine or light bolt-ons, that margin is the point: it fixes the slipping without the firmer pedal of the heavier plates. If the car makes real power, step up to the TC2-HDSS Heavy Duty kit instead, which uses the same disc with a stronger plate.
None of this sets a check engine light, so the diagnosis is done by feel and inspection, not with a scan tool.
First rule out the release side. On cars with hydraulic clutch control, check the reservoir level and look for wetness at the slave cylinder; a cable-operated car needs the cable and free play checked. Then do a load test: in fourth gear at roughly 2,000 rpm, go to full throttle and watch the tachometer. If the needle jumps ahead of the speedometer, the disc is slipping. Our clutch slipping guide explains the test in detail, and the slipping diagnosis guide helps separate a clutch fault from other drivetrain problems. Oil on the bellhousing seam is worth a look too, because a leaking rear main seal will contaminate any new disc.
ACT's application chart for TC2-SPSS covers manual-transmission versions of these cars:
That list spans several engine families, from the 1.6L Prizm GSi to the 1.8L engines in the later Corolla and Matrix. Engine and transmission swaps are common on these cars, so match the clutch to what is actually bolted in: compare the old disc's diameter and spline with the 212 mm and 0.9375 in figures above before you install. If you want us to check it, send the year and VIN with your order. Other clutch parts are in our rebuild kits and clutch section.

No. ACT lists the same kit for manual 1991-1997 Prizm, 1992-2013 Corolla, 1991-1997 Celica ST, 2000-2005 Celica GT/GTS and MR2 Spyder, 2003-2013 Matrix and 2003-2008 Vibe. Our title just carries the first year on ACT's list.
Both use the same 3000609 sprung disc, RB840 bearing and ATK73 tool. The Sport kit has the T030S plate rated 225 ft-lb (24 percent over stock); the HDSS kit has the T030 Heavy Duty plate rated 240 ft-lb (32 percent over stock).
ACT describes TC2-SPSS as light to moderate pedal effort with smooth engagement, so it is intended to stay comfortable for daily driving.
The kit does not include one. At minimum have the factory flywheel resurfaced; replace it if it is cracked, heavily heat-spotted or below minimum thickness.
The 225 ft-lb rating is aimed at stock and lightly modified engines. For forced induction, ACT's Heavy Duty or Xtreme kits for the same cars are the better match.
ACT recommends 300 to 500 miles of mild engagement on its organic street discs before aggressive driving.
