My 98 ws6 = heavy , ran a best of 13.6 last wed at the trails. I spun the tires half way thru first and nearly got sideways going into second. My t/a is a a4 with 140,000 miles with all the factory optoins . I will be out there this Wed again trying to best my time. Come on out Bam. I ran a 01 gt there, he had a cold air kit and a few bolt ons and only could run 14.10's.
