it's now called the HDSS (Heavy Duty Super Street) clutch, and the part # I believe is SB5-HDSS. 06-09 use the same clutch plate and flywheel. I wouldn't resurface the flywheel because it'll be outside of subaru specs. The flywheel I have is designed for drag racing, and street drive-ability. It drives like the stock flywheel, and launches like the stock flywheel, but I did gain gas mileage, and it does rev a little quicker. Also there are no CELs. It's the ACT StreetLight Flywheel.
