Kelford BMW S58 Camshafts 298/292 | Stage 3 | 358-C

BMW S58 Stage 3 camshafts — 358-C

298°/292° duration and 10.40 mm/10.80 mm valve lift. Kelford describes this drag-racing profile for professionally built S58 engines targeting more than 1400 hp, high boost and 76 mm or larger turbos, using an ethanol blend or methanol.

Supporting parts and checks

A valve spring upgrade is required; Kelford recommends KVS58-BT. Check the new cam lobe against intake intermediate rockers. OEM pressed-steel rockers may need trimming or deburring to clear the larger lobe. Professional measurement and assembly are essential.

Fitment and installation

For BMW S58 engines. Confirm the engine build, valve springs and clearances with the installer before ordering. BBT can help plan the camshaft and supporting valvetrain package.
