i'm sorry i screwed up the hyperlink. here is the link to the correct sidemount/base como Planted Low Profile Seatbase Adapter - Mazda Miata (NB) 1998-05 - Driver

if your looking to get as low as you can then i would advise on not getting the sliders. if you don't mind the height then you can run sliders.

How do adjust your position in the car with no sliders? You bolt it in to your needed position and then if it ever needs to move you have to completely unbolt it and bolt it down again?

I really like the looks of those medium size Sparco Ergos. Will those fit in an NB easily?

yep. it's a bolt in adjustment. move the seat around to what ever hole you want to use and lock it in place.

A excellent video of why Halo restraints are so important.

Looks so much more violent in slow mo.

We just installed the Kirkey 71 series Full Containment in the new Enduro car and it is by far the most comfortable thing to spend 2 hours wresting a 250hp car around the track in! The craftsmanship, weight, and fitment are all amazing. We stepped up to it from the Ultrashield Rallysport. The taller and extended leg bracing feels fantastic, plus you can adjust the height of the seat back/shoulders/halo to fit almost anyone. Everyone who has raced the car this season immediately compliments it. Highly recommended.

Kirkey Rear Mount - 71 Series Seats



you'll love it. You braced it with something like this right?

I looked at those, a great simple solution but I went with an adjustable tube design (I/O Port) to accommodate our cage installation.
