GSC Power-Division S1 camshafts for the USDM 04-07 STi. 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(GT35R) upgrades. These cams require upgraded valve springs to keep everything safe at high rpm.
