10 Speed PP1 with just PP2 tires is enough to smoke the Supra around a road coarse, or Ford can Option out a PP2 with 10 Speed Auto.Thanks for posting, I always enjoy seeing these types of comparisons, even though I'm not sure these quick one-track tests always completely show their full performance. The difference between the two was .2%, which seems like it would be attributable to any minor miss on any given attempt (missed a perfect shift, didn't hit an apex just right, etc.), so I think based on that it's tough to say one is clearly faster than the other on this track. I'm curious if there would be a bigger difference on a different track.
It's interesting to see how much faster the PP2 was, and I'm guessing that was mostly the tires, but I'm sure the other changes help as well. PP2 owners should feel like they got their money's worth from that .
