      Common questions

      Will this kit fit my Mazda MX5 NA/NB body styles?

      Yes — this kit fits all Mazda MX5 NA/NB body styles.

      If you have a non-standard chassis or factory suspension upgrade, contact us before ordering and we’ll confirm fitment.

      Can I adjust ride height after installation?

      Yes. All BC Racing coilovers use full-thread body construction for continuous height adjustment without affecting damper travel.

      We recommend a wheel alignment after any significant ride-height change.

      How do I adjust the damping?

      Damping is adjusted via the top-mounted dial — turn clockwise for firmer, counter-clockwise for softer. Always start with all four corners at the same setting and adjust in equal increments.
