Largest disc size behind 17" Avus wheels?

[shark_90]

I am currently using a 314mm A8 disc with Hi-Spec calipers. This was important as I was going to use my 16" Avus wheels as track wheels, but as I have brake fluid stains all over my 17" Avus wheels I've decided I'm going to use them on the track and use some other wheels for the road.

So bearing in mind that I'm going up an inch in wheel size, which discs are going to best suit me? I'd quite like for them to be a standard item and not specialist or cut-down to size, so I can buy them off the shelf.

about 330mm is largest you can goto on 17's. You can use the porsche setup with 323mm discs too

Looks like it'll be the 323mm discs off the A8 then! Cheers Greg

I've still got 330mm under 17's , I thought you could get 342/3 somethings under 17's, but I'm not positive

Its more dependant on the size of the calipers and the shape of the inside of the wheel if you go above 330mm discs and calipers

365 under a set of 17"s. As Greg says it is all to do with the size/shape of the caliper and the internal shape of the wheel.
On certain 17" Audi wheels it is possible to fit upto a 340mm diameter.
