Stage 2 racing camshafts for professionally built BMW S58 engines, capable of delivering 800hp to 1,400hp with 66-75mm turbo sizing and aftermarket intake plenums.

• These camshafts enable full use of Valvetronic and Dual VANOS, while also allowing you to lock Valvetronic when using an aftermarket throttle body. Please check valve-to-piston clearances on full travel of VANOS and Valvetronic.
• Valve spring upgrade is required — Kelford Cams recommend valve spring kit KVS58-BT.
• Ensure clearance of the new racing cam lobe with the intake intermediate rockers, and trim or deburr OEM pressed steel rockers if necessary.
