Description
The GSC Power-Division BMW/Toyota B58 284/288 S2 Billet Camshaft Set is an extreme-performance valvetrain upgrade engineered for high-horsepower BMW B58B30C Double VANOS and Valvetronic engine applications. Designed for the 2018–2024 Toyota GR Supra MKV and BMW G-series B58-powered vehicles, the S2 camshaft set is optimized for aggressive power builds requiring maximum airflow, extended RPM capability, and increased top-end performance.
Developed by GSC Power-Division, the S2 billet camshafts are intended for serious street, drag, and motorsport applications targeting 600–1200 wheel horsepower setups. The cam profiles are engineered to significantly improve engine breathing and high-RPM efficiency while maintaining compatibility with the factory Double VANOS and Valvetronic systems.
Manufactured from premium forged billet construction, the GSC S2 cams deliver exceptional durability and valvetrain stability under high boost and extreme engine loads. The design supports an operating range of 3500–7500 RPM, enhancing upper RPM power production and extending usable powerband characteristics for large turbo and built-engine configurations.
The intake camshaft features an integrated trigger design to ensure proper engine management compatibility and accurate timing control.
Due to the aggressive camshaft profiles and increased valvetrain demands, upgraded valve springs are required for proper operation and reliability.
Fitment compatibility is based on OEM exhaust camshaft part number 11318631648, ensuring proper pairing with supported B58 engine variants.
