Large-Race-Cam Vanos Shim Kit for BMW M50, M52, S50, and S52 Engines

Description

Reduces Vanos sweep to increase buffer for piston to valve contact. These are not required for most cam installs, but they will error-proof the install (almost) and give a higher safety margin. Use the smallest shim you can for your application – the bigger the shim, the more Vanos is limited, and the less power you make. 
Installs in OEM Vanos unit in under an hour. Large shim recommended with full race cams. 
Machined aluminum, fits all M50 based single-Vanos engines, including 323, 325, 328, M3 and Z3 6-cylinder.
