GSC's S58 camshaft lineup is the benchmark for power, efficiency, and high-RPM stability in BMW's latest M engines. Whether you're building a responsive street car, a high-boost drag setup, or a full competition engine, GSC cams unlock airflow the factory profiles simply can't deliver.
Pairing these cams with GSC beehive valve springs and titanium retainers is strongly recommended. For full cylinder head builds, we also suggest GSC's upgraded intake/exhaust valves, valve guides, and stem seals for maximum durability and performance.
Stage 1 - 500-900 WHP
Perfect for responsive street/track builds seeking faster throttle response and strong mid-range torque while maintaining excellent drivability.
Benefits:
- Ideal operating range: 3500-7500 RPM
- Quick throttle response + noticeable mid-range gains
- Integrated intake cam trigger
- Forged billet construction
- Upgraded valve springs required
Specs (7093S1):
Stage 2 - 800-1400 WHP
A more aggressive profile aimed at high-boost builds where top-end flow becomes critical. Ideal for upgraded turbo systems and built engines.
Benefits:
- Ideal operating range: 4500-8500 RPM
- Faster response + stronger mid-range than stock
- Integrated intake cam trigger
- Forged billet construction
- Upgraded valve springs required
Specs (7093S2):
Stage 3 - 1200-1800 WHP
Engineered for competition-level airflow at extremely high engine speeds. Stage 3 shines in big-turbo, high-boost S58 builds that live high in the rev range.
Benefits:
- Ideal operating range: 5200-9200 RPM
- Massive airflow for top-end horsepower
- Integrated intake cam trigger
- Forged billet construction
- Upgraded valve springs required

Important Notes
- Upgraded valve springs are required for ALL stages.
- A custom ECU tune is mandatory.
Because these cams dramatically increase airflow, the engine will run lean on the factory calibration. A proper tune ensures performance, safety, and drivability.
