Updated with Sparco's patented QRT Ultra-Light Technology, the Sparco Grid Q offers an average weight savings of 7lbs per shell, approaching the weight of a carbon fiber seat while keeping the price of a fiberglass seat. Designed to provide the ultimate combination of lateral support, ergonomics and safety, the latest Grid seat features updated padding for a much improved fit. Extra deep side bolsters, and supportive shoulders for excellent lateral support, the lightweight shell is wrapped with impact-absorbing foam and covered with fire retardant, self-extinguishing fabric. The seat is finished with a unique padding system that is made up of several individual pads attached by Velcro. These pads not only allow for a customized fit, but create natural ventilation channels on the seating surface for unsurpassed cooling on hot days.
