Protecting and supporting the human body in the right places and keeping all parts of the body in the same relationship to each other will help minimize injury and greatly increase chances of survival. The design and structure of the seat is perhaps more vital to survival than even the harness. Tests show that in a frontal impact only around 20% of body movement comes from the belt stretching. The remaining 80% is from the body not being contained within the seat. The ability of the seat to absorb crash energy lessens the amount of it that the body has to contend with. And in the case of multiple impacts the belts and seat will continue to deform, making the quality and strength of the structure around you even more vital.

Racetech 4100 seats feature a lighter fiberglass shell than 4009 seats and have the option of a seatback brace included in the shell structure. The 4100 was designed to be wide enough in the shoulders to suit an athletic build, but narrow enough to fit in most cockpits. Racetech designs their seats with support in critical areas to minimize fatigue and improve driver comfort and confidence. As a fiberglass seat designed under FIA 8855-1999 regulations a seatback brace may be required, depending on your series rules and safety standards. The 4100 has reinforced threaded bosses inside the seatback.
