LTMW (formerly LTBMW) has done many custom front bumpers and can probably make what you want. He uses OEM bumpers and somehow "welds" them together. There are NO SEAMS and it's OEM material.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
