E46 M3 Schrick 296 Degree Exhaust Camshaft with 14.0mm valve lift. This is only for use in professionally-built E46 M3 race engines. Schrick has developed this ultra-aggressive S54 race cam with 296-deg duration and 14mm of valve lift. Because of the aggressive profile and specs of this cam, Schrick only recommends it be used with no VAN0S or with special custom pistons with deep valve reliefs. We strongly recommend this be professionally installed by an experienced engine builder to check clearances and fitment.

Schrick also requires valvetrain hardware to go along with this cam:
Schrick valve springs
Schrick rocker arms
Schrick upper and lower retainers
