BC Racing ER Series Coilovers For Mazda MX-5 NA NB
BC Racing’s premium flagship coilovers are the external reservoir ER Series with separate compression and rebound damping adjustment. The ER Series coilovers bring with them the high quality and unique features seen on the BR but have the additional benefit of external reservoirs and the ability to allow the end user to individually adjust and set compression and rebound damping rates.
The external reservoir ER Series coilovers allow BC Racing to increase the oil capacity of the damper unit. The additional oil capacity reduces peak oil temperatures which decreases variations in damping rates due to oil viscosity changes. The reduction in damping rate variations improves handling and ultimate on road and track performance.
The pillowball upper mount is made from aluminium alloy, anodised and then bead blasted to give a high quality, durable finish. Made in Japan, the pillowball eliminates any flex or play associated with the standard rubber mounts so improving response and handling.
