ACT 1991 Geo Prizm XT/Perf Street Sprung Clutch Kit
The ACT TC2-XTSS is the high-clamp street clutch for the small Toyota front-drive cars: Geo Prizm, Toyota Corolla, Celica, Matrix, MR2 Spyder and Pontiac Vibe with the 1.6L or 1.8L DOHC four. Our listing names the 1991 Prizm GSi, and ACT's own application chart for this part number runs from 1991 through 2013. It suits a car with a swap, a turbo or supercharger, or simply a factory clutch that now slips in the upper gears and chatters pulling away, where the owner still wants an organic disc that behaves in traffic.
The kit combines ACT's Xtreme pressure plate with a sprung Performance Street organic disc. The Xtreme diaphragm is the stiffest plate ACT offers for this application, so it raises clamp load and resists deflection as revs climb, which is what keeps a modified 1.8L from flaring the tach at the top of third. The disc keeps an organic facing with high copper content for heat transfer and a steel-backed lining for burst strength, and its sprung hub soaks up the shock a light front-drive car sends through the axles on a hard launch.
ACT rates the TC2-XTSS at 310 ft-lb measured at the crank, 74 percent over the original clutch. The disc is 212 mm (8.3 in) on a 0.9375 in input spline, and the kit weighs 12.8 lb. ACT lists the feel as moderate to heavy pedal effort, smooth engagement and OE to mild gear rattle, and rates it for street and race use. What is in the box:
If the car is mildly modified and you want a lighter pedal, the TC2-HDSS pairs the same style of disc with ACT's Heavy Duty plate. If an organic disc is already glazing on track, the puck-style TC2-HDG6 trades street manners for heat tolerance.
Rule out the easy causes first. These cars use a hydraulic release, so bleed the system and check for a low or contaminated reservoir and a pedal that does not return fully. Look at the bottom of the bellhousing for oil from the rear main seal or transaxle input seal, because oil on a new disc will make it slip just like the old one. Then do a steady low-rpm, full-throttle pull in a high gear and watch the tach against road speed. Our slipping diagnosis guide walks through that test, and flare versus slip helps separate a clutch problem from a shift problem. If you are weighing a clutch job against other repairs, see manual versus automatic repair cost.
ACT's chart for TC2-XTSS covers manual-transmission versions of these cars:
Because one part number spans several engines and two decades, check that your car has the manual transaxle and the 1.6L or 1.8L DOHC engine listed, and compare the old disc diameter and spline before the new kit goes in. If the car has had an engine or transaxle swap, fit the clutch to the swapped engine and gearbox, not the badge on the car. Unsure? Send us the year and VIN and we will check it before you order.

Yes, ACT lists it for 1.6L and 1.8L DOHC manual-transmission Prizm, Corolla, Celica, Matrix, Vibe and MR2 Spyder models from 1991 to 2013. Confirm your car has the manual transaxle and one of those engines.
The T030X Xtreme pressure plate, the 3000609 Performance Street sprung organic disc, the ATK73 alignment tool and the RB840 release bearing. A flywheel is not included.
ACT rates it at 310 ft-lb at the crank, 74 percent more than the factory clutch, which leaves wide margin for a turbocharged or supercharged 1.8L.
ACT describes the Xtreme plate as moderate to heavy pedal effort. If you mostly drive in traffic on a mild build, the Heavy Duty TC2-HDSS gives a lighter pedal.
Resurface or replace the flywheel, replace the pilot bearing where fitted, check the fork and pivot, and flush the clutch hydraulic fluid. Fix any rear main or input seal leak before the new disc goes in.
Drive gently for 300 to 500 miles, ideally in stop-and-go traffic, before launching hard or racing, and avoid overheating the clutch during that period.
