2008 was the inaugural year for SuperCar Races. In 2008, we had many successes, including the running of the Mopar SuperCar ShootOut Series, our relationship with NAS, running a schedule that compliments both series, our partnership with Carlisle Productions to bring factory appearing muscle car racing to their premiere events and our partnership with the Make-A-Wish Foundation®.
The Participants, Sponsors and
Fans of Supercar Races don't want to be known only as Musclecar enthusiasts,
but want to be known as a group that gives back to the hobby and the community.
We have championed many issues and are solidifying the SuperCar Series
as the concrete foundation to the style of racing we enjoy most.
We are excited to officially welcome Pure Stock into the SuperCar Family. We want to give our current and future Racers a venue to Showcase their Pure Stock MuscleCars. SuperCar Races prides itself on being the leader in American MuscleCar Racing. In 2011, We will be featuring a venue for all Legal Pure Stockers to take part in. Our Rules will be posted over the next couple of months.
We are moving forward at a rapid but cautious pace. In the next couple of months, we will appoint a Rules Committee that will represent the majority of the Pure Stockers. Our Goal is to give the Pure Stock community a series of events to take part through out the season. This new series will enforce all rules with NO exceptions.
Welcome Pure Stockers 1955
to 1979!
