The S5 is a vehicle with little need for modification but it's also one of our favorites to work on. Lucky for us, it's also one of the favorite cars to be upgraded! This particular S5 came to us with a few items looking to be crossed off the to do list, starting with H&R springs, a JHM clutch, GMG sway bars, and an AWE Tuning exhaust system. Now this Audi is several big steps higher on the cool scale.
