Technical Parameters

Product Advantage

• Precision Fitment for EVO VIII CT9A 4G63T

TORNADO Stage 2 Sports clutch kit MK04TA is engineered as a direct bolt-on replacement for the Mitsubishi Lancer Evolution VIII (CT9A) 2.0L 4G63T turbo. The 240 mm disc and pull-type release mechanism replicate original equipment geometry exactly, so no bellhousing machining, custom flywheel or hydraulic modification is required. Every unit is dimensionally checked before shipment, guaranteeing a true drop-in installation.

• Race-Proven 660 Nm Torque Capacity

This Stage 2 cerametallic clutch kit is rated at 490 lb.ft / 660 Nm of torque at the flywheel and 400 lb.ft / 530 Nm at the wheels — around 40% more holding capacity than the factory Evo 8 assembly. That margin lets your EVO VIII CT9A 4G63T run a bigger turbo, higher boost, upgraded injectors and a full remap without clutch slip in third or fourth gear. Ideal for 400–500 whp street and track builds.

• Heavy-Duty Cover with 40% Higher Clamp Load

The TORNADO single-series cover uses ductile pressure plate material and a re-engineered diaphragm to deliver approximately 40% higher clamp load than the genuine Mitsubishi part. Burst strength is maintained across the full temperature range, resisting distortion during repeated launches and high-rpm shifts. The result is consistent pedal feel, no fade during long track sessions, and stable release travel after thousands of heat cycles.

• S-Type Cerametallic Disc, Heat Resistant and Fade Free

Unlike organic facings that glaze and slip when hot, the TORNADO Stage 2 disc uses a low-density, carbon-rich cerametallic friction compound. Cerametallic material holds its friction coefficient at temperatures that destroy a stock facing, resists glazing and sheds heat quickly. The paddle design clears friction debris, extending service life under hard street driving, drifting and repeated drag-strip launches.

• Sprung Hub Damper with 10% Lower Inertia

The sprung centre damper absorbs torsional shock before it reaches the gearbox, protecting synchronisers, driveshafts and the transfer case — the classic failure point on hard-launched Evolution drivetrains. Meanwhile the lightweight metallic construction cuts rotating inertia by about 10% versus the OE disc, so the 4G63T revs faster, throttle response sharpens and gear changes feel noticeably quicker, without ruining daily drivability.

• Complete Kit, Street to Rally

Each MK04T601 kit ships complete with pressure plate, cerametallic sprung disc, release bearing and alignment tool — nothing else to buy. It performs equally well on the road, track day, circuit racing, time attack, drifting, drag racing and rally. Recommended break-in is 500 km / 300 miles of gentle driving before full-throttle launches.

Product Uses

• Daily-Driven EVO VIII on the Street

Owners running a stock-turbo or mild Stage 1 Evo 8 will appreciate how forgiving this kit is in traffic. The sprung hub damper absorbs the torsional spike that makes rigid discs chatter and buck at low speed, so pulling away from lights, creeping in queues and parking maneuvers stay smooth. Pedal effort rises only slightly over the genuine clutch, which matters when the CT9A is your everyday car. The 660 Nm ceiling simply means headroom you are not using — insurance against slip on a cold, damp morning.

• Fast Road and Canyon Driving

For spirited back-road runs where the 4G63T sees sustained boost through repeated third and fourth gear pulls, an organic facing starts to glaze and slip. The cerametallic disc holds its friction coefficient as temperatures climb, giving consistent bite on long climbs and descents. The lighter disc sharpens throttle response during heel-and-toe downshifts, and the 240 mm pull-type assembly keeps release travel predictable when you are shifting hard and often.

• Track Day and Time Attack

Circuit sessions punish a clutch far harder than the road ever does: heat soak from repeated laps, high-rpm shifts under full load, and no cooldown between runs. The heavy-duty cover's 40% higher clamp load resists the distortion that causes pedal fade lap after lap, while the paddle disc clears friction debris instead of trapping it. Consistent engagement point throughout a 20-minute session is what lets you focus on braking markers rather than clutch feel.

• Drag Strip and Launch-Focused Builds

Launching an AWD Evolution at 5,500 rpm dumps enormous shock into the drivetrain, and this is where standard clutches slip or shatter. The cerametallic facing takes the initial hit without glazing, and the sprung centre cushions the impact travelling into gearbox, transfer case and driveshafts — the parts that actually break on hard launches. Run it with sticky tyres and a two-step and the MK04TA​ will hold repeated passes without needing cooldown between runs.

• Drifting

Sustained clutch kicks and deliberate slip demand heat tolerance above all else, and that is exactly where cerametallic material outperforms organic. The disc keeps biting through long tandem runs instead of fading mid-corner, and the low-inertia design lets the engine flare instantly for initiation and transitions. Sprung damping also protects the driveline from the violent load reversals typical of clutch-kick entries. Expect faster wear than street use — that is the trade for consistency.

• Rally, Autocross and Hill Climb

Frequent standing starts, gravel-surface wheelspin and constant modulation on loose ground generate heat and abrasion that destroy a stock facing quickly. The reinforced cover and metal-based disc handle repeated abuse with stable pedal feel, and the pull-type mechanism stays reliable through the vibration and contamination of rally stages. Suitable for club-level rally, autocross and hill climb where a full Group N competition clutch would be unnecessarily harsh and expensive.
