Let me how the fit and finish is. Do you have to remove your "dove tail" spoiler that comes on the car?I too had the same thoughts for my GT350, if you buy one from Ford they are $1900+.
There are a few options on Ebay from 3rd party manufacturers, be careful, Most if not all of these are coming out of China.
I bought and received one of these R spoilers this week, it is a nice part with good quality. It comes primed black, you need to paint it.

Let us know what you find when you install it. Maybe some pics?The R spoiler I have is mounted by 4 bolts on each side. It fits to the back-side boundaries of the trunk lid, so I expect it will cover some, if not all of the Tech spoiler holes. If there are any exposed holes in the center section, I will deal with that by installing a temporary plug or a permanent change.
The R has a bigger splitter up front to complement the increased downforce of the wing. So it would be wise to change out splitters as well.it's really going to throw off the aerodynamics....i saw a video on an R and they said if you want to order one, they run around $12,000 from Ford....sounds high, but I'm glad...i don't want anybody that doesn't have an R to buy parts and install them on a normal mustang....pisses me off to see a hood and nose from a GT500 on a POS 4 cyl mustang
I myself will need to get this car on the track and try it at high speed to see if there is any negative effect on the front end handling.The R has a bigger splitter up front to complement the increased downforce of the wing. So it would be wise to change out splitters as well.
I made a rear brake light housing from a nylon block and mounted an LED light bar using the 3 holes for mounting and wire access.Looks Good! What are your plans for the 3 holes in the decklid?
