I am thinking of getting some spacers- I have A4 RS6 style wheels - S-line ones from 2005. I want to push them out to the arches slightly to fill the arches, but don't want to get any rubbing. I am running 235 tyres.
I have searched but wanted to know if anyone else has the same set up - i will probably lower a tad at some point too. Will I get away with 20mm or stick to 15mm?
Also, do i need longer bolts to acheive this?
