5X Racing Spec Miata 2.5" Coilover Spring Isolator

Spec Miata Spring Isolator

21034982 - FCM-ISO-SM-95A
THE ONLY LEGAL SPRING ISOLATOR FOR SPEC MIATA! There are imitation isolators being sold by another company without full disclosure that they are NOT the spec part, please be aware that using this part would be found illegal in a post-race teardown. Our isolators are stamped with an "FCM", marking them as the spec part in the rules.
  • Priced EACH
  • Works with Fat Cat Motorsports Shock Mount kits, Spec Miata Penske coilover, and any 2.5" race spring mounting into a 99-05 Miata OEM shock hat
  • Can be used in other applications besides Spec Miata where a stiffer 95A urethane is desired. For street and sport applications, we recommend our 85A "red" isolators which offer a softer barrier between the spring and mount

    Description

    Our USA made custom 2.5" urethane coilover spring isolators are used in our coilover shock mount/bump stop kits and are designed to work with 1999-2005 NB Miata Shock Hats. They will NOT work with 1990-1997 NA Miata shock hats! They might also work with other shock hats, but we haven't tested them on anything besides the 1999-2005 Miata shock hats. The purpose of these is to center the coilover spring within the shock hat.
