BC Racing DS Series Coilovers – BMW Z4 M40i (G29) B58

OVERVIEW

The BC Racing DS Series brings the same 30-way adjustable damping as the BR Series with firmer, Drift-Spec valving for harder track use. For the RWD G29 Z4 M40i it's the pick when you want a more aggressive setup than the BR while keeping full ride-height and damping adjustment.

• Full-length adjustable ride height with a shorter shock body for lower, more aggressive stances
• Mono-tube design with a fixed lower spring seat
• High-tensile SAE 9254 springs; Swift spring upgrade available
• Front camber plates included where the application allows
• Fully rebuildable and serviceable; 1-year warranty
