ACT 1991 Geo Prizm HD/Perf Street Sprung Clutch Kit
ACT TC2-HDSS is a heavy duty street clutch kit that covers more than two decades of manual-transmission Toyota compacts and their GM twins. Our listing names the 1991 Geo Prizm, but ACT's chart for this one part number runs from the 1991 Prizm GSi and Celica ST through the 1992-2013 Corolla, the 2000-2005 Celica GT and GTS, the 2000-2005 MR2 Spyder, the Matrix and the Pontiac Vibe. It is the right kit when the original clutch is slipping, chattering or noisy and the car is a daily driver, maybe with an intake, exhaust or a swap to a higher-output 1.8L.
The clutch couples the engine to the five- or six-speed manual. Releasing the pedal lets the pressure plate diaphragm squeeze the disc against the flywheel, and engine torque passes through the disc into the input shaft. TC2-HDSS combines ACT's T030 Heavy Duty pressure plate with the 3000609 Performance Street sprung disc. The disc measures 212 mm (8.3 in) with a 0.9375 in spline, has a steel-backed organic facing with high copper content to shed heat, and uses a sprung hub for smooth street engagement. The same disc and release bearing go into ACT's Lotus kit; the pressure plate is what changes between the two.
ACT rates TC2-HDSS at 240 ft-lb at the crank, 32 percent over stock, with light to moderate pedal effort. That is plenty for a stock or bolt-on 1.6L or 1.8L. A turbocharged or supercharged build is better served by the TC2-XTSS Xtreme street kit, while a stock commuter can step down to the TC2-SPSS Sport kit, which ACT rates at 225 ft-lb, 24 percent over stock.
None of these faults sets a check engine light. Road test it: in fourth or fifth at about 2,000 rpm, press the throttle to the floor and watch the tach. A quick rise with little acceleration is slip. Our clutch slipping guide walks through that test, and the chatter on takeoff guide covers shudder, which is often a flywheel or engine mount issue as much as a disc. Also check the clutch fluid level and the slave or release arm before buying; a hydraulic fault can make a good clutch feel worn out.
ACT lists TC2-HDSS for manual-transmission versions of:
Because one kit spans several engines (ACT lists 1587, 1588, 1762, 1794, 1795 and 1798 cc versions), confirm that your car has the factory manual transaxle and one of those engines, then compare the old disc's diameter and spline before installing. Engine swaps are common on these cars, so fit the clutch to the engine and gearbox actually installed. Send us the year and VIN if you want it checked.

Yes. ACT recommends 300 to 500 miles of mild engagement on its organic street discs before hard driving.
