I love complaining about my altitude too! The track I run at is right at 4,100' and in the summer with the 100*+ weather makes it even more exciting. Keep one thing in mind when you go to the track, the thin air makes a HUGE difference with your times, so don't be dissapointed if you run in the 15's. When I first bought my car, with exhaust and 3.55's the best I could muster on street tires was a 15.03 @ 92.3 and that was with the back seat and passenger seat taken out. I now run a 13.4 @ 102 in hopes of my 12.99 with stock heads and cam by spring. One site that may help you out with the conversion is:
