Spring Rate Front: 12Kg/mm
Spring Rate Rear: 10Kg/mm
Here, you are looking at the Faction Fab FR Spec Track Coilovers. These coilovers have been engineered with aggressive spring rates along with increased damping coefficient in the shocks to deliver the feedback and support needed under high-performance driving conditions.
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
5W for F-Spec
20W for FR-Spec
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.
Japanese steel tube construction using SAE1010 STKM13c
Monotube shock design with high-performance mono-tube shock construction allowing for better rider control, fluid life, and thermal fluid stability
Synthetic high-performance oil
Independent ride-height adjustability separate from spring pre-load allowing the customer to set the ride height without having to worry about shock travel
Top hats included allowing this suspension system to be a direct replacement for your factory suspension setup
Forged 6061 anodized adjustable collars and spring seats for easy adjustment and prolonged cycle life
Robotic welded and electroplated lower shock mounts for consistent fit and finish
Dust boots and bump stops for shock protection and longevity
Individually sold components allowing for replacement or upgrade of components as desired or needed
Plastic lower spring seat isolator to aid ride height adjustment and reduce unwanted audible noise
