In its own right, the Audi A5 is one of the most eye-catching cars you can just roll right off of the dealer lot. Now, throw in this RS package from OSS Designs and watch your gentlemanly car turn into an edgier, more dangerous version of the German coupe. Beginning from the ground-up, OSS Designs first went with a set of 5-spoke Vossen Wheels, followed by a set of lowering springs, a new front and rear diffuser and bumper, and continuing up to the new color-changing LED and blacked-out finish headlamps. Adding additional aerodynamic and aesthetic improvements, a new ducktail rear spoiler commissioned by Protech Bodywerks as well as wider rear fenders with air intakes to help slow down the speed produced from the 444 horsepower 4.2-liter naturally aspirated V8, controlled through a 7-speed trans. After all is said in done, you wouldn't want to see this car in your rear-view. Instead, view it in the video and shots after the click.
