240MM EJ20

Technical Parameters

Product Advantage

• S-Metal (Sintered Metal) Friction Disc​

Unique metallic compound provides high and stable coefficient of friction, outstanding heat resistance and long service life under repeated high-load engagement.

• 11,300 N Clamp Load Cover Assembly

Approx. 40% higher clamping force than the genuine cover, dramatically raising torque transmitting capacity and eliminating slip on boosted setups.

• 240 mm Thick-Type Disc​

Increased thermal mass and heat dissipation area resists fade during hard launches, hill climbs and circuit sessions.

• 10% Lower Inertia​

Lightweight metallic disc reduces rotational mass for quicker engine response, faster shifts and reduced synchro load.

• Sprung Hub with Torsion Damper

Absorbs driveline shock and gearbox rattle; protects the transmission during aggressive engagement without sacrificing shift feel.

• Strap-Drive Cover Design

Consistent release characteristics and stable clamp load across the full temperature range.

• Direct OE-Fit Design​

Bolt-on installation using factory mounting points and OE release mechanism; no bellhousing or hydraulic modification required.

• Built for Motorsport, Tolerant on the Street​

Engineered for dirt trial, gymkhana, circuit, drift and rally, yet civil enough for street sports use with a predictable, progressive engagement point.

Product Uses

• Daily-Driven Tuned Street Car (Stage 2–3 EJ20T)

Owners running an upgraded turbo, front-mount intercooler, intake and ECU remap routinely exceed what the OE clutch can hold. The 11,300 N clamp load locks the drivetrain under full boost in third and fourth gear, eliminating the mid-range slip that appears right after a remap. At the same time, the sprung-hub damper keeps engagement progressive enough for traffic, commuting and long-distance touring.

• Weekend Track Days & Circuit Sessions

Repeated hot laps generate sustained heat that glazes an organic disc within a single session. The sintered S-Metal friction material maintains a stable coefficient of friction at high temperature, while the thick-type Ø240 mm construction sheds heat quickly between corners. Expect a consistent pedal feel and bite point lap after lap, with the 10% inertia reduction supporting quicker downshifts and cleaner heel-and-toe rev-matching under braking.

• Drag Racing & Hard Launch

Standing starts place the greatest instantaneous shock load on the clutch. The reinforced cover's 11,300 N clamping force resists slip off the line, and the sintered disc bites hard and predictably once properly bedded in. Heat from back-to-back passes is absorbed by the thick friction facing instead of being transferred into the flywheel. Pair it with a lightweight flywheel and suitable tyres for repeatable 60-foot times.

• Drift & Gymkhana

Clutch-kick initiations and aggressive handbrake transitions demand a disc that tolerates sudden engagement without delaminating. The S-Metal facing is built for exactly this duty, delivering the sharp, on-off bite that drivers rely on to break traction and hold angle. Low rotational inertia lets the engine rev freely between transitions, while the strap-drive cover keeps release behaviour consistent through long, high-rpm practice sessions.

• Rally & Dirt Trial

Gravel stages mix low-speed technical sections with high-speed jumps, landing shocks and constant partial-throttle slip. The sintered metal disc is far more tolerant of contamination and heat cycling than an organic plate, and the reinforced cover maintains clamp load after repeated landings. Mud, dust and water do not cause the grab-then-slip inconsistency that plagues street discs, making the car easier to place on loose surfaces.

• Hill Climb, Autocross & Time Attack

Short, intense runs mean the clutch is fully engaged almost immediately, then subjected to a rapid series of upshifts with no cooling interval. The Ø240 mm thick disc absorbs this thermal spike, while the high clamp load prevents the subtle slip that costs tenths out of every corner. Fast thermal recovery between runs suits events where competitors stage again within minutes, run after run.
