Brought my 2015 Mustang GT Premium automatic in for a suspension upgrade. The shop handled the procedure smoothly, ahead of schedule with superb results! Overall, it was a great experience and they executed a tough job in a short time.They also gave additional expert advice before and after, ensuring that I understood the implications of my request, the technical changes and limitations.After testing the car for months, the work they did was and is absolutely superb. I'd recommend them to friends and family as the best performance car and truck shop in Roseville. Thanks.
