Racetech 4100 Seat
The RT4100 is a standard-sized fiberglass race seat. We have focused on achieving a lightweight seat 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. 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 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 larger driver, the RT4100WT is approximately 2.25" taller and 1.5" wider and for those wanting a seat with head restraints, our RT4100HR and RT4100WTHR complete the 4100 Series

Answers to common product and project questions.
How do I confirm fitment?
Share your chassis, year, and intended use. We’ll confirm mounting, clearance, and any vehicle-specific brackets before you order.
Are partner parts returnable?
Most curated components can be returned unused in original packaging within the stated window. Custom or cut parts are final sale—confirm before ordering.
Do you help with installation?
Yes. We can advise on mounting, harness routing, and shop selection, or take the install in-house when the project calls for it.
Lead time and shipping?
Lead times vary by brand and configuration. Contact us for current stock and shipping estimates before you need the part on the car.
