Koni/Ground Control/Eibach/FatCat Coilover Shock Setup for NB Miata
I purchased these parts new in 2014, and installed them to my Miata with the original top mounts, but assembled with all new Mazda OEM bushings and spacers ordered from Mazda Motorsports. Approximately 22k miles on these parts.
Will fit 1999-2005 Miatas. Buyer is responsible for independently confirming compatibility with any other application.
I’ve run these over the years with various versions of the “latest” hot 200TW street tires in 225/45/15, also switching between 8 and 9 inch wheels. Comfortable enough to daily with a 205/50/15 all-season, but quick and controlled on 225s with the damping turned up. Good enough on my car to put me 3rd on raw time at the end of the morning sessions of the April event. Includes Koni adjuster tool and Ground Control spanner and Allen wrench for lower perch. Full parts inventory of this setup listed below for estimate of cost to create this.
