you are right, but this is what it worries me how to mount them between the grills so the are align you see the gaps, and is not like you can just put it flat using a double side 3M tape

I have a wielder friend that may be able to fabricate some custom brackets if calvino's testing of the horizontal orientation results are poor.

I was thinking of a combination of 3M Dual Lock or double sided tape and a bracket (as an anti-theft measure). Although the problem I see is that if I use both, then the grill will no longer snap out as the tape to the head to the bracket would fasten it into place.

So I think I will have to just do one or the other.

As for tape I was thinking of spreading the slats apart slightly, pushing the head with the both sticky parts in place but with non-sticky spreaders at the top and bottom so the heads will slide between the slats but the non-sticky parts would have enough frictional hold to allow me to align the heads. Then I plan to un-spring the slats enough that the sticky parts make contact and then hopefully slide the non-sticky spreaders out without misaligning the heads.

Sounds complicated and not-workable? It is - which is why I am seeking advice.

Brackets would be better.

+1 on the brackets. I'm gonna wait for some testing of vertical vs horizontal then i'll probably follow the DIY for whichever is better.. I've got an E92 so it may be a bit different

I received mine. I'm looking forward to the head placement testing, Calvino.

well guys Cliff is on Vacations but I think the horizontal mount is not effective.

today I had to parallel park I was afraid of getting to close to the other car so I turn on and off the LI so enable the parking sensor and I notice that I was not detecting anything I when down the car and I put my hand in front and it detected but a couple of feet away and it did not detect it.

the grill is causing hurting the performance of the device I when to my house and try it with my garage door closed, I try with the grills and I was unable to get a parking noise I remove the grills and it works.

the grills are really hurting the device performance.

we need to figure out how to mount the head vertically on the grills.

I think is a good idea if you start asking your friend

X-post:

I finally found some time to at least take my kidney grill out and look. A vertical install is not going to be easy, but then I don't see how a horizontal one is easy either.

BTW: the best way to remove the grill is in this thread:

http://www.e90post.com/forums/showth...ighlight=grill
You will need a Torx T-30 screwdriver to remove the four screws. Then pull the panel that hold the grills forward and slide your hand in behind and push/pull each clip toward the center of the grill to release the catch.

The outer most grill slot on an E92 is too small. The next one is blocked at the top by a clip that holds the grill in place. So you have to use the third opening from the outer edge.

I was going to use tape. I don't think that will work because the slats are curved and there will not be enough slat surface in contact with the head, plus I don't see how to easily slide the head in and get it level.

So I am going to try using brackets.

One of the supplied L-brackets will work at the top edge of the grill. The top edge of the grill is flat and reasonably parallel with the plane of the road. You can remove the chrome trim and make a hole in that top edge and bolt one of the L-brackets through it and fasten it to the tab on the head.

Finding another fastening point lower down to ensure the head does not move over time or at high speed is more difficult. The bottom edge of the grill is curved, so a supplied L-bracket will not work.

You might be able to fashion an u-shaped bracket and attach it to the grill slats and then attach the head to the bottom of the u. But you would have to attach the sides of the u-bracket to the grill slats and I am reluctant to drill into the slats (you would have to drill at an agnle).

I am trying to fashion a bracket that will fashion to the curved bottom edge of the grill.

I want to use aluminum. Stainless steel is not easy to work. Galvanized steel will rust over time. The problem is finding aluminum flat bar in a reasonable thickness. The bottom bracket will need to be bent at angles to make a z-shaped bracket in order to position the head perpendicular to the road surface.

This is going to be a PITA to level. There is no room to get at the back of the grill with the grill in place. So, the grill will need to be put back in place to test the alignment, then removed to make any adjustments, and then the process repeated.

You can use needle nosed vise grips to squeeze the slats together to hold the head temporarily in place to mark a line to which to align the edge of the head.

Anyone finished up the installation and can report on the effectiveness of the unit? Mine is still sitting in my garage. I haven't had a chance to install it yet. Tx.

Ha ha....i'm with you. Mines been sitting in my office for a long time. I've been traveling a lot, so just haven't had time. I don't think I'm going to install it myself anyways....I just don't think I can do it near as good as a pro.
