GSC Valve Spring & Camshaft Upgrade Kit – BMW S58

GSC S58 Camshaft & Valve Train Upgrades

The GSC S58 camshaft lineup is built for serious performance — delivering stronger power, improved efficiency, and rock-solid reliability at high RPM. Whether you’re building a responsive street car, a high-boost setup, or a full race engine, GSC cams unlock airflow and performance the factory setup simply can’t match.

For best results, GSC recommends pairing these cams with their beehive valve springs and lightweight titanium retainers. For full-cylinder-head builds, upgraded intake and exhaust valves, guides, and seals ensure maximum durability under extreme conditions.
