Just fnished it up...Came out dam near perfect. I read the post by the guy here on Audiworld b4 doing this and he said his only problem was getting it straight...so at first glance I could see where he is coming from but once I got underneath the car I saw the solution immediatly. The bumber itself has a curve along the backside of it from underneath so all I did was figure out roughly where I wanted to mount it, measured from the curve to the rubber piece and make a stencil. Place the stencil at the curve of the bumper and every 3-4 inches make a mark with a wet/dry marker. Find the middle of the rubber piece and the approximate middle of the car and set your first screw there and just follow the line you made with the stencil around. Once I got to the curve just before the fender I had to think a bit how I wanted it to look. Initially I wanted it to look like London-TT's Cupra R spoiler but quickly realized it would be tough to curve the rubber piece w/o making dimples so I just stoped it there with about a 30 degree cut starting at the little ridge piece there and going toward the middle of the car. Anyway like I said it came out almost perfect, it needs a bit of reinforcing IMO, not sure just screws and 3m will hold it on at high speeds so tomorrow I will take and put a small bead of silicone underneath just for reinforcing purposes. I did take pictures from underneath showing the lines I made with the stencil and how I made the cuts and the finished product, cant find the USB cord and its midnight so pics to come. Easy diy takes 30-45 minutes and cost is 15 dollars....Two last thoughts 1. don't space the screws less than 3-4 inches apart, will make dimples noticable from the front (if this happens remove screw and carry on, removal of screw fixes it. 2. I think the Mini thread said 3m may work alone, it will not, the rubber piece is too heavy. IMO 3m is good to help hold it up while you are setting it in place but screws and a small bead of silicone under the piece and a night to cure would be best.

 

Nice descriptive post though ;-)

 

Oh... just read that you'll be posting them later :->

So you found a rubber piece at HD? Mine was foam rubber. Too light weight...
