Are the sidewalls bulging? Got good clearance all around? Maybe if it's not too much hassle for you, could you repost here after your Aug. 13th run and give us a report??
The sidewalls are definitely bulging a bit. I've seen pictures of various other 225/50-16 tires mounted on the stock wheels, and these look similar.
Hopefully I'll be able to notice the difference in tire grip. The front sway bar will probably mess up the comparison of turn-in response and handling in sweepers, since I already noticed a big difference with just the bar on RE92's in normal driving.
