Here's the results:
All testing was done in the same location, 78 degrees ambient, same direction, 3 runs each
I made the comparison even more accurate by swapping my father's 17" S-Spoke wheels on to my car instead of driving two different cars.
0-60mph = 7.37, 6.74, 6.85 seconds
60-0mph = 127, 125, 133 feet
0-60mph = 6.57, 6.67, 6.52 seconds
60-0mph = 115, 111, 113 feet
Interestingly, but not surprising, it took more power to launch the 17/run-flats. I was launching the 16's around 3200rpm to get the perfect run while it took about 4000rpm to launch the 17's. It's obvious to me that the rotational mass was the factor to get moving quicker (this is also why the first run on the 17's was significantly slower, it bogged a little at just above 3000rpm).
I ran the 17's first to insure that brake fade would not favor the 16's. Turns out the brakes cooled plenty in the tire change, although they were very hot when I changed after I was finished.
It is VERY easy for me to now see where the magazines could get higher 0-60 times. I've launched this car MANY times and it's well broken
in, two factors that magazines do not have right now.
I was extremely happy to see the 111 foot braking number, that's quite impressive.
Again, take these numbers for what they are, a comparison via a G-Tech.
