They were on the car when i bought it from the previous owner, so no idea. I have inspected them though and they are in very good condition, it also just passed its MOT and im sure if there was an issue it would have been flagged then.
This is how mine looks (it doesnt look bad, just wish it was a tad lower):
not sure if its the camera or just the way the wheels are, but they are 18" rims right?
