Racetech USA 4100 Series Seats

Racetech USA 4100 Series fiberglass race seats focus on achieving a lightweight shell with optimized 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. Racetech's 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 molded base cushion allow a range of drivers of varying heights to fit. Marine-grade vinyl, parallel sides, and pronounced thigh support round off the features of these accomplished motorsport seats. They're ideal for an entry-level club racer, track day car, or street/strip drag car. FIA 8855-1999 approved. The 4100RT is standard size. For the larger driver, the RT4100WT is approximately 2.25 in. taller and 1.5 in. wider. And for those wanting a seat with head restraints, the RT4100HR and RT4100WTHR complete the 4100 Series. The 4100 Series seats use Racetech RTB1009M aluminum or RTB2009S steel side mounting brackets.
