ACT 23-26 Toyota GR Corolla XACT Flywheel Streetlite
ACT 601510 is a forged chromoly XACT Streetlite flywheel for the 2023-2026 Toyota GR Corolla and its 1.6L three-cylinder turbo G16E-GTS. GR Corolla owners usually reach for it at clutch time: the transmission is already out, the factory clutch is slipping or being upgraded, and a lighter, resurfaceable one-piece flywheel makes sense. It is also for drivers chasing quicker revs between shifts on the street, at the drag strip or on an autocross course.
The flywheel is the friction surface the clutch disc clamps against and the carrier for the starter ring gear. ACT machines 601510 from a heat-treated forging, weighs it at 15.5 lb, and gives it a 240 mm (9.4 in) friction face with a 117-tooth induction-hardened ring gear. ACT calls Streetlite its most durable flywheel line: lighter than stock for better response, but with enough mass kept to stay drivable. ACT lists the feel as noticeably improved engine response and acceleration with OE to mild gear rattle, and recommends it for street and race use. It carries SFI 1.1 certification, which matters if the car runs at tracks that check.
Because it is one piece, there are no inserts to warp and no pressed-on ring gear to walk loose. ACT notes the flywheel can be used with either the OEM GR Corolla clutch or an ACT clutch kit, so you are not forced into a full clutch package to run it.
Most flywheel problems are found with the transmission out, so inspect the old face for heat checking, hard spots and runout when you pull the clutch. If you are still deciding whether the clutch is slipping at all, do a loaded test in a high gear and compare rpm with road speed, as our slipping diagnosis guide describes. Our flare versus slip guide helps sort out what you are feeling, and the clutch chatter page covers takeoff shudder from a warped or glazed surface.
ACT lists 601510 for the 2023-2026 Toyota GR Corolla with the 1.6L turbo G16E-GTS, covering Core, Premium, Premium Plus, Circuit Edition and Morizo Edition trims, plus the 2021-2023 and 2025-2026 GR Yaris that shares the engine. It is not for the regular Corolla. Flywheel step, thickness and ring gear count all have to match your clutch, so if you are pairing it with a non-ACT aftermarket kit, confirm with that clutch maker that it works with a stock-spec flywheel. Send us your year and VIN with any doubt and we will confirm before it ships. More GR Corolla clutches are in our clutch and rebuild kit collection.
Clean the crankshaft flange and threads, install the flywheel with new bolts torqued in sequence to the factory spec, and check runout before the clutch goes on. Wipe the friction face with brake cleaner to remove the protective film. Replace the pilot bearing if the car uses one and fit a new release bearing at the same time. If the OEM clutch is worn, this is the moment to replace it; GR Corolla upgrades we carry include the FX100 street kit and the FX350 kit for more power. When the flywheel eventually needs service, ACT says it can be resurfaced like a stock unit, but remove no more than 0.040 in and keep the correct step height.

Yes. ACT states this flywheel can be used with the OEM clutch kit or an ACT clutch kit. If you plan to use another brand's aftermarket clutch, confirm with that maker that their kit works with a stock-dimension flywheel.
ACT lists it at 15.5 lb. It is a forged, CNC-machined chromoly steel flywheel with a 240 mm friction surface and a 117-tooth ring gear.
ACT lists 601510 for the 2021-2023 and 2025-2026 GR Yaris with the same 1.6L G16E-GTS engine, as well as the 2023-2026 GR Corolla. It does not fit the standard Corolla.
ACT rates the Streetlite feel as OE to mild gear rattle, so some owners hear a little more at idle. It is the more streetable of ACT's lightweight lines compared with Prolite.
Yes. ACT says XACT flywheels resurface like stock flywheels. Remove only enough to clean up the face, never more than 0.040 in, and keep the step height correct.
Use new flywheel bolts, a new release bearing and pilot bearing where fitted, and replace the clutch disc and pressure plate if they are worn. Refill or top off the transmission with the factory-specified gear oil if it was drained.
