Please help with spacer question!

[VegasS5]

I have a set of dpe 20x10 wheels all around but I'm not happy with the rear wheels as they dont seem flush with fender.The question I have is what size spacer should I go with for rear wheels? I dont know the offsets because dpe wont give me that info.I'm wondering if a 15mm would be ok.Any suggestions or pics of spacers with a 20x10 wheel? Thanks

this will be hard to answer with out pics and an offset. theres a way to measure ur offset, u can search the forums and ull find a post, i dont remember were it is. its pretty easy. if u post pics of the wheels on the car maybe i can help u.

offset is the key

Ya without an offset or a side angled view of your fender we cant help you. You can measure your gap by placing a straight edge flush with your wheel then measure the distance between the edge and your fender

Effective et to run on a 10 inch wide rim to run flush on the A5/S5 should be around et 21/16 f/r +/- a few. What is the current et?
