Used to fit these at work, all you do is remove your bumper and its a roll of metalic strip that sticks onto the inside of your bumper. There a good idea for being invisible and not too bad, seem'd to work ok when we used to fit them at work, we now use the drilled sensors, x vision kit, but i would prefer the invisible ones.
 
This does look good. I think I saw this on an older thread but I cant seem to bring it up on search... are all the wires that you's need to connect to in the cluster by the left wheel arch? Just trying to figure out where to run the wiring in my head.
 
Someone on here does indeed have this fit as there was a thread a while ago that I can't find, suppose I could trawl my old posts but can't be arsed right now.

They said it was simple and reliable.
