Product Details

BC Racing ER Series Coilovers for the 2011-2019 BMW 1 Series Hatchback (F20) put race-grade adjustability in reach of the track-day driver. A linear twin-piston mono-tube damper adjusts rebound and compression separately at every corner, with compression on an external reservoir, and ride height is set independently of spring preload.

BC Racing tests each application and chooses spring rates and damper valving to balance comfort and performance. Swift Springs, custom spring rates, and custom valving are available at checkout, and BC will valve the dampers to match. Every kit is fully rebuildable with replacement parts available from BC, and ships with a 2-year manufacturer warranty against defects.

Features

  • 30-level rebound adjustment (top of damper)
  • 30-level compression adjustment (external reservoir)
  • Mono-tube damper with linear twin-piston design
  • Ride height adjustable independent of spring preload
  • Upper mount hardware varies by chassis, camber plates, pillowball, or reused OEM mounts. See the Specifications table for what's included on your kit.
  • Swift Spring and custom spring rate upgrades available at checkout
  • Custom damper valving paired with custom spring rates on request
  • Fully rebuildable, replacement parts available from BC for the life of the shock
  • 2-year manufacturer warranty against defects
