I have C4 ZR1 rears wheels that Im using for drag radials. I was wondering if the C4 ZR1 offsets for the fronts will fit on the C6 fronts.

They'll fit if you have the "base" brake rotors. If you have Z51 rotors, they won't fit

I have 18x8.5 c4 ZR1 replicas for the front that will clear z51 brakes. I am selling them with basically brand new tires if you are interested. They are painted flat black.

PM me an offer...

The base C6 and the Z51 C6 has the same rotors, I have read many with the opinion that its different but my C6 is a 2008 Z51 and I changed my brakes to the Z06, my old brakes was installed on my friend base C6 and after the installation I went to the shop and realized the brakes was the same size. Both the calipers and rotors was the same, my friend's car was a base 2007 A6.
Now if there is something you guys know that I am not aware of, it has to be the base C6 MN6 compared to the C6 Z51.

Z51 rotors are drilled/ slotted and are larger. The calipers are the same, however , the brackets for the base are smaller.
