The Sportline RRX seat is a favorite among customers worldwide because of its looks and incredible comfort. It is a perfect blend of aggressive lateral bolster support but with the comfort of a daily driver. Whether you are on the street, the track, or off-road, you can’t go wrong with the RRX. The new Sportline series from Corbeau factors in feedback from customers all over the world to come up with a look and feel that is second to none. Unbelievable comfort, style, and support are put into every inch of this seat. It features top of the line injection molded foam, strategically placed bolsters to support you in just the right places, and harness belt capability. The Sportline RRX seat is available in our Jacquard Cloth and Black Vinyl/Black Carbon Fiber Vinyl. The Jacquard cloth is known in the aftermarket seating industry as being among the most durable of any cloth material. The RRX has a seat base height of only 2.5 inches. That means is if you set the seat on the floor, the distance between the floor and where you would sit is 2.5 inches. Comparatively speaking this is a thin seat base, which is ideal for minimal headroom applications or for drivers wearing helmets. Please note that because of the design of the RRX, an inflatable lumbar support and a 5th slot (Anti-Submarine Slot) cannot be added to this seat. The RRX does, however, have great lumbar support so don't let that be a deal breaker. As a rule of thumb, the RRX will fit up to a 38-inch waist.
