RedRobin, I’ve been an admirer of your car for a while now I too have purchased the V4 OSIR front lip from the USA which will be colour coded along with the side skirts and rear in a couple of weeks time (still deciding on either the R32 or ED30 rear bumper). I have brushed aluminium mirrors which I did myself which look great against the red. I will post some pictures when complete.
Did you have a problem lining up the OSIR front lip being as its in two parts?
