The Circuit II QRT is a wider version of the Circuit QRT which was designed to provide addtional head and neck protection. 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 QRT includes integrated head bolsters to protect the head and deep side bolster for maximum lateral containment. 

What is QRT

Designed and developed at the Sparco OEM Composite Laboratory in Italy, QRT is a patented state-of-the-art technical process, based on aerospace technologies. QRT creates an unparalleled mechanical strength to weight ratio. This innovative production method generates the lightest fiberglass composite seat shells currently on the market; in fact, it guarantees a reduction in total weight of up to 30% compared to traditional production methods. The QRT seats approach the weight of a comparable carbon fiber seat at a lower price point.
