GSC Power Division S3 Billet Performance Camshaft Kit EJ20/205 Non VVT 1999+

GSC Power-Division billet S3 camshafts for the EJ205 WRX Version 5 and 6. These cams are built to suit the high horsepower Subis. With a power range of 700 WHP and up, you need some certain mods to utilize the true potential of the S3s: built motor, with a built/ported head, and a good engine management system. Upgraded valve springs are required; beehive valve springs are recommended, but not required.
