I'm not one to fire up the flame thrower but, in this case, I felt it needed to be done. I am truly amazed at the poor level of fit and finish in DTM Fiberwerks' product. I had read that they quality was not great but now I've seen first hand that they actually do put out some CRAP.
I will post pictures later because everyone should see what I am raving about and not just take my word for it. There should be proof behind any statement, especially a negative one, and I will provide it.
Here is my email to DTM from a few minutes ago, I'll post their response, if I get one:
I bought one of your e30 M3 evo III wings with CF flap at the end of November, 2011, and only got around to test fitting it this past weekend. The fit is HORRENDOUS. There is a twist built into the wing so the uprights don't sit flat on the deck. I'm talking about a 1/2" gap at the front end of one of the uprights. The holes for the mounting screws are about 1/2" off and why should I have to "notch" my factory deck? The overall dimension is also about 3/8" too narrow.
Your CF, however, looks very nice. But now you tell me that I may have to "notch" that as well? These are two pieces that were made at your location and you can't even get them to line up correctly?
Did I mention your wing is JUNK
