ACT 08-17 Mitsubishi Lancer GT / GTS HD/Race Sprung 6 Pad Clutch Kit
The ACT MB11-HDG6 is a race-oriented clutch for the non-Evolution Mitsubishi Lancer with a manual gearbox, covering the 2008-2017 cars with the 2.0L 4B11 and the 2.4L 4B12 in GT and GTS trims. Owners look for it after adding a turbo kit or supercharger, or after cooking a stock or street clutch at the drag strip. It pairs ACT's Heavy Duty pressure plate with a six-pad ceramic race disc, so it holds a lot of torque in exchange for a sharper engagement.
The Heavy Duty pressure plate uses ACT's own diaphragm design to raise clamp load and cut deflection while keeping pedal effort in the light-to-moderate range. ACT says its Heavy Duty plates typically add 15 to 40 percent pedal effort over stock. The disc is a 228 mm (9 in) six-pad ceramic race disc on a spring-centered hub. The springs damp torsional vibration and protect the gearbox on hard shifts, while the six separate ceramic pads shed heat that would glaze a full-face organic lining.
ACT rates the complete MB11-HDG6 at 354 ft-lb at the crank, 87 percent over the factory clutch. For a naturally aspirated Lancer that is far more than needed; it makes sense when boost has pushed torque well past stock. ACT describes the feel as aggressive engagement with OE to mild gear rattle, recommended for high-horsepower street or race use.
A slipping manual clutch will not set a trouble code, so road test it. Select fourth at about 2,500 rpm and go to full throttle; if the tachometer runs ahead of the speedometer, the disc is slipping. Check the clutch hydraulics first, since a soft pedal or a leaking slave cylinder causes poor release rather than slip, and look for oil at the bellhousing that could contaminate the disc. Our slipping diagnosis guide explains the load test and flare versus slip covers how to read what you feel.
Our listing covers the 2008-2017 Mitsubishi Lancer GT and GTS. ACT's application list is wider: 2008-2017 Lancer DE, ES, GT, GTS and SE with the 2.0L 4B11, and 2009-2017 Lancer GT and GTS with the 2.4L 4B12. It does not fit the Lancer Evolution X or Ralliart, which use different turbocharged drivetrains, and it does not apply to CVT cars. The disc takes a 1 in input shaft. If the car has had a gearbox swap, send us the year and VIN before ordering.

No. ACT lists it for the 2008-2017 Lancer 2.0L 4B11 (DE, ES, GT, GTS, SE) and 2009-2017 Lancer 2.4L 4B12 (GT, GTS) with a manual gearbox.
ACT rates the kit at 354 ft-lb measured at the crank, 87 percent more than the factory clutch.
Yes. The kit includes the MB025 pressure plate, 6224704 six-pad sprung disc, AT20 alignment tool, RB013 release bearing and the pressure plate bolts.
Engagement is more aggressive than an organic clutch, as with any six-pad race disc, but ACT rates pedal effort as light to moderate. If the car is mostly a commuter, the MB11-HDSS street kit is the smoother choice.
No flywheel is included and none is required, but the factory flywheel should be resurfaced or replaced if it is scored or heat-spotted.
ACT says race discs usually need only a few hard slips to lap in the surfaces before normal driving, and warns not to overheat the clutch during break-in.
