03-10 BMW X3 (AWD) E83 - BC Racing DS Series Coilovers

BC Racing DS Series Coilovers are engineered for drivers who demand precision and control on track without sacrificing road compliance. Featuring a proprietary digressive piston design, the DS Series delivers enhanced low-speed damping for superior handling through corners, acceleration, and braking.

• Digressive damping curve for sharper response and improved chassis control
• 30 levels of simultaneous compression and rebound adjustment
• Ride height adjustment independent of spring preload
• Camber-adjustable top mounts (where applicable)
• Pillowball top mounts for direct steering feedback
• Custom spring rates available on request
• Satin chrome-finished 53mm damper body for increased oil capacity
• 46mm piston for consistent damping performance
• Dust boots to protect damper seals and extend service life
• Fully rebuildable with readily available spare parts
• 12-month manufacturer’s warranty

The digressive valving allows higher low-speed damping to control body roll and pitch, while reducing high-speed damping to absorb kerbs and bumps without upsetting vehicle balance. Ideal for track days, spirited driving, and technical road courses.
