The Coyote-engine-swapped 2004 GT gets a chassis and suspension upgrade to handle the 400-plus horses the 2015 F-150 Coyote V-8 puts down. Tony Angelo and Jimmie Caldwell replace the entire rear four-link suspension with a Griggs Racing torque arm setup with QA1 custom coil-overs. Then, they upgrade the whole interior and set some fast lap times at Willow Springs!
