According to the site its a MTechnik bumper and lumma lip.... Doesn't look like a lumma lip.

Heres the link to pictures. Mtechnik

 

I've seen that blog and wondered the same thing. I don't think its a Lumma lip either but I really like it! It's different and really clean. Probably a JDM brand but not 3D Design either. Hopefully someone knows, but to think about it. This looks very similar to the RD Sport M-Tech lip but with out the the gap/hole in the middle of the lip.

 

I think it's a RD sport lip. Here is the original post https://5series.net/forums/topic/102950-jlevi-sw-rd-sport-aerodynamic-parts-for-the-e60m5/

 

I was looking at that too. But yeah no gap. Looks like a cross between RD and Hamann. Hamann lip

 

Now looking at the sedan at the bottom of the link has a similar but different lip as well. No gap but larger than the RDsport one.

 

Found some more pictures of the sedan lip on japan yahoo. Lip Too bad theres no info about it.

 

im really confused about the rd lip... i dont see where the bumper ends and the lip starts LOL

 

This one looks like the RD Sport lip or VERY similar. It might be the color that is throwing it off but I like the one in white better. Perfect lip to throw a splitter on. Yeah to bad there's no more info on it but there's also the RDS lip if you want something very similar to it. $1,000 though

yeah they did a really good job of making it look like its actually the bumper unless they actually molded the lip onto the bumper
