Why Choose the RT9119HR?

Lightweight Carbon/Kevlar Construction

The proprietary hybrid carbon/Kevlar weave shell delivers an exceptional strength-to-weight ratio while managing impact energy through controlled structural compliance.

Proven 129 Series Geometry

Developed from Racetech's flagship professional 129 Series seats, the ergonomic design provides exceptional support, containment, and comfort across sprint and endurance competition.

Biomechanically Engineered Support

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

Energy-Absorbing Foam

High-density foam surrounding the head and torso reduces localised impact loads while improving comfort during long race sessions.

Integrated Back Mount Capable*

With our unique integrated back mounting system, the seat becomes part of the vehicle structure, increasing installation rigidity, improving chassis feedback, and satisfying FIA 8855-1999 mounting requirements, except for the Wide model.

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.

Brackets and Mounting:

- Side mount to the floor using Racetech RTB1009M 5mm aluminum brackets (please select above when ordering).

- Back mount using the RTB3115B or RTB2115B in conjunction with RTB2005C. The RTB2115B is a 5mm aluminum bracket that bolts directly to the shoulder beam of the seat. The RTB2005C clamps bolt to the RTB3115B or RTB2115B (once holes have been drilled) and come in 3 variants: either a 1¹/₂ (38mm), 1⁵/₈ (41mm) or 1³/₄ (45mm) ID to suit the rollcage tube diameter in your vehicle. Please select your preferred clamp diameter above when ordering. 

* To comply with FIA 8855-1999, the 119 series seats must be back-mounted to the rollcage at shoulder level. Back-mounting can be achieved using parts RTB3115B or RTB2115B and RTB2005C; see instructions here. Back-mounting improves seat strength and stability during an impact, increases driver 'feel' and reduces driver fatigue; see the video here.
