I have about 3K miles on the car and maybe 25-30% are track miles. I have noticed that the bottom of the seat on the outboard side in particular. The creases are still black and are not cracked or anything. I am 195 lbs and 6'2so I don't think I am terribly chubby. It seems to me they should last longer though b4 developing these. Is it my track miles accelerating thsi or is it common out there with just street miles? Thanks.
