  3. Hi I have a M2CS I track heavily in the 6 months I have owned it. The front brake rotors are now badly cracked, some over 10mm however not to the edge yet. Is there a spec guide to BMW rotors as to how far they can crack before needing replacement? I have ordered some semi floating grooved rotors awaiting delivery but am a bit worried I should stop using it until the new rotors arrive. Also I am told there is a genuine BMW brake duct cooling system although I can't find where to order one. Can you fit one of the M2CS racing front spoilers onto a street CS? they have extra cooling vents which are not on mine which is stupid they don't just put them on all CS cars. If they would fit where can you get one? thanks for consideration Jim
