Weird Tire Wear, educated opinions?

spearfish25

I've been noticing some abnormal wear on my front RE-11s. I'm hoping some of the knowledgable community members might have some ideas/suggestions. There are two wear patterns I'm noticing.

First, there is a lot of wear on the outer sidewall/tread junctions. It looks slightly scooped out like 'cupping' but it's consistent all the way around the tire.

Second and more noticeable, the outer tread blocks have heel-toe wear. If you look at the tread blocks on the top of the driver's side tire, the blocks are higher toward the front of the car and lower toward the back. I'm wondering if I overheated the tires on my track day and heavy braking deformed the tread. I never noticed this wear prior to my track day in 95F weather.

What do you guys think? I'll try to post some pics, but it's difficult to convey in photos.
