Hi all, been a while since last post but here goes.... I'm soon to lower my S6 V10 on KW coils but need to get the right wheels to avoid rubbing etc. Has anyone gone down the 20" route on their C6 and lowered it? What wheel / tyre fitment do you have and have there been any issues? I need to know exact specs on wheels and tyres to ensure I don't order a lemon! Thanks in advance.
