The latest Sparco Rev GRP Racing Seat features an all new reinforced fiberglass shell that has been stretched slightly wider to accommodate a larger range of drivers. The reinforcement ridges designed into the seat increase strength and minimize flex to keep the driver supported. Non-slip fabric incorporated into the shoulders help keep the driver in place, while an all-new split-leg bottom cushion helps increase driver comfort and mobility. High-wear fabric sewn into the seat edges help keep the seat looking new year after year.

The Sparco Grid Racing Seat is designed to provide the ultimate combination of lateral support, ergonomics and safety. Starting with an all new shell with extra deep side bolsters, and supportive shoulders for excellent lateral support, the Grid makes use of Sparco's new LF (Lightened Fiberglass) Technology. This aramadic fiber-reinforced fiberglass shell makes use of a new manufacturing process that lightens the shell by an average of 3-lbs per seat. This 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 day
