BC Racing 15 BMW 4 Series M4 Cabrio (3-Bolt Top Mounts) Coilovers fits_2009-`Infiniti`FX35 Each ZR Series Coilover System

Each ZR Series Coilover System is track tested and developed specifically for racers looking for more damping adjustability than the ER or HM Series can provide

No more of the black hose breaking down in the clutch fluid and turning your fluid black

BC Racing's new proprietary digressive piston design offers increased damping force at low piston velocities while maintaining a linear damper feel at higher piston velocities

This increases the capacity of the unit which increases the volume of oil which in turn reduces the peak temperature and significantly improves damper performance

The external reservoirs allow for a higher oil capacity with the added benefit of increased thermal dissipation
