I think Jon is looking for something "too" custom. The BW bumper and any other MFG's bumper are replicas of the RUF part! Look at the pictures of the Yellowbird, and you'll see why they look like they do. My guess is that they wanted to give the appearance that the parts are "bumper caps." That is, that there is a bumper under there...so as to not offend an astute officer of the law...or maybe not.
If you want a smooth look get a C2 front bumper. The CTR bumpers are "CTR" bumpers. You wouldn't as for an IROC or RSR bumper, then ask that they make it look like a C2 bumper would you?
Sorry if that sounds like I'm menstrating, but I'm not a politically correct player...don't even ask me to play office politics...
Really, Brad is a very nice guy and has done an aweful lot for the group, and he made the cooler duct bumpers after a few of us expressed interest in them. BUT(!) it too is a replica of the authentic RUF bumper. Making a mold to smooth out the deck and features of the CTR bumper is probably not going to fly, since there is no historical significance to such a part, and Brad would likely only sell a couple. Not a smart business decision. There is another firm that makes hybrid f-glass bumper covers..I think the are Fiberwerks or something like that.
Go to page 1 of this thread and compare the real RUf part tot he replicas.....
