Racetech RT4129HRW Advanced Racing Seat - Wide & Tall (RT4129WTHR-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. Its advanced ergonomic design delivers outstanding comfort and support during long race stints, helping reduce driver fatigue while maintaining precise vehicle control. Included side and back mounting brackets simplify installation and ensure proper compliance with FIA requirements when mounted according to Racetech specifications.
