Clutch Masters 06-12 Lexus IS250 2.5L 6-Speed FX100 Dampened Disc Clutch Kit
The Clutch Masters 16250-HD00-D is an FX100 street clutch kit for the 2006-2012 Lexus IS250 with the 2.5L V6 and the 6-speed manual. IS250 owners usually come looking for it when the original clutch starts to slip on the highway, the engagement point creeps to the top of the pedal, or the car shudders pulling away after well over a decade of commuting. It is also a sensible step up for cars with an intake and exhaust that want a little more grip without a heavier pedal.
In the IS250 the clutch sits between the 4GR-FSE V6 and the rear-drive 6-speed manual gearbox, and every bit of torque headed for the rear wheels passes through one disc. The FX100 is the mildest stage Clutch Masters builds. It pairs the Power Plus I heavy-duty pressure plate with a disc faced in steel-backed organic friction material, and Clutch Masters rates it at a 70 percent increase in holding capacity. The maker aims it at street cars with minor bolt-ons such as an intake or exhaust, and describes only slightly more pedal effort than factory, normal engagement feel and longer life than stock.
The D at the end of the part number matters. Clutch Masters builds this dampened-disc version for use with an aftermarket single-mass flywheel, because the springs in the disc hub take over the job of soaking up driveline pulses. If you are keeping the factory flywheel, the matching kit is the rigid-disc 16250-HD00-R.
In fourth gear at about 2,000 rpm, roll into full throttle. If the tach jumps ahead while the car barely gains speed, the disc is slipping. Before blaming the clutch, check the hydraulics: a master or slave cylinder that leaks or does not fully return the pedal can hold the clutch partly released and mimic a worn disc. Look for oil on the bellhousing seam too, since a leaking rear main seal will glaze a new disc quickly. Our slipping diagnosis guide walks through the checks, and the flare vs slip explainer helps you describe what the car is doing. For shudder on takeoff, see clutch chatter causes.
This kit fits the 2006-2012 Lexus IS250 2.5L with the 6-speed manual, matching the Clutch Masters application. In this generation the manual was offered on the rear-wheel-drive IS250 sedan; the IS250 AWD and the IS350 were automatic-only, so they do not use this kit. If you have an IS250 C convertible with a manual, send us your VIN before ordering so we can confirm it. Because this is the dampened disc, plan on fitting a single-mass flywheel such as the Clutch Masters IS250 aluminum flywheel, listed for 2006-2011 cars. Keeping the stock flywheel? Ask us about the FX100 rigid-disc kit, part 16250-HD00-R, instead. More options are in our clutch and rebuild kit collection.

Clutch Masters designs the dampened 16250-HD00-D for an aftermarket single-mass flywheel. If you are reusing the factory flywheel, the rigid-disc 16250-HD00-R is the version built for it.
No. In this generation the manual gearbox was offered on the rear-wheel-drive IS250; the AWD IS250 and the IS350 used automatics and have no clutch kit application.
Yes. Clutch Masters builds the FX100 for street cars with minor bolt-ons and describes only slightly more pedal effort than factory with normal engagement feel.
The IS250 clutch hydraulics share fluid with the brake reservoir. Bleed with fresh brake fluid of the type printed on your reservoir cap after the install.
Fit the flywheel you plan to run, replace the pilot bearing if supplied, inspect the release fork and pivot, and fix any rear main seal leak so oil does not ruin the new disc.
