OE Style Custom Fit Seat Covers install quickly and easily with Fia's patented Super-Grip technology. This is an advanced concept that utilizes a slip-resistant fastening system that uses belt and buckle fasteners, zippers (on some models) and Velcro. To ensure these seat covers grip the cover to the seats for a tight snug fit. All Fia seat covers are constructed of highly durable tweed fabric that is flame resistant, will not fade from sunlight and maintains the color without fading or running. They feature a foam padded back support for added comfort. These seat covers are available in charcoal (charcoal center panel with black side panel), gray (light gray center panel with dark gray side panel) and taupe (taupe center panel with mocha side panel).
