Brake Rotor Sizes
 

Hello everybody. I'm trying to figure out the dimensions for my brake rotors. It's Audi A6 2.7T 2000, and I know there are different sizes on this model. Could you tell me how I can find the right size for the rotors both front and rear. Thanks!

Option One, take the wheels off and measure.

Option Two, call the dealer and run the vin.

Sorry to be blunt, but those are the only sure fire ways. With that said, here is what you need to measure.

For the fronts, the size is 321x30mm, but you need to check the hat offset. It is either 16.7mm or 22.7mm.

The rears are a bit more complicated. There are 2 different diameters available. In addition, the larger one has two different offset.

So the best bet is go out and take the wheels off.

Take the wheels of and get the part numbers from the rotors.
Or PM me your vin and i will look it up.

Thank you for the answer. What exactly should I measure in rear rotors? One online store that I found gives dimensions for the rear exle width and wheel bearing together with rear rotor sizes. Should I consider these sizes too? Does it matter if car has standard or sport suspension?

The rear rotors are either 245 mm or 255 mm. 245mm has one offset, but the 255 mm has either 1.5" or 1.75" offset. ecstuning has a good description of how to go about identifying the correct rotors.

I tried ecstuning and their site was not very user friendly. Couldn't even find basic rotors and brake kits.

Don't they know that websites have very little time to grab our attention with easy to navigate shopping? I went elsewhere.
