GSC Power-Division S2 camshafts for the EJ205 WRX Version 5 and 6. These cams are built to suit the high-horsepower Subies. With a power range of 500WHP and up, you need some certain mods to utilize the true potential of the S2s. Built motor, with a built/ported head, and a good engine management system. Beehive valve springs are recommended, but a upgraded single spring kit will do the job under 8000 rpm.
Due to the lobe size, head castings will need to be filled down slightly for clearance.
