We put a lot of thought into our new Summit® Race seats--and it shows. For example, we gave them three separate belt openings instead of one, so you can use "H" or "Y" style safety harnesses. We also added two recessed locations, so you can anchor them to a roll bar. Other features include a lower "stance" for more head clearance, cone and rib back supports for added impact protection, and a ribbed mounting base for added strength. We also added more surface texture and cover beadlocks to keep the seat covers in place.
