Neil,
Are you running Bilstein B4s and Eibach Pro springs?
Your car looks nice on those 18s at that ride height. It's not silly low and would imagine it's still comfortable.
Yes I'm running B4's and Eibachs and I can't say I have really noticed any difference in ride quality since going from the 17" RS6's to the 18" CH's, I thought I would have but my ass
must be is that fat it isn't registering the difference
And sorry guy's but the 6's are being refurbed and kept for winter rims with some tyres that actually grip in snow unlike the Eagle F1's that are on them currently
Neil
