i have them (slightly customized cf version) on my bomex DC5. they look great, really finish off the look of bomex kit, etc. visibility is only slightly reduced, you have to point the passenger's side to almost the extreme outermost angle to get safe visibility. i say they're worth it, way moreso than TYC mirrors or such. i'll try to post pics of the view if you all want when i get my car back...again.
now if I could only get my hands on a set of carbon ganador mirrors :drool:
