Racetech RT4129HRW Advanced Racing Seat - Standard Size (RT4129HRW-116)
The Racetech RT4129HRW Advanced Racing Seat delivers professional-level safety, comfort, and performance in a durable fiberglass construction designed for elite motorsport competition. Exceeding the demanding FIA 8862-2009 Advanced Racing Seat standard, the RT4129HRW is built for drivers who require uncompromising protection without stepping up to a full carbon-Kevlar shell. Trusted by Bathurst-winning teams and widely used throughout the Australian Supercars championship, this seat represents the pinnacle of fiberglass racing seat technology.
Constructed from high-strength GRP (glass-reinforced plastic), the RT4129HRW offers exceptional impact protection and structural integrity while providing a more cost-effective alternative to the carbon-Kevlar RT9129 Series.
