I need new rotors for my 2000 a6 2.7 and am having a difficult time finding any real definitive information. It has the hp-2 brake system. I found a set of rotors and pads on eBay but it says they are for the girling brake system. They are 321mm/30mm. I know I need 321mm diameter. I just can't find out the depth that I need. Basically I just need to know if those rotors will fit properly on my car. Thanks.

 

If it's a 321mm rotor and it has 8 pads (4 per caliper) it is this one.

Thank you. That is what I figured but I wanted an informed second opinion.
