Johns attended the
University of North Carolina at Charlotte while an employee at
Team Rensi Motorsports. He graduated UNC-Charlotte with a
Bachelor of Science in
Mechanical Engineering. At the same time, he was promoted to Rensi's head engineer. In 2007, Rensi turned to Johns in driving their No. 25 car to fill in for NEXTEL Cup driver
David Gilliland when his Cup and Busch schedule conflicted in 15 races, sponsored by
freecreditreport.com. Johns had two top-twenty finishes and ended the season with a 44th-place finish in points. Losing not only both sponsors but Gilliland as well, who had mutually left due to the struggles of
Yates Racing, Team Rensi downsized to a one team operation. During the offseason, Johns left Team Rensi and signed a sponsorship deal with family internet portal havfun.com. He and havfun were to compete in the Craftsman Truck Series for Wyler Racing in 2008, but the sponsor money never materialized and the deal fell through before
Speedweeks, leaving Johns without a ride. ==Motorsports career results==
