Hi Folks, I am looking for cross drilled brake disks to replace my front disks on my 98 S4. I have found replacement rear disks no probs, but I'm struggling to find fronts. Are the front disks on the S4 the same as the S8?? Or are they the same as one of the A8 range? I can find black diamond cross drilled disks for the A8 and S8 models for reasonable money and would like to buy these if they will fit, any info muchness appreciado. Gaz.
