These are the GSC billet core camshafts built to suit the high horsepower Subaru WRX/STI’s from 2008 and on. If you have a highly built motor that consists of a larger turbocharger, and are making more than 500WHP, then the GSC billet core will help you in the top-end gains. The intake cams are 272 10.7mm, while the exhaust camshafts are 272 10.4mm.
Upgraded valve springs are required, and proper break in running high zinc oil is a must on flat tapped engines. Must be installed by an experienced technician.
