Overview

What it does

The MX-5 NB came with an electric antenna. This base conversion fitting replaces it, so you can run the HFM.Parts billet aluminium short antenna on your NB.

It’s machined from T6-6061 billet aluminium.

Will it fit my car?

  • MX-5 NB: yes. Remove the electric antenna and fit this base.
  • MX-5 NA: not needed. The short antenna fits the NA’s factory manual antenna hardware on its own.

This fitting works with the HFM.Parts short antenna only.

We have only confirmed fitment for the vehicles mentioned under compatibility. If your vehicle is not listed, then we don't know if it fits.
Yes. This base only works with the HFM.Parts short antenna, so you'll need both.
No. On an NA with the factory manual antenna, the short antenna fits on its own. It doesn't suit an NA with an electric antenna.
The short antenna suits the MX-5 NA and NB only.

Our Story

We weren't always HFM.Parts; we were Holford Motors. Our brand's identity was forged not in an office, but on the local circuits in the high-stress world of competitive drifting. Our ultimate testbed was our Nissan S14 Drift car, driven by champion Luke Fink. Pushing that car to its limits exposed a crucial truth: achieving genuine, repeatable performance meant relying on components that simply weren't available affordably on the market.

The HFM.Parts brand was born

We made the commitment to design and manufacture the uncompromising, high-quality performance parts that we, as competitive racers, demanded ourselves. Every component you see is a solution conceived, tested, and proven by us. When you choose HFM.Parts, you are investing in components engineered by racers, for racers, ensuring your vehicle delivers its maximum performance potential.

    Absolutely love the front and rear cover set. Perfect fit, no issues. Very good quality. Transformed my interior. So glad someone is producing these covers , a lot better than the Nissan Nismo covers. Buying another set for my other R32gtr.

    This was the first product that I’ve ever purchased from HFM and I am very impressed with the quality of both items. I was particularly impressed with the shifter boot as it has the locating plastic guide at the top which means it looks neat and similar to an OEM finish.

    Very easy to install and a very nice looking piece to refresh the interior.
