Our RT4339 is made from a carbon-reinforced fibreglass shell structure and mated with a massive 75mm of high-impact energy absorbing (SFI Approved) foam and 25mm of energy-absorbing comfort foam to achieve a full 100mm foam containment solution with an emphasis on head protection. These materials and their dimensions are currently used for the same application in NASCAR seats. The shell structure of the 339 is built similar to our 129 series has surpassed simulated impacts of more than 14kN to the pelvis, 11kN to the shoulder and 7kN to the head. Click here to download seat mounting instructions for Speedway NZ use.
