We told you a couple days ago here at the 5.0&SF blog spot that Jack Roush Jr. was joining the Mustang Challenge fray at the 45th Anniversary celebration. Well, he's not leaving the Koni Challenge behind, and he's picked up our friends and Moss Muscle as a sponsor. Peep the official release after the jump...

Jack Roush Jr., son of motorsports legend Jack Roush, has partnered with Moss Muscle, a leading Mustang parts and styling retailer, for the 2009 KONI Sports Car Challenge Series. Providing team support, equipment and promotional support, Moss Muscle will have a significant presence with the No. 61 car driven by Jack Roush, Jr. and Hugh Plumb during the 11-race series.

“The S197 Mustang is the perfect platform for the KONI Challenge Series and we wanted to associate ourselves with a leader in the S197 aftermarket” said Roush. “Moss Muscle has the widest selection of options for customizing, performance and styling, and they’re experts in the field. Like us, they’re passionate about the car and we look forward to their help this season.”

“Jack and the Horsepower Ranch team are the perfect fit for us” said Moss Muscle program manager Kevin Flint. “These guys are smart, aggressive and out to win races. So anything we can do to keep their Mustang at the front of the pack, we’re ready.”
