Improvements such as torque boxes and 10 gauge boxed rails strengthen the previously weak design elements of the factory chassis. The whole chassis sits closer to the body for a clean finished appearance. Rear framerails have been narrowed to accommodate a 12″ wheel with a 345 section tire. The entire chassis has been designed front to back with the emphasis on modern day performance requirements and serviceability. The FAST TRACK chassis also allows a lower, more aggressive stance that features true drivability and a packaging design that maximizes ground clearance for enjoyment in all road conditions.
