Clutch Masters 17-21 Honda Civic Type R 725 PRO Series Twin Disc Clutch w/Steel Flywheel
A tuned 2017-2021 Honda Civic Type R with a bigger turbo, E85 and a flex-fuel map can make far more than the factory 295 lb-ft of torque. Once it does, the stock clutch starts to slip on the 3-4 shift or at full boost in fifth. Clutch Masters part number 08520PTD7RS is the 725 PRO Series Twin Race clutch for the FK8 Type R. It comes with its own billet steel flywheel and an estimated 700 ft-lb torque capacity for built K20C1 street and track cars.
The FK8 pairs the turbocharged K20C1 with a close-ratio six-speed manual and a limited-slip differential, and all of that torque passes through one clutch disc. Rather than a larger single disc, this kit uses two 7.25 inch rigid ceramic discs with a floater plate, giving four friction faces in a compact pack. The smaller pack drops rotating inertia, so the engine falls to the next gear's rpm faster on upshifts.
PTD7R is the Twin Race stage and the trailing S means the steel flywheel is in the box. Clutch Masters redesigned the older FX 725 for the PRO series: twelve heat-treated 4140 steel stands replace six aluminum posts, because the aluminum posts flexed and wore under high-power use. The flywheel is machined from 1045 billet steel and black-oxide coated. Clutch Masters lists the contents as the 7.25 inch PRO clutch pack, an alignment tool, the steel flywheel and a release bearing, and notes the kits are SFI certified and made in the USA. It is a conversion kit and cannot be used with the Honda flywheel.
Datalog a pull in fourth or fifth and compare engine rpm against vehicle speed; a sudden rpm jump as boost peaks is clutch slip. Then rule out the easy causes: air in the clutch hydraulics, a slave that does not fully release, and oil on the disc from a seal leak. Our slipping diagnosis guide explains separating clutch slip from other faults, and the shift flare vs slip guide helps read the log. If you are weighing two discs against a single puck, see the twin vs single disc comparison.
Clutch Masters lists 08520PTD7RS for one application only: the 2017-2021 Honda Civic Type R 2.0L turbo, the FK8 generation. It is not listed for the FK2 Type R sold outside North America, the FL5 Type R that followed, or the Civic Si. If your car has a non-factory transmission or a previous clutch conversion, send us the year and last 7 of the VIN before ordering. A milder option for a mostly street car is the Clutch Masters FX250 single disc for the Type R, and the 725 Series street twin 08520-TD7S-S is the softer multi-disc choice. More kits are in our rebuild kits department.

No. Clutch Masters lists it only for the 2017-2021 FK8 Civic Type R. The newer FL5 is not on the application list.
Clutch Masters estimates 700 ft-lb of torque capacity for the 725 PRO twin, far above the FK8's factory 295 lb-ft, so it suits heavily tuned and big-turbo cars.
No. This is a conversion kit that only works with the Clutch Masters billet steel flywheel included in the box.
It can be driven on the street, but rigid ceramic discs engage quickly and you will hear some rattle at idle. For mostly street driving, a single disc or the 725 street twin is easier to live with.
The kit includes a release bearing. Inspect the fork pivot and flush the clutch fluid while bleeding the system, and fix any seal leak at the bell housing before the new discs go in.
Honda manual transmission fluid in the six-speed, and fresh fluid in the clutch hydraulics when you bleed them.
