I thought about keeping the front 15mm and getting a 10mm for the rears but i wasnt sure if it would affect the car
Exactly!! I do not know if making the front axle wider in proportion than the rear will affect, better to get an all-around spacer to keep the same proportions.

There's a couple of metal ones for around $40/pair total shipped. They were four or five down from the top.

Replace the 15 with the size of your choice. You'll probably need longer lug bolts too.

edit: while checking my work, I noticed that there are spacers and longer bolts further down.

Thank you I found them, the ones with bolts are around 100 dlls, I searched for Audi 17 spacer 15mm to narrow it down, because the other search gave me some other models, but if the spacer is 15mm, 66.5 and 14x1.5 should be exactly the same.

Not sure if this is correct. steelblue7 has hartmanns (offset 40 if I remember correctly from another thread). 15mm all around puts it to 25?

The stock 20's have an offset 37 (again from reading in another thread) so that's why the 12mm would do to bring it to 25 as well? Or this is completely inaccurate.

Sorry guys, I'm not so sure how it all works hence asking you guys with more knowledge.

I just meant that making the front axle wider than the rear (in proportion) just because you can fit a bigger spacer might not be good for the car, this is just my common sense talking I have none experience about spacers.

Here's a good site for comparing tire sizes, offsets, clearance, revolutions per mile, etc.

So I went to my shop and got things measured. With the stock 20's that I'm on, the most would be 12mm in the front and 15mm in the back.

I went ahead and ordered the Eibach, spacers and lugs. Now the worst part, the wait before installation.

Thanks again for the help and input! Will update with pics whenever that will be.

You do not have the stocks 20s do you?, what are those in the picture? you didnt see the front gap bigger than the rear's???, also did you ask the shop if modifying one axle more than the other one has any adverse effect??

Yup, mine are the stock 20's that came with the car. I think the Cananda S-line and US S-line gets different type of wheels?

When he measured, 15mm in the front would have the tires sticking out pass the fenders. I didn't get to ask him regarding the axle question, as I wasn't too concerned with that. If it did have adverse effects, he would of told me as he has done quite a number of S5's and other Euro cars.
