Announcing the all-new Racetech 4100 Series! The RT4100 is a standard-sized fibreglass race seat. Racetech 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. Parallel sides and pronounced thigh support round off the features of this accomplished motorsport seat.

Cover options include Breathable Spacer fabric (Cloth option) or Marine Grade Vinyl (Vinyl option). The Vinyl is designed for offroad and open vehicles where the seat is likely to get wet.

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 Racetech RTB2009S or RTB1009M side mounting brackets.
