ACT 1991 Toyota MR2 HD/Race Rigid 6 Pad Clutch Kit
ACT TM1-HDR6 is a race clutch for the SW20 Toyota MR2 Turbo. Our listing is titled for the 1991 MR2, and ACT catalogs the kit for the 1991-1995 MR2 Turbo with the 2.0L 3S-GTE. It is meant for the car that has outgrown a street clutch: a big-turbo 3S-GTE that slips at full boost, a track car that cooks organic discs, or a drag car that needs the clutch to hook every pass. If your MR2 is a daily driver, read the comparison below before you buy.
The kit combines ACT's T023 Heavy Duty pressure plate with the 6236007 six-pad rigid ceramic race disc. The plate's diaphragm is heat treated in four stages to raise clamp load and reduce deflection at high rpm. The disc uses ceramic friction pads on a heat-treated chromoly hub with no springs, which keeps it light so the gearbox shifts quicker, and ceramic tolerates far more heat than organic material. ACT rates the kit at 500 ft-lb at the crank, 69 percent over the factory clutch, with a 236 mm (9.3 in) disc on a 1.125 in input spline. The kit weighs 13.7 lb.
The trade-off is drivability. ACT lists the feel as light to moderate pedal effort with aggressive engagement and increased gear rattle, notes that the rigid design may increase spline wear, and recommends the kit for race use only. Without a sprung hub, engine pulses go straight into the transaxle, so expect more noise at idle and an on-off engagement.
Make sure the problem is the clutch. Bleed the hydraulics and check that the pedal returns fully, because a sticking slave cylinder can mimic slip. Look at the bellhousing for engine oil from the rear main seal, which will contaminate any disc. Then do a loaded test in third or fourth at low rpm and full throttle, watching for rpm that rises without the car pulling harder. Our slipping diagnosis guide walks through reading rpm against road speed, and the flare vs slip guide explains the difference.
ACT lists TM1-HDR6 for the 1991, 1992, 1993, 1994 and 1995 Toyota MR2 Turbo, 2.0L 3S-GTE DOHC. It is a Turbo-only kit; the non-turbo MR2 uses a different clutch. Many SW20s have had engine swaps or replacement flywheels, so check what is on the car and send us your year and VIN if you are unsure. For a street car, the TM1-HDSS sprung street kit uses the same plate with an organic disc. If you want a six-puck ceramic disc with a sprung center instead, see the Competition Clutch 3S-GTE sprung six-puck disc, and for maximum clamp the TM1-XTR4 Xtreme 4-pad kit.

ACT recommends it for race use only. The rigid ceramic disc engages aggressively and adds gear rattle. For the street, the TM1-HDSS sprung organic kit is the better fit.
ACT rates it at 500 ft-lb at the crank, 69 percent over the factory clutch.
No. ACT lists it only for the 1991-1995 MR2 Turbo with the 3S-GTE.
The T023 Heavy Duty pressure plate, the 6236007 six-pad rigid ceramic disc, the RB446 release bearing and the AT72 alignment tool.
The rigid disc is lighter for faster shifts but sends more vibration into the transaxle and may increase spline wear. A sprung six-pad disc damps that vibration at a small weight cost.
