I've noticed a lot of what you're saying, Ryan. Especially the part about opposing weight transition and the tires responding slowly. However, part of that (for me, at least) is due to the extra contact patch I'm dealing with. If I was running OEM size I may not even have that issue.
I was running crap tires before these, so anything's a step up. I do feel more confident tossing the car into a corner, though; I just have to "learn" how the car responds to get the best possible lines out of it.
I'll find out tonight if the tires were part of my sorry launches last time at the track. I'm shooting for a 2.4 or better 60' - wish me luck!!
