ACT's 600120 Streetlite is an 11.8 lb forged chromoly steel flywheel with a 212 mm friction face. On an early car with the original 200 mm clutch, you'll need the matching 212 mm clutch conversion as well. The flywheel alone won't convert the clutch.\u003c\/p\u003e\n\u003ch3\u003eStreetlite for a D-series you still drive\u003c\/h3\u003e\n\u003cp\u003eFor a Civic or CRX that has to do the commute as well as a day at the strip, we'd put Streetlite on the shortlist. ACT favors this design for street or drag racing and recommends it for both street and race use. Our advice is to choose the disc around the car's torque and the way you'll drive it. If a street disc meets those needs, keep it in the plan; this flywheel doesn't require a race disc.\u003c\/p\u003e\n\u003cp\u003eA lighter flywheel lets your engine gain and lose revs more quickly. It stores less rotational energy, so you'll have less of that energy helping with takeoff. That's the trade-off to consider alongside the disc's engagement. We wouldn't choose a rigid ceramic race disc for a commuter simply because it fits the 212 mm face. You'll live with the disc's takeup every time you pull away, not just when you use the car at the strip.\u003c\/p\u003e\n\u003cp\u003eACT rates gear rattle for 600120 as OE to mild. In its technical bulletin, ACT calls the noise a \"light knocking or growling sound.\" You may hear it with the car idling in neutral after a long drive or on a hot day. That's the gear teeth separating and contacting as engine pulses reach the gearbox. You'll dampen those pulses with a sprung disc; a rigid hub and lighter rotating parts can let you hear more gear noise.\u003c\/p\u003e\n\u003cp\u003eIf the car shudders as you bring the clutch in, you're dealing with chatter rather than the noise ACT describes. Check a new noise or vibration on your car before writing it off as gear rattle. ACT doesn't accept increased gear rattle as a warranty defect, so noise tolerance belongs in the clutch-and-flywheel decision.\u003c\/p\u003e\n\u003ch3\u003eChromoly steel and later servicing\u003c\/h3\u003e\n\u003cp\u003eThe one-piece steel construction is a reason to choose this part beyond its weight. At the next clutch change, you can have the face resurfaced within ACT's limits; you won't need a separate friction insert. If you're comparing it with an aluminum flywheel that uses an insert, include that servicing difference in the decision. ACT makes 600120's friction face and ring gear in one piece and describes uniform heat transfer from the disc as a benefit.\u003c\/p\u003e\n\u003cp\u003eACT uses a heat-treated chromoly forging for strength and toughness. It CNC machines and dynamically balances the flywheel, and induction-hardens the ring gear for wear resistance. You aren't choosing steel solely because it can be resurfaced; the material, heat treatment and one-piece layout are part of the design. You'll still need to keep the correct step and stay within the machining limit below. ACT lists SFI 1.1 for 600120.\u003c\/p\u003e\n\u003ctable\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eSKU \/ ACT part number\u003c\/td\u003e\n            \u003ctd\u003eact600120 \/ 600120\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eFlywheel type\u003c\/td\u003e\n            \u003ctd\u003eXACT Streetlite\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eFlywheel weight\u003c\/td\u003e\n            \u003ctd\u003e11.8 lb\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eMaterial\u003c\/td\u003e\n            \u003ctd\u003eForged, heat-treated chromoly steel\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eConstruction\u003c\/td\u003e\n            \u003ctd\u003eOne piece, CNC machined and dynamically balanced\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eFriction surface\u003c\/td\u003e\n            \u003ctd\u003e212 mm \/ 8.3 in\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eRing gear\u003c\/td\u003e\n            \u003ctd\u003e109 teeth, induction hardened\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eSFI specification listed by ACT\u003c\/td\u003e\n            \u003ctd\u003e1.1\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003ePair the early conversion with the right transmission\u003c\/h3\u003e\n\u003cp\u003eSay you've got a 1989 CRX with the original 200 mm clutch.

Don't lose the wagon detail when you order the clutch.\u003c\/p\u003e\n\u003cp\u003eFor that 1989 CRX conversion, HC4-HDSS is one street-disc example to compare. ACT lists 235 lb-ft at the crank for that kit. If your engine's torque is within the kit's rating and you want a street-disc setup, you can pair it with 600120 without choosing a rigid race disc. The HC4-HDR4 and HC4-HDR6 race kits are rated at 300 lb-ft, but their rigid ceramic discs bring aggressive engagement and more gear rattle. We'd choose between those setups on the car's torque and use, not on the higher rating alone. Those figures belong to the clutch kits; they aren't a torque rating for this flywheel.\u003c\/p\u003e\n\n\u003ctable\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eYears\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e\u003cstrong\u003eMake \/ Model\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e\u003cstrong\u003eApplication notes\u003c\/strong\u003e\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1988-1991\u003c\/td\u003e\n            \u003ctd\u003eHonda Civic \/ CRX\u003c\/td\u003e\n            \u003ctd\u003e1.5L \/ 1.6L SOHC manuals; original 200 mm clutch in 1988-1989 requires the matching 212 mm conversion\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1992-2000\u003c\/td\u003e\n            \u003ctd\u003eHonda Civic\u003c\/td\u003e\n            \u003ctd\u003eD-series SOHC manual trims; not B16 DOHC Si\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2001-2005\u003c\/td\u003e\n            \u003ctd\u003eHonda Civic\u003c\/td\u003e\n            \u003ctd\u003eD17 SOHC manual trims; not K20 DOHC Si\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1993-1997\u003c\/td\u003e\n            \u003ctd\u003eHonda Civic del Sol\u003c\/td\u003e\n            \u003ctd\u003eSOHC S \/ Si, manual; excludes B16 VTEC\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1997-2005\u003c\/td\u003e\n            \u003ctd\u003eAcura EL\u003c\/td\u003e\n            \u003ctd\u003eSOHC, manual\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eFor a del Sol, you'll use the SOHC S or Si application, not the B16 VTEC model.

Automatic and CVT setups aren't covered.\u003c\/p\u003e\n\u003cp\u003eDon't let the matching flywheel number make the rest of the clutch order for you. In ACT's HC4 and HC5 families, you'll find the H023 plate and matching disc numbers in some kits, but different release bearings: RB427 in HC4 and RB820 in HC5. Choose the kit for your release system. That matters just as much as getting the flywheel application right.\u003c\/p\u003e\n\u003ch3\u003eWhat you'll need for the job\u003c\/h3\u003e\n\u003cp\u003eYou'll get one flywheel, with the clutch purchased separately. ACT calls for new factory flywheel bolts; confirm your bolt supply before starting, since inclusion isn't verified for this listing. Use your factory service manual for torque specifications. Check the flywheel's marked number, dowels and SFI label before fitting it.\u003c\/p\u003e\n\u003cp\u003eYou've already done the work to get the gearbox out. Take that access seriously: check the cable or hydraulics, fork, pivots, guide tube and seals before you put it back. Fix any oil leak you find. Oil on the friction faces can cause slip or judder, and a new flywheel won't cure the leak.\u003c\/p\u003e\n\u003cp\u003eTry the disc on the input shaft while it's accessible. It needs to fit and slide, and the pressure plate needs to locate on the flywheel's dowels. Check both before you start refitting the gearbox. Keep ACT's instructions and the factory procedure beside you for the full assembly and release adjustment.\u003c\/p\u003e\n\u003cp\u003eIf you're having it resurfaced later, take ACT's limits to the machinist with the flywheel. You'll need a flywheel grinder used on the face, with only enough material removed to clean it up. ACT sets the limit at 0.040 in \/ 1.02 mm. Keep the correct step between the friction face and pressure-plate mounting face; you're preserving the clutch's working geometry as well as cleaning its contact surface. Don't count the limit as another 0.040 in you can remove at every clutch change.\u003c\/p\u003e\n\u003cp\u003eYou'll have ACT's listed 12-month limited warranty for material and workmanship defects under its published terms. Keep the receipt from your authorized dealer with the flywheel's paperwork. You'll need it for a claim, and you'll want to check the current terms before returning a part. ACT excludes installation labor. 600120 also carries ACT's California Proposition 65 warning.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003ctable\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eYears\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e\u003cstrong\u003eMake \/ Model\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e\u003cstrong\u003eApplication notes\u003c\/strong\u003e\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1988-1991\u003c\/td\u003e\n            \u003ctd\u003eHonda Civic \/ CRX\u003c\/td\u003e\n            \u003ctd\u003e1.5L \/ 1.6L SOHC manuals; original 200 mm clutch in 1988-1989 requires the matching 212 mm conversion\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1992-2000\u003c\/td\u003e\n            \u003ctd\u003eHonda Civic\u003c\/td\u003e\n            \u003ctd\u003eD-series SOHC manual trims; not B16 DOHC Si\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2001-2005\u003c\/td\u003e\n            \u003ctd\u003eHonda Civic\u003c\/td\u003e\n            \u003ctd\u003eD17 SOHC manual trims; not K20 DOHC Si\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1993-1997\u003c\/td\u003e\n            \u003ctd\u003eHonda Civic del Sol\u003c\/td\u003e\n            \u003ctd\u003eSOHC S \/ Si, manual; excludes B16 VTEC\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1997-2005\u003c\/td\u003e\n            \u003ctd\u003eAcura EL\u003c\/td\u003e\n            \u003ctd\u003eSOHC, manual\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e \n\u003c\/li\u003e\n\n\n\n\n\n\n \n\u003cli id=\"Included\"\u003e\n\u003cp\u003eOne ACT 600120 flywheel.
