Darren, a former 10.5 racer, recently made the move to radial tires into the Pro275 category. His crew chief made the suggestion that they should make the move. They fitted the car with radial and took it to Duckx Productions Lights Out at South Goergia Motorsport Park. Once they bolted on the radials, Rupinksi said he was in love and they have never looked back.
