Having done some highway driving now I have confirmed that these numbers are pretty close for my car with the stock 18" tires, 6 speed man and 3.73 gears. Thanks for posting.

Thanks for uploading the chart. It's pretty helpful. My GT Track pack with 3.73 is on the way, and I was wondering what the top speed is in 2nd before you hit the the rev limiter.

Thanks for posting the spreadsheet. I have one I did several years ago and have modified it as I changed cars. When you are looking at analog tach and speedo it is easy to be a little off from your calculated numbers. This is especially true where the instruments only sweep 180 degrees as ours do.
