ACT 2003 Mitsubishi Lancer XT-M/Perf Street Sprung Clutch Kit
ACT ME2-XTSS is an Xtreme street clutch kit for the Mitsubishi Lancer Evolution VIII and IX with the 4G63T 2.0L turbo. Our listing is filed under the 2003 Lancer, which in ACT's chart means the 2003 Evo VIII. It is aimed at tuned Evos where boost and torque have outgrown the factory clutch: slip in third and fourth under full boost, a high engagement point, or a stock clutch that has been launched one too many times.
The kit pairs ACT's MB018X Xtreme pressure plate with the 3000305 Performance Street sprung disc. ACT rates it at 615 ft-lb at the crank, 68 percent over the original clutch. The organic disc is 240 mm (9.4 in) on a 1 in input shaft, with a copper-rich lining for heat transfer and a steel backing for burst strength. Because it is organic and sprung, it engages smoothly enough for a daily driven car while the Xtreme diaphragm supplies the clamp load a built 4G63 needs.
The Evo uses a pull-type release system, and this kit includes ACT's Monoloc, a one-piece hardened chromoly replacement for the factory two-piece wedge collar and wire ring that holds the release bearing to the pressure plate. ACT says it keeps the bearing loaded evenly and aligned, which addresses a known weak point of pull-type clutches. Kit contents are the MB018X plate, 3000305 disc, RB601 release bearing, AT03 alignment tool and the Monoloc. ACT lists the kit at 17.4 lb.
Rule out the hydraulics and the release mechanism first. A leaking slave cylinder or air in the line causes poor release, and a pedal that goes to the floor with no resistance often means the pull-type release bearing has come off its collar rather than a worn disc. For slip, do a full-boost roll-on in fourth from low rpm and watch whether the tach rises ahead of speed. Our slipping diagnosis guide walks through the test, and flare vs. slip helps pin down what you are feeling.
ACT lists ME2-XTSS for the 2003 to 2005 Lancer Evolution VIII and the 2006 Evolution IX with the 4G63T, five- and six-speed, including the MR, RS and SE trims. It does not fit the non-Evo Lancer, the Evo X with the 4B11T or earlier Evos. Because our listing is labeled for the 2003 car, send us the year, trim and VIN if you have a 2004 to 2006 car and want confirmation before it ships. More clutch parts are in our rebuild kits category.
No flywheel is included. ACT offers two chromoly flywheels for these cars: the 600205 XACT Streetlite (240 mm, 114-tooth ring gear) and the lighter 600210 XACT Prolite. If the car is closer to stock, the ME2-HDSS Heavy Duty kit gives a lighter pedal.

Yes, it is included. Monoloc is ACT's one-piece chromoly replacement for the factory two-piece wedge collar and wire ring on pull-type clutches, keeping the release bearing aligned and evenly loaded.
No. ACT offers the 600205 Streetlite and 600210 Prolite flywheels for these cars, or you can resurface a healthy stock flywheel.
ACT describes moderate to heavy pedal effort and says Xtreme plates generally add 50 to 80 percent over stock. For a lighter pedal on a mildly modified car, look at ME2-HDSS.
Yes. ACT recommends 300 to 500 miles of mild driving on organic street discs before racing or hard launches.
