FAQs
Will your gear knobs fit my Mazda MX-5 / Miata?
Yes! Our MX-5 gear knobs are compatible with all four generations: NA, NB, NC and ND.
We offer two options: our OEM Replica shape or a gear knob paired with our MX-5 Collar. Both options fit all generations, so it comes down to your preferred style.
What thread size does the MX-5 / Miata use?
The Mazda MX-5 / Miata uses an M10 × 1.25 thread.
When customising your gear knob, select M10 × 1.25 under the Adaptor option. The adaptor is included with your gear knob.
Do I need the MX-5 Collar?
The collar is recommended when fitting one of our standard gear knob shapes, particularly the Full Ball.
It covers the exposed space between the bottom of the gear knob and the top of the gear lever boot, giving everything a neat, finished appearance.
Our OEM Replica shape does not require the additional collar.
What's the difference between the OEM Replica and Full Ball with Collar?
Our OEM Replica is inspired by the original MX-5 gear knob, offering a more traditional appearance.
The Full Ball is a rounded design that pairs with our MX-5 Collar to create a different look.
Both options are compatible with all MX-5 generations, so the choice is entirely yours.
Can I fit a gear knob without the MX-5 Collar?
Yes! Our gear knobs can be fitted directly onto the MX-5 gear lever using the correct adaptor.
However, there will be a visible gap between the bottom of the gear knob and the top of the boot. Our MX-5 Collar is designed to cover this space.
How much do the MX-5 gear knobs weigh?
Our OEM Replica shape weighs approximately 160g.
Our Full Ball gear knob and MX-5 Collar have a similar combined weight of approximately 155g, depending on the materials and customisation selected.
Additional weight can be added to the Full Ball gear knob if preferred.
Can I customise the wood, colours and engraving?
Absolutely! Our gear knobs can be customised with your choice of wood, layering style, colours and finish.
You can also add an engraved gear pattern, logo or initials to suit your car.
Do I need any tools to install my new gear knob?
No tools are required. Simply unscrew your original gear knob, fit the collar if you're using one, and screw your new gear knob into place by hand.
You can follow our photo guide and installation video above.
If you are fitting our OEM Replica Shape with engraving, you will need medium strength Locktite (243 blue) to hold the gear knob in the correct orientation when fitted.
