This is what both my rears looked like after last weekend auto-x. It wasn't
even hot outside. Is this an indicator of anything particular I'm doing wrong?

About the only abnormal thing on the course was a long 180 that was not
quite a hairpin but I had the gas pedal to the floor for the whole last half of
it. Basically with a 2.3 and limited slip and my setup, no possible way to spin
with foot on the floor.
