Has anyone installed Miata seats in a MGB? I am looking for a good upholstery kit for the seats. Any good reviews for a good fit. I have looked at Mr. Mikes and katz skins. I am looking for other choices for well made covers.

Thanks , Ron

IMHO Miata seats are (a) not more supportive than MGB stock seats, (b) are harder and less comfortable, and (c) sit you a little higher in the car than before which is not a problem if you are short or medium heights, but can be annoying if you are tall.

If I were to do it over again, I'd rebuild my MGB seats instead of installing the Miata ones.

I elected to go with Fiero seats with kits from Mr. Mikes.

One of the things I find interesting is MGB guys want Miata seats because they are better. And the Miata guys want to get rid of their seats for better seats. Perhaps it's a matter of perspective. I had a Miata and didn't care for the seats, too stiff.

The seats in my GT had that sinking feeling. To solve the problem I installed both the diaphragm and straps under the seat cushions. Much better.

Do a search of this forum.

A great many owners have chosen this seat install.
I am sure you can find the pros & cons you are after

To make mine more weather resistant, I plan on neoprene seat covers. Several brands are available. I had them in my Mini and they worked very well. If you search enough places, I know I have seen leather re-upholstery kits.

Not the OP's question, but I am just under 6 foot and find mine very comfortable. The higher headrest is a big safety improvement. I think the Fiero seats look out of place in the B. Side bolsters are a big improvement for spirited driving. I don;t think they are actually more than maybe half an inch higher that good condition stock. of course, most stock seats sag quite a bit. It may depend on how you mounted them. I used generic rails from Summit.

I found two very good 92 Miata seats and reversed them for install - passenger on drivers side and visa versa.
I did the install using a homemade steel plate, drilling holes to line up with the Mgb seat holes and holes to line up with the Miata sliders. MGB bolts went into the captive nuts and Miata bolts came up thru the bottom of the plate and were secured with nuts and washers.

I am VERY satisfied with the results. I really liked the Miata seats when I had a Miata and I am very satisfied with them in my B. When doing spirited driving I am not holding the steering wheel for dear life and I like the fact that I am not feeling like I am sitting on my living room couch. The Miata seats are not race seats but I think they are a great improvement over stock seats.

I put Miata seats in my GT. They are quite a bit firmer and definitely safer than my old MG seats. My install feels a little lower than the original seats but I bolted them directly to the floor. Haven't re-upholstered them yet but like the look of Mr Mikes, will likely go that way when I redo the interior. A restoration & historical journal MG Resource Directory

After recovering the original seats in my '67, my wife insisted that I have headrests (even a minor hit from behind can really cause neck problems).
I found some cloth miata seats on craigslist for $70. After a few years, the cloth started to come apart and I got these covers from amazon:

They were a little more work to recover than the original seats, but I think it came out OK. I've been using them for several years of daily driving.
There are speakers in the headrests. They help more than I thought they would on overcoming wind noise vs. music.
They do sit you a bit higher. When I am sufficiently motivated, I may try cutting the seat base foam a bit.
(The seat bottom pan is already hitting the carpet, so I can't lower it any more.)

I have 1st Gen Miata seats in my '71 B. The upholstery is the original charcoal grey fabric. When I went looking for replacement cloth upholstery kits a couple years ago, I found exactly none in the aftermarket, although I could find leather and neoprene. Not interested in those options, I had an upholstery shop repair the rip in the driver's side left upper bolster by sewing in a nice looking asymmetric patch. Good luck with your search.

I like the seats better than the stock MGB seats - the bolsters make it easier to exploit the car's handling capabilities.

I was rear-ended while in an old VW, and have back problems decades later. I simply do not trust seats from the 60's & 70's.
I put Miata seats in my '71 GT, and they are fine. I have faith that I won't snap my neck if I get rear-ended - a faith I didn't have with stock MG seats.

I also found that swapping them left/right makes them fit better.

Another vote for 1st generation Miata seats. I have them in my BV8. Speakers in the headrests. Good support and comfortable for long distances.

Yep, done the 1st Gen Miata (they are MX5's here) seats a month or so ago. Very much an improvement.

IMO the B seats are glorified deck chairs, and very expensive to refurbish properly compared to buying good used Mazda seats.

As an alternative, Mirror Trim here in the UK (ships worldwide) do a 'Next Generation' seat which is built on the standard seat frame.

It has much deeper and more sculpted foams so that it has great lumbar support, much better side support and support under the calves of you leg.

After trying these out I've just ordered pair of these, they are more comfortable than the seats in my new Mercedes.

Worth a look.

So Chaz, I know I could send Mirror Trim an email, but just to clarify that's a complete seat including frame and not just a cover over your own seats?

Fidanza FW. Basil's followers and pushrods. TR7clutch. TT exhaust. ARP everywhere. 123 ign. Needham 4synchro c/r box.. Stock rebuilt/replaced suspension. Superpro bushes. New brakes all round including all pipes in SS flex. Interior redone. CAMS approved roll bar and side bars. Lots more. Hybrid of o/e and show/fast road car. Not for sale - it's my toy!

GT: UK car built/sold December '78. Stripped back to bare shell (with extensive bodywork to come). Powered by 'worked' Rover 5 litre V8 (ex TVR Chimera) with efi. T5 box. FC IFS. CCE rear attached to Salisbury axle with Quaife. And a whole lot more to yet to come. Stealth is the word.
