Paco Motorsports seat bolsters for NA/NB Miatas
Add some support to your old seats!

Made in the USA

Exclusive to Flyin' Miata

Availability: In stock



As Miatas age, the foam in their seats softens up. This can mean a drop in lateral support on the base as the outer bolster gets all floppy and pounded flat. Paco Motorsports has come through with a clever solution.

These bolster supports install in a few minutes using existing bolt holes. It adds some steel support to the bolster, giving it the strength it needs to hold you in place.

Sold in pairs (one for each seat), fits all factory NA and NB seats.

A sad letdown
I really wanted to like these. They're a great, 5-star idea, but... There aren't any installation instructions. It's pretty clear what goes where, but some guidance would've been nice. The biggest problem is that these bolsters are cut from such thick stock that they don't allow the two side bolts on the seatbelt latch (NB2) to properly thread into the seat pan once the inner seat track is bolted to the pan. I tried threading those two latch bolts first, but then I couldn't get the two bolts to reach the pan through the holes in the bolster and seat track. Felt it was better to have all four bolts installed as Mazda designed, so I only installed the bolster on the outside of the seat. I also hoped the bolster would have some flex to it, but it has no give at all. That'll help on right-hand turns, but my left hamstring will be the final judge of this project.

brilliant ..... absolutely brilliant ..... being reassured by the first reviewer that they would fit on both sides of oneseat, I did just that - my Australian arse/ass [bum/butt] fits nice and firm - add a CG-Lock and no knees needed around corners/bends

Worth the money!
Just took my first drive after installing the seat bolsters. BTW, they CAN be installed on both sides of a seat! I'm 6', 170lbs. These are NOT for big people. That said, they fit me just fine & provide a Good upgrade to the OEM bolsters.
