The RT4100HR is a standard-sized fiberglass race seat equipped with head restraint wings for enhanced safety. Racetech focused on achieving a lightweight seat shell with optimized geometry, straddling the 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. Its patented back-mounting technology has trickled down from the more expensive 119 and 129 Series seats, giving you the option of fixing the seat to the roll cage 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. $1,200.00
