Racetech RT4129HRW Advanced Racing Seat

RT4129HR Series

The Racetech RT4129HR delivers the professional-level protection of the flagship 129 Series in a reinforced fiberglass composite construction. Sharing the same ergonomics and safety architecture as the RT9129HR, it is engineered to satisfy the demanding FIA 8862-2009 Advanced Racing Seat standard while offering a more cost-effective solution for professional GT, touring car, endurance, hill climbs, and international motorsport.

Its reinforced composite shell, integrated back mount, and FIA-approved energy-absorbing foam work together to improve crash performance while reducing driver fatigue and enhancing vehicle feedback.

Why Choose the RT4129HR?

FIA 8862-2009 Certified

Engineered to withstand dynamic impact loads approaching 70G, meeting one of the highest safety standards in professional motorsport.

Reinforced Composite Shell

Strategically positioned carbon and Kevlar reinforcement provides exceptional structural strength while efficiently managing crash energy.

Biomechanically Engineered Support

Ergonomic shell design, integrated head restraints, and Racetech's signature square shoulders improve driver stability while maintaining ideal harness and FHR positioning.

FIA Energy-Absorbing Foam

Strategically placed energy-absorbing foam in head, shoulders, ribs and thighs helps reduce localised impact loads.

Integrated Structural Back Mount

The included back mount increases installation rigidity, improves chassis feedback, and forms part of the FIA 8862-certified installation for GT3.

Ducted Air Cooling Capable

Scientifically, the most efficient way to cool the body is through air circulation to the lower back. The integrated rear air duct allows easy connection to our blower motor or another air source, helping reduce heat stress during endurance races and high-temperature competition.

* To comply with FIA 8862-2009, the 129 series seats must be back-mounted to the rollcage at shoulder level. Back-mounting improves seat strength and stability during an impact, increases driver 'feel' and reduces driver fatigue; see the explanatory video here.
