A Planted Technology seat bracket for the Mazda MX-5 on the NB chassis, 1998 to 2005. Part number SB109.
The standard height version. The low version is SB255, and on an NB that choice matters.
Which height you want
An NB is small inside and the standard position is high relative to the screen. Anyone tall, anyone in a helmet, and anyone running a roll bar will want the low bracket. This standard height suits a shorter driver or a road car where you want to keep the eye line you are used to.
Tell us your height and how the car is used and we will recommend one honestly.
What the NB changed
The pop up headlights went, the shell got stiffer, and the later cars gained a six speed gearbox and a limited slip differential on some specifications. It is the more usable of the two early MX-5s and still light.
Practical
NBs rust round the sills and floors in the same places NAs do. Get the carpet up and look properly before you spend.
Ask us about the lighter shells, because the car is light.
Have you written anything useful for my car?
Yes: Corbeau PSR Seats In A Mazda MX-5 Mk1: The One Bracket That Takes Them, and Top 5 Bucket Seats For Your Mazda MX-5 Mk4 (ND), And One Kit That Fits Them All. Those are written around the same car, from real fittings and customer questions, so they are worth a look before you decide.
Will this fit my car?
This frame is made for the Mazda MX-5 Miata. Chassis code and years matter more than the badge, as floor pans change between generations, so if your car sits near a changeover year, send us the registration and we will confirm before you order.
Which seats does it take?
Check the bolt pattern in the specification against your seat. The Compatible seats tab above lists what bolts straight on. If your seat is not listed, tell us what you run and we will confirm the fit.
Do I keep fore-and-aft adjustment?
Only with a sliding runner between the frame and the seat, which is a separate part on Planted frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Is this for the driver or passenger side?
Both sides are available on this listing, pick driver or passenger side at the point of order (sides listed are for right-hand-drive cars). Left-hand-drive car? Ask us, as the sides swap over and availability varies by model.
