BC Racing DS Series Coilovers – BMW 540i (G30, RWD) B58

OVERVIEW

The BC Racing DS Series is a firmer street-and-track focused coilover built on a mono-tube damper with a proprietary digressive piston that delivers more damping force at low shock speeds for sharper body control. For the RWD G30 540i it offers 30-way adjustable damping and full-length adjustable ride height in a more performance-oriented package than the BR Series.

SPECS

• 30-way adjustable damping (compression and rebound together)
• Proprietary digressive piston for increased low-speed damping force and sharper response

• High-tensile SAE 9254 springs; Swift spring upgrade available
• Front camber plates included where the application allows
