ACT 1991 Geo Prizm HD/Race Sprung 6 Pad Clutch Kit
The ACT TC2-HDG6 is a race-oriented clutch kit for the small front-drive Toyota family: Geo Prizm, Toyota Corolla, Celica, Matrix, MR2 Spyder and Pontiac Vibe with the 1.6L or 1.8L DOHC four. Our listing title names the 1991 Prizm, but ACT's application list for this one part number runs from 1991 to 2013. It is built for a car that is turbocharged, supercharged or used hard on track, where an organic clutch is glazing or slipping and the owner can live with an aggressive take-up.
ACT pairs its Heavy Duty pressure plate (T030) with a 6-pad sprung ceramic race disc (6212103). The Heavy Duty diaphragm raises clamp load over stock while keeping the pedal light to moderate. The six ceramic pads tolerate far more heat than an organic facing, and the sprung hub damps engine pulses so the car stays drivable. ACT rates the kit at 305 ft-lb at the crank, 69 percent more than the original clutch. The disc is 212 mm (8.3 in) on a 0.9375 in input spline.
The trade-off is engagement. Pucks bite quickly, so expect on-off feel and some chatter from a stop. If the car is a daily driver with light mods, the organic TC2-HDSS uses the same plate with a smoother disc, and the TC2-XTSS adds the stiffer Xtreme plate while staying organic.
Run a load test in a high gear from low rpm at full throttle. If the tach rises ahead of road speed, the clutch is slipping. Grinding into gear or a pedal that sinks points to the release hydraulics or cable, not the friction. Our transmission slipping diagnosis guide walks through the test, and automatic vs. manual repair cost shows what a clutch job usually runs.
ACT lists TC2-HDG6 for the 1991-1997 Geo Prizm (GSi, Base, LSi, 1.6L and 1.8L), 1991-2005 Toyota Celica (ST, GT, GTS), 1992-2013 Toyota Corolla (including the 2005-2006 XRS), 2000-2005 MR2 Spyder, 2003-2013 Toyota Matrix (Base, XR, XRS) and 2003-2008 Pontiac Vibe Base and GT with the naturally aspirated engine. That spread covers several engine generations and both 5-speed and 6-speed gearboxes, so compare your transmission and flywheel before ordering, or send us your year, model and VIN to confirm. The full lineup is in our rebuild kits and clutch collection.
A ceramic disc needs a fresh, flat friction surface, so resurface or replace the flywheel. For the 1993-2002 Prizm and Corolla, the Competition Clutch 10 lb steel flywheel is a lighter option; ACT also lists its XACT Prolite flywheel 600515 alongside this kit for the later 1.8L cars. Center the disc with the ATK73 tool, torque the pressure plate bolts in a star pattern, and replace or bleed the release system with fresh brake fluid where the car is hydraulic. Check transaxle gear oil while the unit is out. ACT notes race discs only need a few firm slips to seat; avoid long slipping while the clutch is new, since overheating can glaze the faces.

No. ACT lists TC2-HDG6 for many years of Prizm, Corolla, Celica, Matrix, MR2 Spyder and Pontiac Vibe from 1991 to 2013. Send us your year, model and VIN to confirm.
It works, but engagement is aggressive and it can chatter from a stop. For a mostly street car the organic TC2-HDSS or TC2-XTSS is smoother.
ACT rates it at 305 ft-lb at the crank, 69 percent above the original clutch.
ACT lists four items: pressure plate, 6-pad disc, release bearing and alignment tool. These front-drive cars do not use a crank pilot bearing.
Resurface it or replace it. A ceramic disc on a glazed or uneven flywheel will chatter badly.
