Racetech RT4100HR Racing Seat

The Racetech RT4100HR is a premium FIA-approved fiberglass racing seat designed for drivers who demand exceptional safety, comfort, and support. Featuring integrated head restraint wings, the RT4100HR offers enhanced lateral head protection while maintaining a lightweight shell with optimized driver ergonomics.

Drawing from Racetech's proven 119 and 129 Series, the RT4100HR incorporates back-mount technology, allowing the seat to be securely attached to the roll cage at shoulder height for increased rigidity and safety.

Large harness openings accommodate a wide range of racing harnesses, while the removable molded base cushion allows drivers of varying heights to achieve a comfortable driving position. Breathable Spacer fabric, parallel seat sides, and pronounced thigh support help reduce fatigue during long days at the track.
