just bought my stagea last week, it had 17x8" all around (RS4 manual so no auto rear stick out) that sat way too far in and were missing centre caps, i just got some new speedy cobolts in black and in 18x8" with a et+35 offset after 4 days. soooo much better. i found out once i pulled the old rims off that they were fouling the rear struts and were 17x8 et+42 which is WAY too high. id say +35 is the highest offset i would run on a stagea. i could tuck these new rims very easily too. my guess it for a 8 - 8.5" wide rim et+28 would be perfectly flush with the body of the car. was guna go bigger but have a baby on the way so i want some comfort still.
