GSC Power-Division billet cams for the BMW / Toyota B58B30C Double Vanos, Valvetronic (variable lift) power plant of 2018+ BMW G-Body Vehicles and the Toyota MKV Supra 3.0.
GSC Power-Division got their start in the Japanese compact market, offering high-quality performance cams and valvetrain components that combined quality and weight savings for turbo sport compact engines.
Using high quality materials and modern manufacturing techniques, GSC has expanded their catalog to include the BMW and Toyota B58 engine, applying the same techniques they learned from designing and manufacturing turbo cams for the Japanese compact market to the turbo BMW motor.
Constructed from forged billet, these cams feature an intake trigger and require the use of uprated springs.
