Margo Wilder ran True Street in her '98 Formula Firebird. The LS1 under the hood has a hot cam, a ZO6 intake, Hooker headers, and an Ed Wright tune. Weld wheels wrapped in DOT Mickey Thompson drag slicks provide enough traction to lay down 1.7 60-foot times. Not only does her car run mid-12s, it does it with a full competition audio system in the interior. Wilder says she loves her tunes. It took her three years to build the car and this is her first year competing with it.
