Does anyone know the minimum disk thickness?
 

Front disks, standard CSL set up.

I've been told they are 28mm new and 26.4 minimum, but I would like someone to clarify.

That is correctomondo;)

Best price for new discs is bmw mini parts think i paid about £540 for front and rears or £400 odd if you can get them vat free.:whistle:

My rear AP disk after 2 years .

If you see this it is almost time to change :smokin:
