I would either find another OEM set or recover your before I’d go race seats unless you’re going to be doing a LOT of track time.
And even then, I don’t know if I’d go race unless they require a FIA seat.
I’m doing custom seats up for the Firebird; similar to Lafengas’s but more extreme with deeper seating, and more boulstering both leg, side, and shoulder; with holes for 5-pts integrated in. Seeing I can do the upolstery work too, it shouldn’t be that bad of a project.
