heres mine i just done..

its an s2 front mount so had to make my own brackets and mix match pipework but its on now. had to cut a big mouth cuz it comes out to far, other wise bumper wouldnt fit over it.

you need to cut the centre section of the front bib/panel like this, dont worry its not structural..



ive got a few pics i can pm you when i upload them. but generaly its very simple, gut the foam out the middle of bumper from fog light to fog light, attack bumper with angle grinder, then use a file to tidy up edges

excuse the splitter, i was trial fitting my unfinished carbon one.
