BC Racing’s premium flagship coilovers are the external reservoir ER Series with separate compression and rebound damping adjustment. The ER Series coilovers are designed for dual duty vehicles that require the best balance of performance and comfort. BC Racing have engineered the ER series to have the best overall compromise of spring rate, ride height range, top mount design and damping rate to suit cars that are daily driven and see occasional track or competition use.
The ER series are exceptionally capable of dealing with fast road and track work but also retains a high degree ride civility. Long journeys to and from the track are no longer tiring thanks to the work put in by BC Racing. The external reservoirs increase the oil capacity of the damper unit which helps to reduce peak oil temperatures, decreasing 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.
