BC Racing Fiesta/Fiesta ST Coilovers - ER Series/ER Type Top-Mount (2011-2019)

Stock suspension on the Fiesta and Fiesta ST compromises between ride comfort and handling precision, leaving enthusiasts with a setup that underperforms at both ends of the spectrum. BC Racing's E-13-ER coilovers replace that compromise with a fully adjustable platform built around the ER Series damper and ER Type top-mount, giving the driver direct control over ride height and damping character.

Full damping adjustability. The ER Series damper offers 30 levels of compression and rebound adjustment through a single knob, letting you dial in a setup for daily commuting, canyon runs, or autocross without swapping components. Each click produces a noticeable change in damping force, so finding your preferred setting is straightforward.

Ride height adjustability independent of spring preload. BC Racing's separate spring perch and lower mount design allows ride height changes without altering spring preload. Lower the car for reduced center of gravity and improved cornering response, then set spring preload independently to match your load and driving style.

ER Type top-mount included. The ER Type pillow-ball top-mount replaces the rubber OEM mount with a more direct connection between the damper and chassis. Eliminating rubber compliance from the top-mount sharpens steering feedback and reduces flex-induced vagueness in hard cornering.

Threaded sleeve construction throughout. Height adjustment runs along the full length of the threaded body, giving a wide range of lowering options without sacrificing suspension travel. All adjustment collars are indexed and lock securely against the sleeve to prevent creep over rough surfaces.
