The RT4100HR is a standard-sized fibreglass race seat equipped with head restraint wings for enhanced safety. We have focused on achieving a lightweight seat shell with optimized geometry, straddling that line between designing the seat to be wide enough in the shoulders to suit the athletic build, but narrow enough to fit in most cockpits. Our patented back-mounted technology has trickled down from the 119 and 129 Series, giving you the option of fixing the seat to the rollcage at shoulder level. Large harness guides and a removable molded base cushion allow a range of drivers of varying heights to fit. Breathable Spacer fabric, parallel sides and pronounced thigh support round off the features of this accomplished motorsport seat.

For the taller driver, we have developed the RT4100THR which makes use of the RT4100WTHR shell but has added high-density foam to the sides from the base up to the shoulders to bring the internal dimensions of the seat inline with a standard-width RT4100. This seat is 60mm taller than the standard size. For the larger driver, the RT4100WTHR is 60mm taller and 40mm wider and for those wanting a seat without head restraints, our RT4100 and RT4100WT complete the 4100 Series.

The 4100 Series seats use either Racetech RTB2009S steel or RTB1009M aluminum side mounting brackets.
