The Racetech RT4100HR is a Series of fiberglass race seats equipped with head restraint wings for enhanced safety. We have focused on achieving a lightweight seat shell with optimized geometry. Our back-mounted technology has trickled down from the 119 and 129 Series, giving you the option of bolting the back of 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. Breathable Spacer fabric, parallel sides, and pronounced thigh support round off the features of this accomplished motorsport seat. For the taller driver, we have developed the RT4100THR, which utilises the RT4100WTHR shell but has added high-density foam to the sides up to the shoulders to bring the internal dimensions of the seat inline with a standard-width RT4100. This seat is 60mm taller than the standard size. For the larger driver, the RT4100WTHR is 60mm taller and 40mm wider. For 2026 we have introduced the RT4100SHR model, which is 50mm shorter than standard, this model is not FIA Approved. The 4100 Series seats use Racetech RTB1009M aluminum side mount brackets or RTB2009S steel side mount brackets. Perfect for that Drag Race Outlaw, No Prep Car or Door Slammer when you need to be safe and comfortable.
