GSC Power-Division billet S3 camshafts for the 08+ Subaru STi EJ257 with Dual AVCS.
These cams are built to suit the high horsepower drag Subis. With a power range of 750-1000 WHP and a rev range of 4500-9500 RPMs, you need some certain mods to utilize the true potential of the S3s: built motor, with a built/ported head (clearanced for lift), and a standalone engine management system. Upgraded valve springs are required; beehive valve springs are recommended but not required.
Please note that these are for the USDM models with AVCS on intake and exhaust only!
