The Evolution X was inspired by the C5 and C6 Corvette and any vehicle with limited space. As most Corvette owners know, seating options are limited due to the small cockpit area of the vehicle. We made the angle of the back at what we feel is the most comfortable angle for a daily driver or where most people would recline their seats. Whether you drive on the street, the track, or offroad, you'll notice how the Evolution X virtually eliminates body shifting, meaning your body won't get fatigued. Please note, the Evolution X also comes in a reclining version called the Evolution.
