Spec 10-12 Chevrolet Camaro 6.2L/05-12 Corvette 6.0L/6.2L/7.0L Stage 3 Clutch Kit (Use w/Factory FW)
The SPEC SC663-2 is a Stage 3 single-disc clutch kit for the LS-powered six-speed manual cars: the Chevrolet Camaro SS 6.2L and the C6 Corvette with the 6.0L LS2, 6.2L LS3 or 7.0L LS7. It is aimed at owners whose stock clutch slips once the car has a cam, heads, long-tube headers or a tune, and who want more clamp without giving up the factory flywheel. The listing title says it plainly: this kit is designed to bolt to the recessed factory flywheel, or to a billet flywheel built to the same pattern.
On these cars the pressure plate bolts to a recessed flywheel, meaning the clutch disc sits down inside a step machined into the flywheel face. That is why an LS clutch built for a flat flywheel will not interchange. SPEC's -2 kits are built for the recessed pattern, so SC663-2 drops onto the stock LS3 or LS7 style flywheel. In the SPEC ladder for these cars, Stage 3 sits above Stage 1 (SC661-2), Stage 2 (SC662-2) and Stage 2+ (SC663H-2), and below Stage 3+ (SC663F-2), Stage 4 (SC664-2) and Stage 5 (SC665-2). Moving up the stages raises torque capacity, but engagement gets firmer and less forgiving in daily driving, so Stage 3 suits a street car that sees real power and the occasional strip day.
A slipping manual clutch does not store a trouble code, so confirm it with a road test before you buy.
Warm the car up, hold fourth gear near 2,500 rpm and go to full throttle. If the tach runs ahead of the speedometer, the disc is slipping. Rule out hydraulics first: check the fluid level and condition, and look for fluid at the bellhousing drain, since a leaking concentric slave can feel like a clutch problem and will soak a new disc. Our slipping diagnosis guide covers the road test, and shift flare vs slip explains how slip differs from other drivetrain symptoms.
The listing covers the 2010-2012 Camaro 6.2L and the 2005-2012 Corvette 6.0L, 6.2L and 7.0L with the manual transmission. SPEC's own application charts go a little wider: 2010-2015 Camaro V8 6.2L and 2005-2013 Corvette LS2, LS3 and LS7, both for use with the recessed OE or a billet flywheel. SPEC also lists the 2004-2007 Cadillac CTS-V and 2008-2010 Pontiac G8 GXP. It is not for the LS1 cars with a flat flywheel or for automatic cars, and SPEC does not list it for the supercharged ZL1. The listing shows a single fitment line, so send us your year and VIN if your car has a swapped or aftermarket flywheel. For a softer replacement on a stock Camaro, see the Exedy Stage 1 kit with the hydraulic slave.

Yes. SPEC builds SC663-2 for the recessed OE flywheel or a billet flywheel modeled after it. Have the stock flywheel resurfaced correctly before installing the new clutch.
Our listing names 2010-2012, but SPEC's application chart lists SC663-2 for the 2010-2015 Camaro V8 6.2L manual. Send us your VIN and we will confirm before it ships.
Not the LS1 cars, which use a flat flywheel. SPEC does not list the supercharged ZL1 for this kit either. It is built for the recessed-flywheel LS2, LS3 and LS7 cars.
No. SPEC lists the concentric hydraulic release bearing and slave assembly as a separate part. Inspect yours while the transmission is out.
It is the middle of the range, above Stage 1, 2 and 2+, below Stage 3+, 4 and 5. Higher stages hold more torque with firmer, less forgiving engagement.
