I raced my friend who has a 2003 M3 convertable yesterday. We did a couple of runs. First run was a 40mph roll and we were dead even all the way until we shut down at about 115mph. Second run was in 1st gear at about 15mph. When I shifted I spun my front tires going into 2nd lol. same result, but I think I was starting to pull on him in the middle of 4th, right before we shut down.
He was really impressed so we went back to his house to see how his dad's Porshe Carrera 4S would do against me. We went from a 1st gear roll. We were dead even until i got into 3rd gear and he pulled 2 cars on me by 110 mph and kept pulling. I looked online last night and they so 12.8 @108. I am really happy with my car right now. All I need now is a dyno tune to work out some studdering issues and to see how much power I am putting down.
