BC Racing ER Coilovers

BC Racing ER Coilovers

---

Their newest and most advanced model yet is the ER series coilover. It features large external reservoirs front and rear, separate rebound and compression adjustment and a twin piston design. The external reservoirs hold much more oil than the conventional coilover, allowing the coilover to operate for a much longer period of time before overheating. The external reservoirs also house the secondary piston, which allows for the adjustment of compression. This is the perfect coilover system for the person who wants to fine tune there setup using the separate, 30-way, rebound and compression tuning dials.

- Dual Piston design (1 in res., 1 in shock)
- Full height adjustability through shock body not spring
- 30 levels of dampening adjustment Rebound is on top of the shock, compression is on the reservoir
- Adjustable rear camber plates on certain applications only

- 1 Year warranty against manufacturer defect
- Base Shock Stroke 3.97" Front and 3.53" Rear

Optional Upgrade

Spring Upgrade? Why Swift Springs?

Make the most of your coilover system with a simple upgrade!

Swift springs of Japan noticed that most spring manufacturers use silicone chrome material. Other manufacturers use a heat tempering method that damages the strength of the spring material that inevitably requires more coils, in turn, more weight. This material also suffers from a shortened life span. With springs like this leading the industry, Swift saw massive room for improvement.

Swift's R & D team created a material, called H5S.TW. This advanced alloy is stronger then regular silicone chrome material. Swift could make the spring wire thinner, and could wind the springs with fewer coils, which greatly decreased weight while dramatically increasing available stroke.

Includes 4 main springs.

NOTE: All coilover orders from SubiSpeed (2015 WRX / WRX STI) come with a bracket for the front ABS lines.
