The PSM Dynamics does not require to remove the portion of the diffuser where the sensors are in, just slips over the lower part. I painted my OEM top portion and PSM bottom gloss black and all sensors work as before and trunk works as before.
My sedan with the Lufstrom diffuser left parktronic and the back up sensors useless, not to mention they would set off and tried adjusting and reglueing(bummed no tabs!) Ended up grabbing a PSM since i have one long *** driveway with a 90 degree turn backwards into my garage each night

Thanks for the input from another sedan owner. I think I've decided that for now for an aesthetic change that isn't that drastic, the total cost (part + labor) + risk of losing functions + risk of panels/gaps not lining up as well on the reinstall of bumper and diffuser, makes it not worth going forward with it for me, personally. The car is still very new to me so perhaps sometime down the line I'll be itching to change it up.

no rush needed....just in case you do decide one day ... my PSM sedan diffuser does not require to remove anything (bumper, old diffuser)... I just removed the small trim pieces and use the small grooves where they used to be to seat the top portion of the diffuser, It then gets attached to your bumper left and right with 3-4 screws each side underneath. The diffuser ends at the wheel well.
uhm, shall I send a video showing it? Works 100% all the time, only way I open and close my trunk...with the PSM installed. Funny you doubt what I am experiencing every day.
Ok now i'm jealous. How the hell does that sensor not get blocked by the psm rear diffuser? I'm going to try to kick it in every spot today.

to be honest, I was bit surprised too but works like a charm. I kick right in the center. what I did find is that you just need to kick swift...too slow and it will not work. throw that leg ;-)
I been thinking about this diffuser but its so much more than the other diffuers lol. Was yours carbon fiber?
Nope, I ordered all FRP and have it all painted gloss black. I also painted the remaining OEM top portion of the diffuser gloss black to match it all. My entire car them is white and gloss black on all exterior parts (and black-on-black and carbon fiber interior including engine bay).

FRP + paint is the same as cost of CF though.
So that's interesting that yours isn't CF and seems to be one of the few in this thread with working kick function. When I called my local shop for an install quote and was talking through my concerns, he mentioned that carbon fiber can definitely affect sensor functionality. Something about the material specifically can cause sensor malfunctions. He said he went down this rabbit hole when installing a CF diffuser on his M3 Competition and lost the kick function.
Just spent some time on bimmerpost and there is a ton of discussion on this. Boils down to carbon fiber being conductive. This acts as an RF shield preventing the kick sensor from "seeing" your foot.

certainly possible but when you look up dielectric constant of carbon fiber laid in epoxy it does not show that it has a much higher dielectric constant than plastics alone. But certainly a possibility. The kick sensor is likely a proximity sensor based on the change in reflection of the electromagnetic waves caused by your foot. A dielectric shield in between would certainly make it stop sensing any change. FRP it is is 😃
I have a sedan with the ModeCarbon , all sensors work fine.
As others stated it does not come with specific hardware, so take your time. The parking sensors need a little love when re-mounting them but if you or your installer doesnt RUSH the job, all should be fine.
I
done mine myself, had to do quite abit of cutting and move some cables around but all works fine. My only dilema is the 2 sensors on the diffuser keep going off as they are more angled to the floor. But like I said I fitted this myself and drilled the holes and I’m not a pro. But will get one of my pals in the garage to look at it and hopefully readjust them.

Looks like it came out just fine; nice job. As for the parking sensors, the area they mount to on all the aftermarket carbon fiber diffusers just seem to be on a section that's curved, making them point more downward than on the OEM diffuser. If you're able to figure out a way to mount out so they're pointing more horizontally, let us know.
