ACT 2006 Mitsubishi Lancer XACT Flywheel Streetlite
The ACT 600205 XACT Streetlite is a 13.1 lb chromoly flywheel for the 2003-2006 Mitsubishi Lancer Evolution VIII and IX with the 2.0L turbo engine. Our listing is labeled 2006 Lancer, but ACT builds this part for the Evolution, not the everyday Lancer sedan. Buyers usually find it during a clutch replacement, when the factory flywheel has hot spots or cracks, or when they want a lighter wheel that still behaves on the street. It is the street-biased choice next to ACT's lighter 10.1 lb Prolite.
The flywheel is bolted to the 4G63 crank and does three jobs at once. It gives the clutch disc a hard, flat surface to grip, carries the ring gear the starter turns, and acts as a rotating weight that smooths out idle and low-speed engagement. ACT forges the Streetlite in one piece from chromoly steel, then CNC machines and dynamically balances it, and induction-hardens the 114-tooth ring gear. The friction face is 240 mm (9.4 in) across and the part is SFI 1.1 certified. ACT calls Streetlite its most durable flywheel line and rates the feel as noticeably quicker engine response with OE to mild gear rattle, so it suits a car that gets driven to work during the week and run hard on weekends.
Make sure the problem really is the clutch first. A slipping clutch shows as rpm climbing in a high gear without matching road speed; our slipping diagnosis guide covers the test. Once the gearbox and transfer case are out, check the face for cracks, measure runout with a dial indicator and inspect the ring gear. ACT allows resurfacing of its own flywheels as long as no more than 0.040 in is removed and the step stays correct. If the old wheel is beyond that, replace it. Our resurface vs replace guide explains the call.
ACT's application table for 600205 lists the 2003 and 2004 Lancer Evolution, the 2005 Evolution, MR and RS, and the 2006 Evolution, MR, RS and SE, all with the 2.0L DOHC turbo engine. It is not listed for the non-turbo Lancer, the Lancer Ralliart or the 2008 and later Evolution X. ACT also points out that a replacement flywheel must match your clutch for step, ring gear tooth count, thickness and ring gear offset, and that some ACT clutches sold as conversion kits must be used only with their matching ACT flywheel. Send us your year and VIN if the car has had driveline changes. More Evo parts are in our hard parts collection.
If the car is a dedicated track build that can live with more gear rattle, compare the lighter ACT 600210 Prolite. Known gearbox issues are in our Lancer transmission problems guide. This flywheel is new, in stock, ships the same business day from the USA and carries a 1-year warranty.

No. ACT lists it only for the 2003-2006 Lancer Evolution with the 2.0L turbo engine, including MR, RS and SE trims. The non-turbo Lancer and Ralliart use different flywheels.
The 13.1 lb Streetlite is ACT's most durable flywheel and is rated for OE to mild gear rattle, so it suits street and weekend use. The 10.1 lb Prolite revs faster but ACT recommends it for race use and it rattles more.
Usually yes, as long as the clutch is a 240 mm single-disc kit for the 2003-2006 Evo and the step, tooth count and offset match. ACT conversion-kit clutches must be paired with their own ACT flywheel.
Yes. ACT says its XACT flywheels can be machined like a stock flywheel, removing no more than 0.040 in and keeping the correct step.
A clutch kit, pilot bearing, release bearing if not in the kit, and fresh gear oil for the transmission and transfer case. Check the rear main seal and the clutch hydraulics while you are in there.
