The Sparco Circuit II QRT is a wider version of the Circuit which is an ultra-light competition seat specifically designed for circuit use. Made from aramadic fiber-reinforced fiberglass with all-new QRT Technology, the Circuit II QRT features a wider shell to accommodate a larger driver. The Circuit II LF includes integrated head bolsters to protect the head and deep side bolster for maximum lateral containment. This seat can be used with a Hans device for even greater protection. The ultra-light shell is then wrapped in an impact-absorbing and fire retardant fabric that helps hold the body. The Circuit II QRT is FIA approved.
QRT Technology gives an unparalleled mechanical strength/weight ratio for fiberglass composite racing seats. QRT Technology gives an average weight savings of 30% when compared to standard fiberglass technology. The main benefit is that QRT seats approach weight of carbon fiber seat at the price of a fiberglass composite seat.
