Coilover BC Racing ER for Mazda RX-7 FC3S

BC Racing ER adjustable shock absorber kit for Mazda RX-7 FC3S from 1985 to 1991.

Fine tune your vehicle with absolute adjustability using the ER Type system. 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 conventional coilovers allowing the unit to operate for much longer before overheating. Additionally, the external reservoirs 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 their setup using the separate 30-way rebound and compression tuning dials.

These BC Racing ZRs are equipped with Pillowball Top Mounts to further improve steering precision and to keep the car angles unchanged. The front camber is adjustable.

Features of BC Racing ERs:

• Monotube dampers, oil + pressurized nitrogen
• Linear springs, standard rates 9 kg/mm front, 7 kg/mm rear, custom option available
• 30 clicks of compression adjustment via the external reservoirs
• 30 clicks of rebound adjustment from the top of the damper
• Adjustable spring platform (Preolad)
• Pillowball top mounts with front adjustable camber
• Bearing mounted upper spring platform
• Height adjustment via lower mount to retain full damper travel
• Dust boot to protect damper seals

Optional, it is possible to choose different spring rates. The hydraulics will be calibrated accordingly.
