DGR Performance or Excessive Motorsport Performance
Been trying to get a hold of the guys at DGR Performance ( formerly Kauffman's and SGS Auto ) but have not heard back from anyone via email or phone after two weeks. I'm wondering if they're still in business?
With that said, has anyone had any experience with Excessive Motorsport Performance in Manassas Va?
