I sure would hope the new car (with an extra 80 HP over the old car) would be able to drop at least 13 seconds on a 13 mile course.
that is true! I agree...tires make a world of a difference...i could automatically feel the difference from riding in a stock e46 m3 with stock setup...and my friend's m3 with 245/275 michelin ps2s...it was literally night and day.
