ACT 2015 Mitsubishi Lancer HD-M/Perf Street Sprung Clutch Kit
ACT ME3-HDSS is the street-friendly clutch upgrade for the Mitsubishi Lancer Evolution X with the 2.0L 4B11T turbo engine and five-speed manual. Our listing title says 2015 Lancer, but the kit is for the Evolution, not the standard Lancer. It fits the owner whose GSR or Final Edition now slips at full boost after a tune, or whose factory clutch is simply worn, and who wants smooth everyday engagement instead of a ceramic race disc.
The Evo X clutch is a pull-type design: the release bearing pulls the diaphragm fingers outward to disengage. ACT's kit contains the MB018 Heavy Duty pressure plate, the 3000305 Performance Street sprung disc, the RB602 release bearing and the AT03 alignment tool, with ACT's Monoloc retaining ring. A flywheel is not included.
Monoloc is the part that matters most on this car. The factory setup locks the bearing to the plate with a two-piece wedge collar and wire ring. ACT replaces that with a one-piece hardened chromoly segmented ring whose spring tension is set to load the bearing and plate evenly, keeping them aligned under hard shifts. ACT credits it with a dramatic improvement in release mechanism life.
The rest of the kit is about holding power with stock-like manners. ACT rates it at 530 ft-lb at the crank, 45 percent over the factory clutch, using a 9.4 in (240 mm) organic disc on a 1 in input shaft. The high-copper, steel-backed lining and sprung hub give light to moderate pedal effort, smooth positive engagement and OE to mild gear rattle. Owners who launch hard or run track days at higher power should look at the ME3-HDG6, which uses the same plate with a ceramic six-pad disc rated 678 ft-lb.
Check fluid level and bleed the hydraulics before blaming the clutch, since air in the line causes drag and hard shifts that feel like clutch failure. Then log a fourth-gear pull from around 3,000 rpm at full throttle; if engine rpm climbs faster than wheel speed, the disc is slipping. Our slipping diagnosis guide goes through the test, and shift flare vs. slip helps sort slip from other drivetrain feel. Inspect the bellhousing seam for oil, as a leaking rear main or input seal will ruin a new disc.
ACT lists ME3-HDSS for the 2008-2015 Lancer Evolution GSR, the 2009 Evolution RS, the 2014 Evolution and the 2015 Evolution Final Edition, all with the 1998 cc turbocharged engine and five-speed manual. The twin-clutch Evolution MR, the base Lancer, the Lancer GTS and the Ralliart are not on that chart. ACT sells several ME3 kits with different discs, so match the part number ME3-HDSS to what you need, or send us your year and VIN and we will confirm it before it ships.

Both use the MB018 Heavy Duty plate and Monoloc. HDSS has an organic street disc with smooth engagement and a 530 ft-lb rating; HDG6 has a ceramic six-pad race disc with aggressive engagement and a 678 ft-lb rating.
The flywheel must at least be resurfaced. ACT offers the 600550 Streetlite and 600555 Prolite flywheels for the Evo X if you want a lighter replacement.
