4KQ Hubs: Front vs. Rears and bearing sizes

[spectrum]

There are a few differences aside from the bearings.
 
The front rotos are slightly larger diameter and vented, the rears smaller and solid. 
Also, the offset of the rotor is different.
The front hubs are unique to the 4k quattro and non quattro. The rear hubs interchange with the 80q/90q/Cq and I _think_ the 100q
 
What is it that you are trying to swap?

Thank you all for your responses.

For Todd:

Todd, do you mean the front and rear rotors are the same but the wheel bearings
are different size due to their respective housings in the strut?

Are the front bearings 68mm?

Meaning front hubs are different than rear hubs or simply the bearings are
different size?

Hi all,
 
Are the rear hubs and wheel bearings on the Audi 4KQ the same as the
front's?
 
A search on AutohausAZ.com for the 4KQ's front wheel bearings revealed a
68mm size with part #s 321498625D and 823407625B.
 
As for the rear wheel bearing, it showed a part # 33411130617.

Thank you in advance
