I didnt have any sensors so i had to drill holes in the bumper to fit these.Did you need to drill new holes or do they fit into the ones that are mounded into the bumper as standard?
Good stuff mate.
These were on my CTS when i bought it.
They were grey right enough but got them painted when i colour-coded the bodykit.
Couldnt live without them now.
Kinda dodgy when parking my wife`s car though and waiting for the beep beep.
