Hi all. Sorry, I know we have been over this many times but I am still a little concerned. I am looking to put a set of Borbet 18inch x8.5's on my 03 stock a4. The wheel I want has an offset of 30mm. My understanding is that would put them out more. Question is, on stock suspension, is that a problem? Any thoughts? Thanks in advance. - Chris

 

also, will the bigger tire throw off the speedo?

 

Are y'all so tired of this you can't help? C'mon!

 

Go to the offset calculator where you can compare down to the millimeter the difference in inner and outer clearance between your existing wheels and the new ones. (If, for example, your stock wheels are 7.0 wide with a 35mm offset, the new ones would stick out an additional 24 millimeters). You can measure the difference against your stock wheels and see if the new ones will fit.
