They are 380mm front and 370mm rear if that helps Bryce, I dont believe they are much better than the CSL brakes though although they M5 brakes are truely awesome on the road, I think I would go with the 6 pot AP's myself.
Don't bother. My mate has changed the OEM brakes on his E60 M5 for a BBK. They were crap on the track, loads of fade and when they were removed they weighed a tonne!
Spend your money on braided hoses, fluid & uprated pads if a BBK is out of reach at the moment.
Just throwing out there. Was some discs and calipers on ebay for £500 and thought if they're fit for stopping a 1.8tonne car, then surely they should be good for the CSL.
It's more the repeat performance that you're after though I assume? OEM setup isn't that bad at stopping the car a few times, it's when you lean on them again and again that they turn to mush :119:
i believe all factory standard BMW's have single pot calipers - its been a bone of contention for years - they wont go back and admit they are crap! IIRC a BMW BBK is availiable as a dealer option
