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 F-Spec Street Coilovers. These are ideal for those of you looking to achieve that aggressive lowered look while improving the handling and steering response of your vehicle. These have been engineered using the right spring rates so that you can have an efficient suspension package without compromising the overall ride quality. 



  • Increased spring rates and shock valving over stock suspension with emphasis on street performance while not jeopardizing ride quality and comfort
  • 32-way adjustable monotube shocks allow for stock-like ride quality on the soft setting while providing enough adjustment to stiffen up the ride for the weekend track days or canyon drives
  • The adjustment allows customers to fine-tune ride quality from soft to stiff in order to meet their road surface and driving environmental needs
  • Rubber isolated top-hats feature a high durometer rubber mount to reduce deflection while isolating unwanted minor vibrations and road imperfections
  • Includes height adjustment tools
  • Includes damping adjustment tools


  • 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

    Feels 100 times better! 3 months ago
    5out of 5stars

    I was previously on H&R springs with the stock struts and the ride quality was horrible. It was super bouncy and stiff on every bump. I felt bad whenever I would have passengers. After installing these, it was a HUGE difference in quality. I was able to adjust the height where I wanted while keeping the ride quality perfect. When there’s passengers I can set the dampening to a softer setting and you could barely feel any bumps in the road. Overall I’m really happy with these coilovers and would recommend them to anyone who uses their car as a daily and light track use.

    Factionfab F-Spec Coilover 3 months ago
    5out of 5stars

    Love the coilover, quality on the ride is smooth not super stiff with the setting around 20. Rear sleeve max out and I got a one finger gap rear, the front slight below a finger. The only thing for me I didnt like was trying to loosen the lock ring on the sleeve that didnt want to come loose once you tighten them. But in a way, that is good since you know it would not come loose while driving. I would definitely recommend these coilover.

    These coilovers are the best bang for your buck. They ride almost similar to stock, but can be adjusted to a desired stiffness with the 32 way dampening. No rattling, clunking, or squeaking with these coils which keeps the daily commute nice and quiet. I highly recommend.
