Hey guys - I am trying to figure out what to do here. I ordered the JG Mods Mtech pre lci front bumper and the shop is running into issues w/ the install.
I was told to also order adapter 51758040109, and fender liner ext.'s 51718040099 and 51718040100. Those parts fit onto the bumper w/o issue, but they cannot figure out how to attach those parts to the existing under-engine cover. Has anyone done the pre-lci front mtech bumper install? Can I re-use the existing under-engine cover, if so how does that attach to the adapter and fender liner extensions? Thanks.

Ok. So I think they have figured out what to do w/ the center adapter. But they are unsure of the fenderliners. Could that be because of my stock oil cooler?

I would like to know too

What did they do with the center adaptor? Im kind of in the same boat.

E90 must be different from E92. Mine worked fine without any extra parts.

I'm not entirely sure to be honest. I just told them "to make it work" - But I paid out the ass for it.

man, i hate it when some bodyshop just aint trying enough.


i did the same thing and got pre-lci rep bumper. shame issue of plastic liner being a bit too short to cover completely.
they were able to screw 2 corners each side new bumper to original plastic undercover but screwing the middle are is difficult cause org plastic is just not long enough but still possible with a little force and extra 5 mins of work.

Yeah I don't get why a damn body shop can't just figure the shit out. The body shop that did mine had to cut some stuff around the IC. I just told them to do whatever...you can't see in there anyway...and they did it..

So at the very end you actually managed to go without the extension (51758040109) and liners (51718040102)? I'm about to do the conversion as well

yes, it can work. you gonna need a bit longer screws maybe... i did, just to make it a bit easier due to unconventional linement being a bit off target.

Thanks fore the reply. Was your install also without the m sport fender liners though?

bad news man, Im not talking about Mtech but pre-lci M3 Rep with brake ducts. more aggressive look, Mtech is good too but front lines looks as if the bumper is making a happy face.

you need to cut up you wheel wells and plastic ribet them one, and ribet the center piece onto your undercarriage
