Schrick has been dedicated to engine performance through the development of only the highest quality camshafts for more than 40 years. They've created a bond with BMW enthusiast nearly the entire time, offering options for both the street and track using top materials for strength and accuracy. Schrick has grown into a technology center offering one of the most advanced locations for engine testing and manufacturing.

46 M3 Schrick high-performance racing camshaft set - 288 degree intake and 280 degree exhaust. These camshafts are for use in professionally-built E46 M3 race engines. Schrick has developed these ultra-aggressive S54 race cams with 14mm of valve lift. Because of the aggressive profile and specs of this cam, Schrick only recommends them be used with special custom pistons with deep valve reliefs. We strongly recommend these be professionally installed by an experienced engine builder to check clearances and fitment.

Schrick also requires valvetrain hardware to go along with these cams:
Schrick valve springs
Schrick rocker arms
Schrick upper (titanium) and lower (steel) retainers
