GSC Power Division Billet S2 Camshaft Set Subaru WRX STI MY08+ Dual AVCS

GSC Power Division Billet S2 Camshaft Set - Subaru WRX STI MY08+ - Dual AVCS

GSC Power Division builds these billet S2 camshafts for serious horsepower Subaru builds, and they're a step up from the milder S1 profile. Designed for the Subaru WRX STI EJ257 with Dual AVCS, the S2 lobe profile is aimed at engines pushing well past stock output, where bigger lift and duration actually get used.

This listing covers the Subaru WRX STI GRF and GVF MY08+ models fitted with the Dual AVCS EJ257 engine. SKU GSC7026S2.

Important: These cams suit builds in the 500whp and up range and require a built motor, ported head with clearance work, and a capable engine management setup to run correctly. Cam placement is long nose left, short nose right — check during install.

Important Installation Notes

• Head castings may need light filing for lobe clearance — check on install
• Proper break in procedure required, run high zinc oil on flat tappet setups
• Installation by an experienced technician only
• Supporting mods required to realise full potential: built engine, ported head, tuned ECU

Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your engine and AVCS configuration before ordering.
