Hi there folks... Recent new owner of a C7 Saloon, I have the Black Edition (2WD) so has the 20" Rotors which I like... But was hoping to to just get a slighty smaller tyre - arch gap and hear the Eibach are best for keeping comfort. I only want a small change... BUT will they go lower than already Sline suspension? Some pics if anyone knows of Pro-Kits on 20" wheels would be great. Thanks in advance.
