What gear ratio for a street car w/occasional track use?

You have the data of highway rpm now, what can you live with? Go drive the highway in 3rd gear and do math to calc current final drive with the 3.55. More gear will drop et if your car hooks. I run a 3.91 but got lucky and picked up a used GVOD. Driving 50 miles to the track gets old and the GV knocked off 400 rpm at cruise.
Are you disappointed in track performance? More to good et than horsepower. Post up your combo, more ways to get a car quicker than just gears. Do you have a baseline time slip you can post.
