Ratings & Reviews
I am 6-4 and my daughter is 5-4. We share the same car for endurance racing. Obviously we can’t share the same seat. We made quick change seats which we change out at pit stops. This bracket helps make it really easy. I just changed the one bolt to a quick release pin. Therefore it gets 5 stars.
Highly recommended I/O Port Seat Back Brace. Makes seat mounting very easy.
Highly recommended I/O Port Seat Back Brace. Makes seat mounting very easy. Put in my Howe chassis car with Kirkey seat.
Well made and secure, but not an easy install for a Miata.
Not an easy install, as most Kirkey seats do not have a flat back matching the brace bracket. Tight fit in a Miata. Securely reinforces the seat back, and is highly adjustable.
