GSC Billet Stage 1 Cams - Non AVCS (02-05 WRX)

GSC 7000 Series Full Billet Camshafts are 100% in-house cut and ground on the newest, most precise CNC machines available.  The 7000 Series camshafts take the import valve train market to another level, being the only readily available and affordable billet camshafts for sport compact/import performance cars.

GSC Power-Division Billet S1 camshafts for the EJ205 WRX Version 5 and 6. These will not drop any low end power, but actually cause faster spool of the turbo, creating more power and torque across the entire RPM range. Good for stock turbo or up to 500WHP upgrades. These cams require upgraded valve springs to keep everything safe at high RPM.
