ACT 2006 Mitsubishi Lancer XACT Flywheel Prolite
The ACT 600210 is a lightweight chromoly flywheel for the 2003-2006 Mitsubishi Lancer Evolution VIII and IX with the 2.0L turbo 4G63. Owners usually go looking for it when the stock flywheel is heat-checked or due for replacement during a clutch job, or when a track or rally car needs the engine to rev and drop faster between shifts. At 10.1 lb it is the lightest of ACT's XACT flywheel options, and ACT builds it as a race part, so read the trade-offs below before you buy it for a daily driver.
In the Evo the flywheel bolts to the crank, carries the 114-tooth ring gear the starter engages, and gives the clutch disc a flat, heat-tolerant face to clamp against. Its mass also stores rotating energy. Less mass means the engine gains and sheds RPM quicker, so rev-matched downshifts land faster and the turbo engine feels sharper coming off a corner. ACT forges the Prolite from chromoly steel in one piece, CNC machines it, computer balances it and induction-hardens the ring gear, so there is no separate insert to warp and no pressed-on ring gear to come loose. It carries SFI 1.1 certification and can be resurfaced like a stock flywheel.
The cost of that response is drivability. ACT lists the feel as mild to moderate gear rattle and recommends the Prolite for race use. Expect more idle chatter from the gearbox and a little more care pulling away. If the car is mostly driven on the street, ACT's heavier 600205 Streetlite flywheel for the same cars is the better match. Our lightweight vs stock flywheel guide explains the difference in plain terms.
Most Evo flywheel decisions are made with the transfer case and transmission already out for a clutch. Inspect the face for heat cracks that run toward the bolt holes, measure for warp with a dial indicator, and check the ring gear for missing or rounded teeth. Shallow glazing can often be machined out; cracks, deep hot spots and ring gear damage mean replacement. Our resurface vs replace guide covers where that line is. If you are chasing slip and are not sure it is the clutch at all, start with the slipping diagnosis guide.
Our listing is titled for the 2006 Lancer, but ACT's application list for 600210 is the Lancer Evolution only: 2003 and 2004 Evolution, 2005 Evolution, MR and RS, and 2006 Evolution, MR, RS and SE, all with the 2.0L DOHC turbo engine. It does not fit the regular 2.0L Lancer, the Ralliart 2.4L or the 2008 and later Evolution X. ACT specifies a 240 mm (9.4 inch) friction surface and 114 ring gear teeth. ACT also notes that the step, ring gear tooth count, thickness and ring gear offset must match your clutch, so confirm your clutch is a 240 mm single-disc Evo kit that works with a stepped or flat flywheel as required. If you are unsure, send us your year and VIN. More Evo clutch parts are in our hard parts collection.
Common Evo and Lancer gearbox issues that come up during a clutch job are covered in our Lancer transmission problems guide. The flywheel is new, in stock, ships from the USA the same business day and carries a 1-year warranty.

ACT lists it at 10.1 lb. It is a one-piece forged chromoly flywheel with a 240 mm friction surface and 114 ring gear teeth.
ACT recommends the Prolite for race use and lists mild to moderate gear rattle. For a mostly street car, the heavier 600205 Streetlite is the easier choice.
Yes. ACT says its flywheels are serviceable and can be resurfaced with no additional parts needed.
ACT says its flywheels work with good-quality clutches as long as the step, tooth count, thickness and ring gear offset match the application. Confirm your clutch is a 240 mm Evo VIII or IX single-disc kit.
Yes. ACT lists SFI 1.1 for the 600210.
