I have a "OEM TT" front bumper made by some aftermarket supplier I bought of E-bay. Jsut checked and they do not seem to be selling them anymore. The fit was very bad. Not sure if it was my front end or not, but I think it was due to their bumper just fitting poorly. Gaps between the headlight and bumper. Fender/bumper lines up poorly.
An OEM bumper with a new bottom lip sounds like the way to go.
