Spec 07-09 Pontiac Solstice 2.0T Aluminum Flywheel
SPEC SC40A-2 is a billet aluminum single-mass flywheel for the turbocharged Kappa roadsters: the Pontiac Solstice GXP and Saturn Sky Redline with the 2.0L Ecotec LNF and five-speed Aisin AR5 manual, plus the Opel GT. Our listing reads 2007-2009 Solstice 2.0T; SPEC lists the Solstice GXP and Sky Redline for 2007-2010 and the Opel GT for 2007-2009. Most buyers are building a GXP or Redline past stock power and are fitting a SPEC clutch, because SPEC designs its clutches for these cars around this flywheel.
The LNF makes 260 hp and 260 lb-ft from the factory, and tuned cars make a good deal more. The flywheel bolts to the crank, carries the starter ring gear, and is the surface the clutch disc clamps against. SC40A-2 cuts rotating mass, so the turbo four builds revs faster between gears and drops them faster for heel-toe downshifts. It is also the mounting base for SPEC's own clutches: SPEC describes its GXP and Redline clutches as a proprietary non-ratcheting design for use only with this billet single-mass flywheel. Before you go lighter, read our lightweight vs stock flywheel guide so the change in launch feel is no surprise.
Do a road test first: in fourth gear at low rpm, go to full boost and watch the tach. If engine speed jumps without the car pulling harder, the clutch is slipping. Our clutch slipping guide covers that test, and the clutch chatter guide separates a glazed flywheel from worn mounts or a contaminated disc. A low or soft pedal points to the hydraulics, not the flywheel, and our slipping diagnosis walkthrough shows how to log rpm against road speed if the symptom is hard to pin down. If you are still choosing a clutch to go with it, the clutch kit buyers guide explains street versus stage ratings.
SPEC lists SC40A-2 for the 2007-2010 Pontiac Solstice GXP, the 2007-2010 Saturn Sky Redline, and the 2007-2009 Opel GT roadster, all with the 2.0L turbo and manual gearbox. It does not fit the base 2.4L Solstice or Sky, and cars with the 5L40-E automatic use a flexplate. Plan to pair it with one of SPEC's non-ratcheting clutches for these cars, such as the SC401-2 Stage 1; SPEC says those clutches work only with its billet flywheel. Compare your old flywheel's bolt pattern and ring gear, or send us the year and VIN and we will confirm. More parts are in our hard parts collection.
SPEC's listing shows a 12 lb weight for SC40A-2. It is new, in stock, ships from the USA the same business day, and carries a 1-year warranty.
