ACT 07-13 Mazda Mazdaspeed 3 2.3L Turbo XT/Perf Street Sprung Clutch Kit
A tuned Mazdaspeed3 finds the limit of the factory clutch quickly. Once the turbo is spooled and the car is in third or fourth, a worn or overmatched stock clutch lets the revs flare while road speed lags behind. The ACT ZX5-XTSS is built for that owner: an Xtreme pressure plate with the highest clamp load in ACT's single-disc street line, paired with a smooth organic disc so the car still drives normally in traffic. It fits the 2007-2013 Mazdaspeed3 with the 2.3L turbocharged engine.
The Mazdaspeed3 came from Mazda with 263 hp and 280 lb-ft from its 2.3L direct-injection turbo four, fed to the front wheels through a six-speed manual. That is a lot of torque for a front-drive clutch, and most of it arrives low in the rev range, which is exactly where a tired disc gives up first. ACT rates ZX5-XTSS at 532 ft-lb at the crank, 79 percent over the original clutch, so it has margin for intake, downpipe, tune and fuel upgrades.
The kit pairs the MZ031X Xtreme pressure plate with the 3000215 Performance Street sprung organic disc (240 mm, 1 in input). The sprung hub damps driveline shock and the organic facing engages progressively, so the trade-off over stock is pedal effort, not drivability. ACT describes the feel as moderate to heavy pedal effort with OE to mild gear rattle. It is a conversion kit: the 600641 XACT Streetlite single-mass flywheel is in the box and replaces the factory flywheel.
Do a controlled test: fourth gear around 2,500 rpm, then full throttle. If the tach jumps ahead of the speedometer, the clutch is slipping and no amount of fluid or adjustment will fix it. If the pedal feels soft or gears grind, look at the hydraulic release side first. Our slipping diagnosis guide walks through separating real slip from other problems, and the Mazdaspeed3 clutch replacement and upgrade guide covers what the job costs and which upgrade level suits which build.
The listing covers the 2007-2013 Mazdaspeed3 with the 2.3L turbo. ACT also lists the same kit for the 2006-2007 Mazdaspeed6, which shares the engine. It does not fit the non-turbo Mazda3, which uses a different clutch and transmission. If the car has had an engine or transmission swap, send the year and VIN before ordering. For a lighter pedal on a mildly modified car, compare the ZX5-HDSS Heavy Duty street kit; for a track car, the ZX5-HDG6 race kit. More clutch kits are in our rebuild kits collection.

No. It is for the turbocharged 2007-2013 Mazdaspeed3 (and per ACT, the 2006-2007 Mazdaspeed6). Non-turbo Mazda3 models use a different clutch.
Yes. ACT includes its 600641 XACT Streetlite single-mass flywheel, along with the pilot bearing, release bearing and alignment tool.
ACT rates ZX5-XTSS at 532 ft-lb measured at the crank, 79 percent more than the factory clutch.
Yes. The Xtreme pressure plate raises clamp load, and ACT describes the pedal as moderate to heavy. If you want a lighter pedal and run moderate power, the Heavy Duty ZX5-HDSS is the better match.
The kit covers the flywheel, bearings and friction parts. Check the rear main seal, input seal and clutch slave or release hydraulics while the transaxle is out, and refill the transmission with the manual transmission fluid Mazda specifies.
