will oem 18" wheels from a 04 05 a4 ultrasport work on my 02 a6 2.7t car? i remeber reading that the calipers are bigger on the the 2.7t and 4.2 a6's so i want to make sure these a4 wheels will fit befor i buy them, also if someone has a pic of a a6 with the 04 05 a4 ultrasprt wheels on it, that would be great.
thanks in advance

 

They should fit they are both 5 x 112 patterns and I beleive they are both a stock 35mm offset though the a4 wheels may be a 40mm offset if thats the case they will still fit but they will be really close to the brake calipers. I put a set of 17" wheels with a 40mm offset on my 2.7t and they were very close I actually ground off the mold lines on the caliper to insure they would never flex a little and touch the caliper. But either way you should be fine.
