Hi,I have just noticed some small cracks on my Performance Friction discs kit,some of them I can catch my finger nail on,is this okay to drive and just keep an eye on or are they for the bin? they are still well within spec at 27,50mm thickness,thanks for the help.

I've had this before with stock discs on my 182. I believe this is normal on discs that have been used on track

The advice I usually see is unless if it reaches the edge of the disc or it’s very deep then don’t worry about it

Thank you guys will just keep an eye on them, certainly don't want to fork out 800£ for replacement discs.
