-800x800.jpg "RT4100 Racing Seat: RTB1009M side mount brackets")
The RT4100 is a standard-sized fibreglass race seat. We have focused on achieving a lightweight seat shell with optimised 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 roll cage at shoulder level. Large harness guides and a removable moulded 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, the RT4100T uses the WT shell, with additional high-density foam from the sides up to the shoulders. For the larger driver, the RT4100WT is 60mm taller and 40mm wider than the standard seat.
The 4100 Series seats use either Racetech RTB2009S (steel) or RTB1009M (aluminium) side mounting brackets.
