BMW 6 Series - Tech Talk E24,E63,E64,F12,F13
i'm back again, now with a 2014 640d
After our recent drive on the M6 i noticed the front disc is badly warped.
i've been looking around and for some reason there are very few choices, i have found 2 that seems decent which is Brembo or Zimmermann black Z
has anyone have any experience...
