Folks, I'm doing an Msport conversion on my 2011 E90. I have already done the rear bumper and side skirts. I have the front bumper, but it isn't simply the case of slapping it on. I need the below. If anyone can help, that'll be great.

Front Left Brake Air Duct 51747891379
Front Right Brake Air Duct 51747891380
Adapter Under Hood Shield 51117892935
Deflector Lip, Left 51717892697
Deflector Lip, Right 51717892697
Cover, Bottom Left 51717892801
Cover, Bottom Right 51717892802
Adapter 511758040109

Real OEM will help to locate the parts using those numbers, instead of uploading pictures.

I'll have a look at the arch liners I've got later. Don't recall seeing brake air ducts on the M Sports I've worked on or owned.

They look like this. They are shaped differently to the standard ones.

These are all the parts I need for a proper conversion.

I think I've duplicated some of the pics.

I don't think you're aiming for a run of the mill conversion. I have checked my car and the one I recently broke and neither have brake ducts. The arch liners I have are closed completely

Is yours a 320d LCI? These were the parts that were showing when I went here:-

https://www.e90post.com/forums/showthread.php?t=804340

I'm not sure if it's because the US spec cars have the ducts because of different brake setups? I'll need to check the fenders of my car to see if there are any ducts. What about the other parts? I think the fender lining is different anyway because of the screw holes? The SE has 3 and the Msport has 2 along the sides where it meets the fender lining? Also, did you notice that there were some extra parts joining onto the plastic shielding under the car?

[sfarisminhas]

I have just checked the fenders and they look to be sealed, other than the flaps to get to the bulbs. A lot of the stuff seems to be mixed information and from the US. Leaving aside the brake ducts, is everything else on the list on any of the cars that you have broken?

[Andystobbs]

The part numbers won't marry up because you are taking yours from a retrofit kit. I have 5171 7903910 which is a cowl and 5171 7903909 which is a cowl.
And both the matching parts that go to the rear of the front arches.
5175 7 128 503 which is a radiator lower trim, that may not be M sport specific.

My car does have the lips underneath but they seem to be missing from the breaker

Edit, tell a lie, I do have the underneath lips

Okay, so the first two numbers you have given me are for the front wheel arches? It looks as though they don't have openings for brake ducts.

Do the lips fit under the bumper itself? So we are talking about 51717892697/8?

What about the adapters, which are 51117892935 and 51175804019?

Yours is a 320d LCI if I'm not mistaken?

The info seems to be conflicting and/or different. Maybe because of US spec cars.

What hardware is used to put the lips on? Is it some blind rivets?

[sfarisminhas]

What about these two?

[Andystobbs]

My car is indeed a 320d the breaker was a 330d both M sport LCI E91.

The adaptor is the piece I recently ordered from bmw on their advice that it is required but having now looked at it it doesn't seem suitable at all. Both undertrays are the same but I can't find a part number on them. No way that adaptor will mount to it.

The thin strip I've never seen either but does look like it could be mounted on the tray. Both my trays have 3 ripped out fixing points.

The lips look to be on speed clips and screws - same as the undertray

The thin strip I've never seen either but does look like it could be mounted on the tray. Both my trays have 3 ripped out fixing points.

Okay, the adapter you ordered, is it the one that is labelled number 13 in the attached picture? It is held in by number 23, which are blind plastic rivets. According to the hardware key, you order 5 of those rivets. They hold on that adapter (13) to the bottom of the bumper by the looks of it. They also hold those deflector lip (10), this would explain why I have blind rivets in various positions on the bumper.

I assume the thin strip you are talking about is number 11 in the second picture. I think that attaches to the main tray itself.

[sfarisminhas]

These are the ones I am talking about. They are marked in these links.

51758040109 is the adapter I ordered from BMW. Your second picture. It looks hopelessly unsuitable at first impressions.

The first picture looks like it'd be useful.

That part you ordered is basically extends the tray so that the bumper holes line up.

[sfarisminhas]

Andy, can you tell me if the lip is mounted to the bottom of the bumper or does it sit in between the bumper and the tray?

[Andystobbs]

Now you're asking, on the bottom of the bumper I think.


You suggested that the adapter extends the tray to meet the bumper yet there is no where on the tray that matches the shape of the radiused side of the adapter. The straight side looks right for the bumper but the undertray is totally plain except for the three missing mounts I mentioned earlier, which are less than 3" from the front edge.

[Andystobbs]

My undertray is identical to 51718047423

Ps they are cheaper direct from BMW than on ebay. By £100
