Kelford Cams BMW S58 Stage 3 Performance Cams - 358-C

Kelford Cams recommends using Stage 3 drag racing cams for S58 engines that are professionally built and capable of making over 1400hp. If you plan on using high boost and 76mm+ turbo sizing, then you should be using either ethanol blend or methanol fuel.

• It’s important to upgrade your valve springs, KVS58-BT  is the recommended option.
• Additionally, please double-check clearance for the new racing cam lobe with your intake intermediate rockers.
• If you’re using OEM pressed steel rockers, be sure to deburr them to avoid any issues with fouling on the larger cam lobe.
