A Planted Technology seat bracket for the Mazda MX-5 on the NA chassis, 1989 to 1997. Part number SB101.
This is the standard height version. There is also a low version under SB245, and on an NA that choice matters a great deal.
Which height you want
An NA is small inside and the standard seating position is high relative to the screen. If you are tall, or you wear a helmet, or the car has a roll bar, the low bracket is almost certainly what you need.
The 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 rather than let you guess.
Weight is the point of the car
An NA is around 950kg and that is the entire basis of how it drives. A heavy steel framed shell gives back a real slice of it, so ask us about the lighter GRP and composite options.
Practical
NAs rust round the sills and floors, and thirty five year old ones deserve a proper look with the carpet up before you spend.
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.
