I searched and didn't find any previous threads. I also have looked as the SCCA rule book. I'd like your take on the rules around seats. How old can they be. Do they all need seat back braces (although SM has a built-in one with the rear firewall).
SCCA GCR - 79 Rule 9.3.41 Seats, with the addition of the following.
CLUB RACING BOARD MINUTES | Jan. 5, 2010
SUGGESTED RULES FOR NEXT YEAR
Item 1. #314 (Dick Patullo) Seat mounting To allow secure mounting of racing seats in categories where a limited number of cage attachment points are allowed, the CRB recommends the following change.
Effective upon BoD approval, in 9.3.41, add a new second paragraph as follows: Mounting structures for racing seats may attach to the floor, cage and or center tunnel. Seat mounting points forward of the main hoop, between the center line of the car and the driverís side door bar and rearward of the front edge of the seat bottom are not considered cage attachment points in classes with limitations on the number of attachments.

"Seats homologated to and mounted in accordance with FIA standard 8855-1999 or higher need not have the seat back attached to the roll structure."
If it's an FIA seat and the homologation hasn't expired, it doesn't require a back brace. Otherwise it does. The rear firewall does not count. Even if your seat is against the firewall, it doesn't provide lateral support and the firewall is not part of the roll structure.

I'm brand new to Spec Miata and I do have a car, but no seat yet. Must you have an FIA seat to be eligible to race SCCA or NASA? The Corbeau FX1 Pro looks nice at a great price, but is not FIA. On the flip side, the Sparco Sprint5 looks less comfortable, but is FIA. What to do...
