Features & Product Details

RallySport Direct proudly carries a great selection of high-performance suspension components brought to you by Faction Fab. 


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
  • 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.





  • 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

    FactionFab FR-Spec Coilovers ( Part Number: 1.10174.2)
    Great coilovers for 2005 STI 1 year ago
    5out of 5stars
    I had these installed on my 2005 STI along with the Whiteline rear lateral links. 1-5/8 drop in the front and 2 inches in the rear, no alignment issues. I have not driven it much yet but they feel great! Car feels much more planted. it is a harder ride but is much smoother than the stock struts that were replaced 2 years ago. Highly recommend. I did have corner balancing done as well.

    • Q: Hieght  Trunkz2 years ago

      Does this actually raise the car at all or lower it?
      • 1 of 1 people found the following answer helpful

        A:  this can technically raise the car ever so slightly if you were to max out the lower height adjustment collars, but really it's designed to lower the car anywhere between 0 and 2 inches. Thanks!

    • Q: Confirmation  Shipping time2 years ago

      What spring rate are these? I saw a video from subiespeed and they also reviewed these coilovers. They stated the spring rates are 12k front 10k rear. On the description here its says they are 10k front 8k rear. I just need clarification on who’s right.
      • 0 of 0 people found the following answer helpful

        A:  The spring rates are specific to each model for best performance, and this set for the 05-07 STI is indeed 10k / 8k. Subispeed's video is highlighting the 2015+ WRX / STI model which has the 12k / 10k spring rate.
