A good driver can have fun with any car regardless of the number of doors. That said a four door sedan is still a four door sedan and generally equated with being a dull, boring family car even if it does possess unexpected performance capabilities. Back on subject, in my original post I suggested going to a legal drag strip to settle their dispute. In addition to the reasons I put forth then, there is another practical reason for doing so. You don't have to be quicker to win, even if you run heads up. If you have a better reaction time you can still beat the other guy to the finish line even if they are a little quicker. Obviously the difference can't be too great in order for this to work. My guess is the the BMW guy has never been to a drag strip or at least not run on one. If this is the case he won't be familiar with the " Christmas Tree" starting system. This is a major disadvantage and we want every advantage we can get. If you wait for green you WILL be late. If you're late there is a good chance you will panic and spin the tires. There is one bit of advice I would change. If the OP has a manual transmission it might be best to use a 15x10 wheel instead of a 17x10. The taller sidewall should help him launch the car. It would really help if the OP went to the track at least twice prior to the "BIG DAY" and learn the lights and practice his launch technique. The BMW may be coming on strong at the lights, but if the OP gets there first it's still a win and that's what matters.
