GSC Power-Division Billet S3 Camshafts for the USDM STI and WRX with Intake only AVCS. These cams are built to suit the high horsepower drag Subaru's. With a power range of 750-1000 WHP and a rev range of 4500-9500 RPMs, you need some certain mods to utilize the true potential of the S3s: built motor, with a built/ported head (clearance for lift), and an engine management solution. Upgraded valve springs are required; GSC beehive valve springs are recommended, but not required.
Specs:
| 7025S3 | ADV Duration | Duration @ 0.040" | Peak Lift | Center Line |
| Intake | 280° | 240° | 11.55mm | 130° |
| Exhaust | 280° | 241° | 11.60mm | 115° |
GSC Recommendations:
- 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
