Racetech RT4100 Series Racing Seat

2027 Expiry

The Racetech RT4100 is a standard-sized fiberglass race seat. 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. The Racetech 4100 Series patented back-mounted technology has trickled down from the 119 and 129 Series, giving you the option of fixing the seat to the roll bar or cage at shoulder level.

The large harness guides and a removable molded base cushion of the Racetech RT4100 Series racing seats 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.
