-800x800.jpg "RT4100WTHR Racing Seat - Outlet: RTB1009M side mount brackets")
Limited stock available at up to 40% off! Seats manufactured 2021 with an FIA Not Valid After (NVA) date of 2026. MSUK adds another 2 years to this date.
The RT4100WTHR is a wide and tall sized fibreglass race seat equipped with head restraint wings for enhanced safety. 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 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 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. The 4100 Series seats use Racetech RTB2009S or RTB1009M side mounting brackets.
