GSC Power-Division Evolution 4-8 S1 CamshaftsThe GSC Power Division S1 cams for the Mitsu Evolution 4 8 are designed for those with the stock turbo up to the GT30 50Trim.

Gains of 30 55whp (depending on Turbo) have been seen by simply bolting the S1 cams in. Designed for a rev range of 3000 8000rpms, these cams work well on the stock valve springs. 300

Warm and handy!
Size: 7-9.5, Color: Black Lattice
Bought these for my husband to wear while he races on his racing simulator. He likes that they are very warm while still being thin enough he can feel the pedals!
