I had my mtech front bumper installed a couple months ago. I wasnt very pleased with the fitment (it's a replica mtech, not oem) as there are gaps everywhere. The worst gap is under the headlights, where i can slip my pinky in there i did not buy the necessary hardware such as shock absorber, radiator shroud, support, brake duct, etc because the dealerships here did not have those parts in stock. The bodyshop removed the foam shock absorber altogether. i feel like i'm still missing some parts to make the bumper sit right. I have a list of part numbers (the car is a 2009 530i with n52 engine, equivalent of 528i in the states):

Front Brake Air Ducts 51117896587 and 51117896588
Side Panel Support 511117033705 and 51117033706
Shock Absorbers 51117896591 and 51117896592
Adapters 51117896611 (2 pieces)
Supporting Ledge 51117063835
Adapter Strip 51118032081
Damping lip 51117897214

I cant seem to find the part number for the radiator shrouds and top and bottom air ducts though (yes I searched). I searched realoem and came up with these part numbers but Im not sure theyre the right ones:

Air duct front left 51 71 8 036 575
Air duct front right 51 71 8 036 576
Air duct front bottom 51 71 7 897 174
Air duct bottom 51 71 7 905 332

Are those the correct part numbers? Am i missing any necessary part?

Thanks

For the front bumper I'm not sure you need all of those parts. The frontal crash pad is needed or it should be trimmed to eliminate the interference. Your car is LCI. So the wing clips on the sides will not engage properly without additional trimming and modifying of the pad. These bumpers were setup for pre lci but will work just fine on lci if this done. Otherwise you will have these gaps. Sounds like your body shop didn't want to spend much time tweaking the fitment for you. It's not hard at all to do it yourself and then you get to learn and understand your car better. I can post and send you my information on this if this is something you want to try. I'm out of town at the moment but can send tonight if you are interested.

I found it so take a look at page 7 and this will give you an idea of what needs to happen in order for the wing clips to engage. I don't think this is required if you have pre-lci. Once you remove your front bumper you will see the black clip that is held in with a few screws. the best way is to just remove it and match it up to the bumper wing and trim accordingly.

Gotcha. Thanks a lot for the pdf. It was really helpful. Yes I'm thinking of removing and reinstalling the bumper myself. So just to clarify, i dont need all those other parts other than the crash pad and wing supports? I will go ahead and order those parts. I wont be needing the radiator (air duct) guides? The bodyshop didnt spend much time tweaking the fitment because they didnt have all the necessary parts to make the bumper sit perfectly.

Thanks again
