Hmm, the temps here aren't very high and I've always had relatively fresh Corsas but I've never heard them howl. Generally I can get them to a point where the car will under/oversteer predictably and I start using the throttle to steer the car in the corners. I do run lower pressures then what Lotus suggests (I run 32/35 cold) and the temps/pressure does climb a lot but I only had issues with crowning in the rears when I ran 39 cold.
I don't know if they're really worth the extra cost, there are a few different Toyo Proxes tires (requiring smaller wheels) that would perform as well for less cost.
