ACT 2002 Audi TT Quattro HD/Perf Street Sprung Clutch Kit
The first-generation Audi TT quattro with the 1.8T is one of the easiest cars to add power to, and one of the first things to give up after a chip, a bigger intercooler or a hybrid turbo is the original clutch. ACT VW5-HDSS is a street-focused upgrade cataloged here for the 2002 TT quattro. It combines a Heavy Duty pressure plate, an organic Performance Street disc and a lightweight flywheel, rated by ACT at 410 ft-lb at the crank, about 35 percent more than the factory clutch.
The VW013 pressure plate uses ACT's heat-treated diaphragm to raise clamp load and limit deflection at high rpm, which is where a stock plate starts to let a tuned 1.8T slip. The 3000703 disc is a sprung, full-face organic disc with high copper content for heat transfer and a steel-backed lining for burst strength. The result is a clutch that drives close to stock in traffic: ACT describes light to moderate pedal effort and smooth, positive engagement, with OE to mild gear rattle.
ACT requires its own flywheel with this kit, so the box includes the XACT Streetlite flywheel (600820), the RB3743A release bearing and the AT126 alignment tool, plus flywheel bolts (M10-1.0 x 22 mm) and pressure plate bolts (M8-1.25 x 16 mm). Disc size is 240 mm (9.4 inch) with a 0.9375 inch input spline, and the kit weighs about 30.9 lb.
Slip at full boost on a modified 1.8T usually means the clutch is worn or out of clamp load, but rule out the simple causes first. On these cars the clutch hydraulics draw from the brake fluid reservoir, so check that level, bleed the slave cylinder and make sure the pedal comes all the way back. Look for oil weeping from the rear main seal or gearbox input seal at the bellhousing seam, because contaminated friction will slip no matter how strong the plate is. Our slipping diagnosis guide lists the checks step by step, and the shift flare versus slip guide helps tell a true clutch slip from a tuning issue.
Our listing is cataloged for the 2002 Audi TT quattro with the 1.8 liter turbo four and a manual gearbox. ACT's own chart for VW5-HDSS is wider: it lists the 2000-2006 TT quattro (Base, S Line and ALMS Edition), the 2002-2004 Beetle Turbo S, the 2002 GTI 337, the 2003 GTI 20th Anniversary and the 2004-2005 Jetta GLI, all with the 1.8T. ACT does not list front-drive TTs or automatic cars under this part number. TT quattro models were built with more than one manual gearbox, so match your transmission or send the year and VIN before ordering. More kits are in our rebuild kits department.

ACT rates it at 410 ft-lb measured at the crank, about 35 percent over the factory clutch. That suits most chipped and bolt-on 1.8T cars; larger turbo or track builds should look at ACT's VW5-HDG6 six-pad race kit, rated at 525 ft-lb.
Yes. It uses a full-face organic disc with a sprung hub, and ACT describes light to moderate pedal effort with smooth engagement. Expect a somewhat firmer pedal than stock; ACT says its Heavy Duty plates add roughly 15 to 40 percent pedal effort depending on the car.
ACT's chart also lists the 2000-2006 TT quattro, 2002-2004 Beetle Turbo S, 2002 GTI 337, 2003 GTI 20th Anniversary and 2004-2005 Jetta GLI. Our listing is cataloged for the 2002 TT quattro, so send your year and VIN if you want us to confirm another car.
No. ACT states the kit must be used with the ACT flywheel, and the XACT Streetlite flywheel is included along with flywheel and pressure plate bolts.
The release bearing is already in the kit. Most owners also replace the rear main seal and gearbox input seal if they show any seepage, and bleed the clutch hydraulics with fresh fluid.
