The stocks seats have seen better days. They are dried and cracked and their only "grip" seems to be tiny fibers from the "horsehair" stuffing poking through your clothing. Even when reupholstered they don't do a great job of holding you in place during "spirited driving".
With this not being far from a show car restoration I decided to swap the seats with something completely different. Ebay has basic "racing seats" that would work but they tend to be cheaply made and don't last. I opted for something I already knew I liked that was available locally: Mazda Miata seats.
Having campaigned a '94 Miata in autocross on the east coast I knew the fit and finish was great. Its a restomod build so purists need not apply. I picked up a set at the local junkyard, took them completely apart, refurbished and reupholstered them. Now I'm just waiting on fabbing seatrail mounts.
