Designed specifically for performance driving, the FR-Spec coilovers feature an increased spring rate and increased damping coefficient in the shocks over the F-Spec to provide ultimate handling and vehicle control under aggressive driving conditions.
Difference between F-Spec and FR-Spec:
More aggressive shock valve
Fluid viscosity
5W for F-Spec
20W for FR-Spec
Shim stack
Stiffer spring rates
Pillowball aluminum front top-hats
32-way adjustable monotube shock with internal piston and damping stack tuned for aggressive driving.
High Temperature / higher stability shock fluid to better suit circuit driving.
Adjustable aluminum upper pillow ball mounts to reduce suspension deflection under aggressive driving conditions while allowing for fine alignment adjustments
