I will never touch carbon lorraine again. I used a set on my 172, 1 track day at bedford and a bit of road use. Here's the result

Bloody hell, never seen anything like that on CLs before. Maybe there was a bad batch? I've had mine for about a year, had them out to do a brake clean up last week and they look good as new.
