If you can, try to do a before/after GPS correction. I did the after, but I wish I had done the before. I know I am getting a 2% gain right now, but I don't know if I was already +X% to begin with.

why wouldn't you go below spec on the drive tires? just so you wouldn't screw with the odometer?
Also, don't you think the reduction in wheel contact with the road coupled with the decreased rolling resistence of the B381's would well outdo the loss in mileage due to increased rpms? I would only have to do 27 more revolutions per mile....
And lastly, since you're in my area (I'm in west L.A.) would you like to get together to work on modifying our cars for better aerodynamics... I really don't know anyone who's willing to work with me on this. I realize it's an odd suggestion and I understand if you're weary about meeting a stranger from online
