Racetech RT4100 Racing Seat - Standard Size (RT4100-110)
The Racetech RT4100 Racing Seat is a lightweight fiberglass competition seat engineered for drivers who demand comfort, safety, and performance without sacrificing cockpit space. Designed as a standard-sized racing seat, the RT4100 strikes the ideal balance between shoulder support and overall fitment, making it suitable for a wide range of vehicles and driver builds. Whether you're building a dedicated track car, club racing machine, or street/strip drag car, the RT4100 delivers the support and confidence needed for serious motorsport use.
Drawing inspiration from Racetech's flagship 119 and 129 Series seats, the RT4100 incorporates advanced back-mount technology that allows the seat to be secured to the roll cage at shoulder level for additional support and safety. Large harness guides accommodate a variety of racing harness configurations, while the removable molded base cushion helps drivers of different heights achieve an optimal seating position. Breathable Spacer fabric, parallel side bolsters, and pronounced thigh support provide outstanding comfort during extended driving sessions, making the RT4100 an excellent choice for both competition and high-performance driving environments.
