5X Racing Rear Coilover Spring Adapter for 2006-2015 Mazda MX-5 NC

We were able to get our hands on a few trick parts used in the old MX-5 Cup cars and recreate them. This was one of those parts. This adapter is critical if you're trying to build a coilover setup for your 2006-2015 Mazda MX-5 NC chassis because the rear shock mounts on the NC are these awkward aluminum "cones" that don't work too well with allowing a 2.5" coilover spring to interface with them. These adapters are made out of delrin and are exact replicas of the adapters that were used in the MX-5 Cup coilovers during the reign of the NC chassis, so we know they'll work properly as they were used on professional racecars for many years.
