7.25″ (184mm) Honda K20 Clutch

7.25″ (184mm) Honda K20 Clutch


We have built this clutch to suit K20 and K24 powered FWD Competition cars using the OEM gearbox, from standard casings to the Quaife Sequential alternative.

The spec we have used for this application will suit both race and rally, we have opted for .105″ (2.67mm) disc thickness due to the compact nature of the OEM gearbox/input shaft, this coupled with PTT’s legendary high quality manufacturing processes makes this clutch virtually impossible to beat for the application.

FWD applications can be a challenging installation to fit a Twin Disc Competition clutch into due to the limited space available, however the PTT range of clutches are renowned for having one of the most compact clutch cover assemblies in the industry.

We recommend for all installations that a Hydraulic release mechanism (slave cylinder) is used, most K20 OEM gearboxes use an external slave cylinder but an internal concentric is a favoured option.

We have put this together as a pre-defined spec to aid you during the buying experience, simply select your engine/car type from the drop down menu and purchase.

Power V-Drive System: The angled Power-V drive legs make the floater plates self-centring. It evens out the drive forces in the Clutch and provides for inherent dynamic balance. The resulting increased surface area of the Power-V lowers stress in the clutch as well, allowing longer life of component parts.

PTT Proprietary friction materials are state of the art giving smoother engagement characteristics and longer life.

Micro finished friction material means no bedding-in required and eliminates excessive Clutch wear.

Much lower Moment of Inertia than a stock style clutch and up to 20% lower than other manufacturers’ equivalent racing clutches. This lower M.O.I. allows faster acceleration, decreased Brake wear on deceleration, quicker shifting, and reduced Syncro or Dog Ring wear in your Transmission.

Clutch Cover machined from Billet Aluminium. Optimized Clutch Cover design means lower pedal effort, better modulation, driveability and control.

Open housing design means better cooling and dust evacuation.

Fits into a smaller area due to improved design and flush mounted fasteners. Approximately 0.250” shorter overall than competitors clutches.

Tailored to your every element of YOUR application requirements.

Precision manufactured in the USA.
