I have a 2006 a4 2.0t FWd.
Stock wheels and suspension,

will a set of s6 wheels 18x7.5 with offset of 20 fit?

Tryed searching cant find any posts with 20mm offsets
thanks!

 

Try tirerack.com. Input the year, make and model and see if that fits.

if you do end up changing the wheels yourself, you might find it difficult to take them off. I changed a slow leaking tire yesterday and I had to kick the tire a few times after I removed the lug nuts. The wheel siezes to the mount a little sometimes.

 

tried them, i see a few with an offset of about 35mm... but none with 20. im guessing they will stick our further than the fenders?
