When Duncan first brought his 2007 Shelby GT500 to us, it was a bone stock 7,500 mile car. Being a car guy for a long time, the days of keeping his car stock had come to an end. He wanted to do some track days and wanted more power, so we set him up with a full Cortex racing Xtreme-grip system with torque arm. To take care of the power side of things we added a JLT Performance carbon fiber intake, Metco pulley and idler, and a tune. We have many more plans in the works for this car so stay tuned.
