Wow Ed, interesting info (although about what I feared). Was the track there or was it greasy? I wonder if it didn't spin, it might have shook.

I'm pretty locked in on 26" tire too, running a 26-9 slick now, but also going to try and get a 26-11.50 QTP under there (10" wide and DOT).

Was anyone else seeing the MPH differences? Since I dropped the nose on my car this year I'm back to seeing a difference, but never that much.
