ACT 1999 Acura Integra XT/Race Sprung 6 Pad Clutch Kit
The ACT AI4-XTG6 pairs ACT's Xtreme pressure plate with a six-pad, spring-hub ceramic race disc for the B-series Honda and Acura five-speed. It is for a 1999 Acura Integra GS-R or LS that has been boosted, sprayed or built and now slips in the upper gears, or for a drag car that keeps glazing an organic street disc. ACT rates it at 410 ft-lb at the crank, 120 percent over the factory clutch.
The factory Integra clutch uses a full-face organic disc and a pressure plate sized for stock power. The XTG6 raises clamp load with the H025X Xtreme diaphragm and swaps the friction ring for six ceramic pads on a 220 mm (8.7 in) disc. Ceramic pads hold through heat that would glaze an organic facing, and the sprung center absorbs driveline shock on launches and takes the edge off gear rattle. ACT recommends this kit for high-horsepower street or race use. It sits one step below the MaXX version: if 410 ft-lb covers your build with margin, the XTG6 gives a lighter pedal than the ACT AI4-XXG6 MaXX kit. ACT says to expect 50-80 percent more pedal effort with an Xtreme plate, and a six-pad disc engages quickly.
Most 1994-2001 Integras use a cable clutch. A cable with no free play keeps the bearing on the diaphragm and causes slip no new clutch can cure, so check free play at the pedal first. Then do a full-throttle pull in fourth from low RPM: a flare without acceleration means the disc is slipping. Look for oil at the bellhousing too, since a leaking rear main or input seal will contaminate new pads. Our slipping diagnosis guide and the clutch slipping causes page cover these checks.
Our listing is titled for the 1999 Integra. ACT's application chart for AI4-XTG6 is wider: 1994-2001 Acura Integra 1.8L (B18B1, B18C1, B18C5) five-speed, 1994-1997 Civic del Sol 1.6L VTEC DOHC, 1999-2000 Civic Si 1.6L VTEC, and 1998-2001 CR-V EX and LX 2.0L. D-series and K-series cars need different kits. On a swapped car, match the transmission, not the chassis, and send us the year and VIN or the engine and gearbox codes before ordering. Compare every option in our clutch and rebuild kit collection; for a milder street pedal on the same car, see the ACT AI4-HDG6 HD race kit.
No flywheel is included; ACT sells its 600105 Prolite and 600110 Streetlite XACT flywheels separately.

ACT lists it for 1994-2001 Integra 1.8L B18B1, B18C1 and B18C5 five-speeds, 1994-1997 del Sol VTEC, 1999-2000 Civic Si and 1998-2001 CR-V. Our listing is titled 1999 Integra. Send the year and VIN if you want us to confirm.
It is a race-oriented kit. ACT recommends it for high-horsepower street or race use, and a six-pad ceramic disc engages quickly with an Xtreme plate adding 50-80 percent pedal effort. A daily-driven mild build is usually happier with an HD street kit.
Both use the same six-pad sprung race disc. The XTG6 uses the Xtreme pressure plate rated at 410 ft-lb; the XXG6 uses the MaXX Xtreme plate rated at 485 ft-lb with an even heavier pedal.
No flywheel comes in the kit. Resurface the stock one if it is in spec, or replace it. Ceramic pads on a glazed or heat-checked surface chatter.
Most 1994-2001 Integras use a cable-operated clutch, so there is nothing to bleed; set the cable free play after install. Hydraulic-release chassis in the application list are bled with fresh brake fluid.
