GSC Power-Division billet S2 camshafts for the USDM STi and WRX with Intake only AVCS. These cams are built to suit the high horsepower Subis. With a power range of 500 WHP and up, you need some certain mods to utilize the true potential of the S2s: built motor, with a built/ported head, and a turbo capable of supporting 500+ WHP. Upgraded valve springs are required; beehive valve springs are recommended, but not required.

  • Check Pictures for cam placement. Long nose = Left Side, short nose = Right Side
  • Due to the lobe size, head castings may need to be filed down slightly for clearance - Please check during install
  • Proper break in and running high zinc oil is a must on flat tappet engines
  • Must be installed by an experienced technician
