Over the past 25 years, we’ve perfected both the vintage Sport Seat and the customization process. Each GT Seat Shell is constructed from durable fiberglass with steel reinforcement bars laminated into the base, delivering a rigid yet lightweight structure. A threaded steel base ensures secure mounting through steel, not just fiberglass. We also offer a range of sliding frames allows for easy installation across a variety of vehicles and applications.
Seat frames and hardware are sold separately. This option is ideal if you plan to complete your own upholstery. For upholstery options, contact us at info@fibersteel.com.
