I'm wondering if it's due to rolling over onto the stiff sidewall on the road course.

Hm. The F/R wear is usually on older cars when I've seen it. My 540i had issues with it around 200,000 miles due to worn out bushings. I'd guess the stiffer sidewall might be pushing the suspension a bit harder. Are you on stock suspension?
