It's a good thing that I said something then. Kumho's aren't drag radials. Those are DOT road race/auto-x tires. Sidewalls twice as stiff as normal street tires. You would have loved driving to and from the drag strip, but on it would have sucked.
If you have a stock exhaust on your car, then that is most definitely the restriction. The best ET gain I made was when I put the 2.5" high flow cat and 2.5" exhaust on the car. I went from 16.3s down to my first ever 15 second pass. Little tweaks and a couple more mods have gotten me down to the 15.6s.
98Talon - I wish I had your chassis. 2600lbs and I'd already be in the 14s. But that's going to be one of my projects for this winter. Weight reduction.
