Just picked up my audi from the mechanic. I wanted a more aggressive look to my Audi A6, so I asked my mechanic to get me some wheels spacers. He got me 10 mm all around, but I didn't get the look I wanted. He said that he was not able to get 12 mm, and there were not available. I looked up the options for spacers on my 20" wheels. My mechanic said that 15 mm were not recommended, but what about 12.5 mm spacers. 🤔 Any comments.
