No issues here, but I have 255/285 so more contact patch.

also running the bfgoodrich comp 2 sports. I did another review on them here awhile ago if you wish to read it. Just search for that tire. Had it at an autox track. Worked pretty darn well and a good amount of feedback. Youll certainly know when too much is too much. But you can take those corners pretty hard. A buddy of mine is running the same tires on his sport model. He likes them a lot too. They are a little softer in the ride and dont hop so much. I like that about them.

Contact patch is a function of the car's weight at each corner, not the tire size. When you change the dimensions of the tire, it changes the *shape* of the contact patch, but the magnitude of the contact patch (square inches of area) remains the same. A wider tire has a wider contact patch, but also a shorter one.

So a 155 tire and a 320 tire both 26" in diameter have the same contact patch in square inches? I don't think so.

Think so. the 320 will just have a really wide skinny contact patch and the 155 will have a long narrow contact patch. Now if you go down in PSI with the same weight you can increase the total size of the patch.
