I saw the one on ebay but I wanted four sensors for the oem rear valance. I can make the holes a little bigger. It's not like I'm drilling into my bumper or something like that.I saw that kit but decided that I wouldn't like the size of the sensors. It seemed to me that they were 28mm or something like that.
What I like about the Cobra is the sensors are only 20mm in diameter.
Maybe I'm wrong, so post some pictures of the sensors once you install them???
PS Here's another parking aid that looks very similar to the Cobra. It's less of course but should work ok.
Parking Aid on Ebay for $65.00 This kit only has two sensors where the Cobra has four.
