Team,

I had the pleasure of testing my setup with Andrew yesterday against the TruSpeed S and DragonEye. He was not able to get a single punch through on my front or rear. I figured it was worth sharing the sensor locations for those of you wondering about good placement on a BMW. At first I was concerned my TX heads were too recessed but the setup proved to be incredibly effective.

Congrats! I need to pick up a set of those gloss black kindey grills, looks like the TX head fits perfectly.

How did you mount the heads? Are the brackets taped to the body/grill? Was there much adjustment required to get them straight and level, or did it work off the bat?

I wonder if you would be able to get away with 1RX/1TX in the rear?

I didn’t do the install but I know they used a combination of the mounts that came with the ALPs and 3M tape.

I should have done a TX in the rear, I think this would help my own issues of occasional punch throughs in the rear. Thanks for sharing.

I had the same setup on the rear of my F80 with just the two regular heads and it was a no PT set up! Im sure with the TX thats makes it just about impenetrable lol

Good to see those results on the front also, I had mine mounted lower and horizontal but the grill install looks easier and cleaner.

I have the same setup on my e60. This post makes me feel very reassured! My only concern is how perfectly aligned my rx heads are since I did my install myself. Setup looks amazing!

He probably doesn't know unless he takes a few pics up close since someone else did the install

Nice, congrats!

OP, I would peel off or black-out the warning sticker on the front driver's side head, just to keep from calling attention to those who don't need to be curious about what that might be...

It looks like they used the TX bracket and ran it behind the license plate. Probably attaching the bracket with double sided tape under the license plate.

Thank you so much for posting this! I'm in the process of planning the install on my M4, so this is a Really Big Help. I was concerned that the rear RX sensors would be too close to the TX head, but I guess it works out OK. Does the TX head get in the way of using the trunk release?

I can see the RX sensor brackets in the rear, but I don't see them in the front. Did they use them in the front, or did they just use tape? I was going to just use Sugru, but if there's a good mounting place for the brackets I'd prefer to use them.

Are the rear sensors protruding out a bit, or are they fully recessed? I don't know if the rear on the 440 is different than the M4, but mine has a little arc to it so I'd either have to have them partially sticking out, or somewhat recessed. My OCD wants to recess them, but I know performance could suffer - if yours are a little recessed and you're getting this kind of performance, I'd be a happy guy.

Thanks again for posting!

Glad I could help. They used the mounting brackets in the rear for sure. The TX is secured behind the license plate. All of the front sensors are just tape. It’s a lease so I was adamant about no holes so they actually removed the heads to runs the wires and then crimped them back on. Kind of funny because they then cut a hole in my dash for the control panel lol. They swore they can fix it and I trust them.

Attached is a picture so you can see the trunk handle. It does get in the way slightly but I don’t have an issue with it. Use two fingers instead of my whole hand. Also, I mostly use the key or kick my foot under the back to open the trunk.

None of my sensors are protruding. My RX sensors are flush both front and rear. My TX are slightly recessed both front and rear. I was concerned with the TX being slightly recessed but had awesome results when testing with Andrew. Was able to get JTG with zero punch throughs. He still recommends moving them out but I go back and fourth because I like the way it looks.

My trunk has the arc as well but the M4 has a spoiler that does make it more defined aka stick out more. You need to find a balance. You bought a beautiful car so even if you only get jam to 50-100 feet is it worth having ugly sensors protruding out. In my opinion hell no.

As always get the setup tested but I think with two RX and a TX that are leveled properly you will be sufficiently protected.

Interesting how you mounted it, I don't have a lot of space for a TX sensor but I guess I could put it on one of the rear license plate lights lol
