RSR is a classic car and truck shop founded by Zach Simms, who has been working on automobiles and engines for over 20 years. Zach's passion for classic cars and trucks was inspired by his Grandpa and Dad, Ralph Simms, whose names make up the "RS" in the shop's name. RSR quickly gained notoriety on Instagram from the C10 build known as "Black Dice".

Growing up in southern Illinois, Zach spent countless hours working on cars with his family, learning the ins and outs of these beautiful machines. He has been living in the Middle Tennessee area since 2004 and recently founded RSR to pursue his passion full-time.

At RSR, we are committed to customizing classic cars and trucks with class and integrity. We focus on details, efficiency and innovation without sacrificing quality in every build.

From suspensions, engines, and modern upgrades, RSR has the expertise, connections and resources to get your classic car or truck customized. Zach takes pride in his work and is dedicated to providing his clients with the highest level of service and quality.

We currently focus exclusively on General Motors rides from 1948 to 1972
