Honda AP1/AP2 S2000 (00-09) BC Racing ER coilover kit 10/10 kg/mm
The BC Racing ER coilover kit S2000 (part number A-09-ER) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Honda S2000 AP1 and AP2, model years 2000 to 2009. The spring rate is 10 kg/mm front and 10 kg/mm rear.
The ER series is the BC Racing coilover kit with external reservoir for serious track and competition use. For the Honda S2000 AP1 and AP2, it is the kit for those who use the car mainly on the track.
You set compression and rebound independently of each other, each in 30 clicks. The monotube dampers contain a double piston and fully synthetic oil with an ultra-high viscosity index, with a digressive damping curve. The ride height is infinitely adjustable via the damper body, and the springs are 10 kg/mm front and rear.

Fitting and delivery
The ER kit is vehicle-specific for the S2000 and replaces the original dampers and springs. We recommend having it fitted by an experienced mechanic and then having the wheel alignment set again. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing is temporarily out of stock, you can still order the kit and we will let you know when it will be delivered.
The BC Racing ER coilover kit for the Honda S2000 (A-09-ER) has an external reservoir and 2-way adjustment, with 30 clicks of compression and 30 clicks of rebound.
Why choose this ER coilover kit S2000?
Anyone who drives the S2000 seriously on track wants to be able to make adjustments without one setting affecting the other. With this kit you adjust compression and rebound separately, so you can work specifically on turn-in, grip over kerbs and composure as the suspension extends. The 10/10 kg/mm springs give you a solid base for that.
