I'd have to agree with you wagonracer. It's probably the tires stressing from the inside out. I wouldn't think it to be something aerodynamically because my sti is a lot quieter at the same speed my 06 wrx was at while being noisey. I wish there was a decent track....let me correct that. Decent asphalt track near me. I'm not trying to drive the susquehannock trails that Rally America drove in June. Correct me if I'm wrong. Since you seem like your fairly track smart. Don't most tracks require you to run nitrogen in your tires if your planning on exceding 125 mph? Because nitrogen lowers the chance of a blow out due to heat expansion. That's what I've heard, just wondering if it's true.

No, running nitrogen is just a way to control your pressures, so that they remain more consistent over the course of a race. You need to purge the tires completely, then run only nitrogen for it to have any benefit.

Tire pressures rise with the heat that is created with the friction of turning, braking and accelerating, not top speed.
