XClutch 06-07 Mazda Mazdaspeed 3 2.3L Turbo Stage 1 Sprung Organic Clutch Kit
The 2.3 liter MZR DISI turbo in the Mazdaspeed makes big midrange torque, and once a car has an intake, downpipe or tune the factory clutch is usually the first thing to give up. XClutch XKMZ24530-1A is a Stage 1 street kit for that car: a sprung organic disc, a heavy duty diaphragm pressure plate and a flywheel in one box. If your Mazdaspeed revs up in third or fourth gear without pulling harder, the bite point has climbed to the top of the pedal, or the original flywheel is worn or noisy, this is a drop-in way to fix all of it at once.
XClutch is designed in Australia by Australian Clutch Services. Its Stage 1 sprung organic kits are aimed at road cars: more clamp load and torque capacity than stock while keeping a light, predictable pedal. For this part number XClutch lists a 77 percent clamping force increase over the original and a torque capacity of 440 ft-lb including its factor of safety, which covers most bolt-on and mild tune builds on the factory turbo.
The disc is 9 7/16 inch (240 mm) with an organic facing and a sprung hub. The springs soak up driveline shock and the organic material engages progressively, which is what you want in traffic. XClutch lists a 23 spline hub for a 1 1/32 inch input shaft. The kit ships with a flywheel, and XClutch includes its single mass flywheel bulletin with it.
Do a slip test: in fourth gear at about 2,500 rpm, go to full throttle. If engine speed rises faster than road speed, the clutch is slipping. Bleed the clutch hydraulics and check that the pedal returns fully first, because a dragging master or slave cylinder can mimic a worn disc. Our slipping diagnosis guide walks through separating clutch slip from other drivetrain problems, and flare vs. slip explains what the rpm needle is telling you. If you are deciding between repair options, see our manual repair cost guide.
Our listing data for XKMZ24530-1A reads 2006-2007 Mazda Mazdaspeed 3 with the 2.3 liter turbo. In North America the Mazdaspeed3 was sold from the 2007 model year through 2013, and the 2006-2007 Mazdaspeed6 uses the same 2.3 liter turbo engine. Clutch hardware on these cars is commonly shared, but do not order on that assumption alone. Send us your year, model and VIN and we will confirm the kit matches your car before it ships. This kit is not for the non-turbo Mazda3 2.0 or 2.3. Browse more parts for these cars in our rebuild kits and clutch category.
Expect a little more gear rattle at idle with a single mass flywheel; XClutch notes this is normal and not a fault. If you need more holding power for a big turbo build, compare the Clutch Masters 725 twin disc kit or the ACT ZX5-XTSS.

XClutch TSB-226 calls for the six M8 pressure plate bolts to be tightened evenly in stages and torqued to 26 ft-lb (35 Nm). Flywheel bolts go to the factory spec.
Single mass flywheels pass more engine harmonics into the gearbox, which can show up as rollover rattle at idle. XClutch notes this does not affect the clutch or the vehicle.
