Racetech RT4200HR Racing Seat

The Racetech RT4200HR sits at the sharp end of their fiberglass range, combining deep head restraints, reshaped thigh support and a more upright driving position for modern GT and touring cars. If you are building a dedicated track or race car and want serious containment without jumping all the way to a carbon shell, this is the sweet spot.

Why we like the RT4200HR

• FIA 8855-1999 approved composite head restraint seat for high speed impact protection
• Taller, reshaped rib and shoulder bolsters that work well in high grip aero cars
• Improved thigh support to keep your lower body planted under big brake zones
• Well placed harness slots that align cleanly with modern 6 and 7 point harness layouts
• Multiple cushion options so you can tune seat height and lumbar support to taste
• Compatible with Racetech side brackets and back mount hardware for a rigid, confidence inspiring install

This listing covers the RT4200HR standard shell. It suits medium sized drivers looking for a containment style seat for road race, time attack, hill climb and similar applications.

Installation notes

Like other Racetech head restraint seats, the RT4200HR is designed to be side mounted and back mounted into a proper roll cage structure. Take the time to position steering, pedals and harness angles around the seat, not the other way around, and always have the mounts checked by an experienced fabricator before track use.
