5X Racing Spec Miata Coilover Kit

Spec Miata Coilovers


These parts comprise the Spec Miata coilover system used in SCCA and NASA racing. The parts are all 100% rule book legal and are in accordance with the specified shocks, springs, and genuine Fat Cat shock mount system outline within the rules. The coilover sleeves are our own, but are legal (see this article: SM Rules Case Study 1: Coil-Over Kits). The kit is available in individual loose piece form (assembled yourself) to save costs, or in pre-assembled bolt-in ready form for an additional $100 by selecting the option using the drop-down menu.

Availability: Delay possible depending on inventory.

    If you're not sure on how to assemble this kit - or just want to make it easier on yourself - you can select the option to have us pre-assemble the coilover kit for you. Here is what you get and what we do for our special $100 pre-assembly option:

  • We bead blast the surface of the shock hat in which the Fat Cat spring isolator gets glued to. We also prep the surface of the isolator as it is very slick and can become separated from the shock hat if not made to adhere better. This ensures the isolator stays in position and does not separate over time
  • We then use a slight bead of silicone to seat the coilover sleeves to eliminate having them turn when you adjust your spring heights after they're installed
  • We properly install the Fat Cat Bump Stop kit, which can be tricky if not good with directions
  • We will set the spring adjustments to match the ride height of our current setup on our race cars. This should be used as a guideline and we recommend you scale and balance the car regardless of our settings. We tend to like our cars loose, so our settings will reflect this style of driving. Our base settings are meant to be a starting point
  • Shocks will be labeled to their specific corner, and shipped as a "bolt in" installation
