Racetech RT4100HR Racing Seat

The Racetech RT4100HR is a standard-sized fiberglass race seat designed with integrated head restraint wings to enhance safety in high-speed motorsport environments. Engineered with optimized geometry, the RT4100HR provides a lightweight, durable seat shell that offers the perfect balance of comfort and protection. Borrowing back-mounted technology from the elite Racetech 119 and 129 Series, this seat allows for back mounting to the roll cage at shoulder level, increasing safety during racing events.

With large harness guides and a removable molded base cushion, this seat is adaptable to drivers of varying heights. Breathable Spacer fabric, parallel sides, and pronounced thigh support ensure both comfort and control. For larger drivers, the RT4100WTHR model offers additional height (+60mm) and width (+40mm). For those preferring a seat without head restraints, the RT4100 and RT4100WT complete the versatile 4100 Series.
