Pretty fun discussion on tire diameter differences though. "Twitchiness"?? 
All 987, 997, 981, 991 run 1" smaller diameter in front than the rear. It adds a little rake to the car so there is more weight on the front tires. This helps to generate excellent car balance in the corners. The idea that all these cars are "twitchy" because of the different diameter has never been discovered until now. 
If your car feels twitchy, it needs an alignment. |
Well you learned something today again then. On a alignment for street car, the tire rotation makes a big difference when you decide to go for a spirited drive. No my car does not need an alignment as I can fell the twitchyness changing the front tire to a smaller faster rotating speed.
People that race, align their cars much different then street cars. Alignments good for race cars are not good for street cars, if you want to have proper tire wear.
"All 987, 997, 981, 991 run 1" smaller diameter in front than the rear."? You are completely wrong in this statement.
