Go to any dealer and order the rear Z06 mudguards. But u have to cut two of the tabs to fit on a regular C6.. Easy install and they look great! You need high bonding two sided tape to attach them (3m 4210) ...which I have if u need some!
GM just came out with the Z06 style mudguards (front and rear) for the C6. Best is to buy from a US dealer like Fitchner in Montana (I think they're $100 or so for the set of 4)............if you're interested in ONLY the rears I'd be interested in getting the fronts......
I had heard about some changes going on there. Let me look into it and get back to you.Silversurfer, Checked out the website for the Mudguards, however seems to be locked out or something. Any chance you can give an idea ref ordering. Did you have to log in to there website as i don't seem to be able to figure it out and or even log in.
