        A:  GSC recommends beehive springs, but they are not required, as long as you do upgrade your valve springs. Give us a call and we can help you find the perfect parts for your power goals.

    • Q: 2006 WRX fitment  mason.davies.usn278094 years ago

      According to the GSC Website, these are designed for all EJ25s with intake AVCS. I dont see any S1 grind cams for the EJ25. Is it possible that there is some sort of error with the fitment list? I would really like S1 cams for my 2006 WRX

        A:  These are listed as fitting with AVCS
