hello all I like to have opinion on this front spoiler it is for E31 and I modify for my E9 what you guys think, I don't like E9 front spoiler it is very flat and nothing to it but this one its got character and look like a front spoiler I work all day today and make it fit, E31 front is little wide I got this for my E31 V12 but I change my mined to install it original bumper is very nice then I start modifying for E9 now after installing spoiler should bumper remain installed or without bumper I saw lots of people have spoiler but no bumper installed. please check the pix
