I used Macht schnell 5mm spacers in the front, but they didnt give enough lip for the 135 wheels to sit on. I had vibration issues with those spacers. I went to turner 12mm spacers now and it fits great. Looks weird cause the rear has no spacers but, this is for daily driving only anyways.
I tried the 12mm and 10mm spacers on the rear with the 18x8.5 +50 and I had rubbing on bumps but I am pretty low with factory size 255/35/18.
