MPorium M3 Aluminum Undertray - A must for M3s!
I was about to replace the felt undertray of my track E90 M3. OEM options were over $400 and wouldn't last more than a year. I discovered MPorium M3 Aluminum Undertray and couldn't be happier with the build quality and fitment.
deansbimmer make these, cool guy. Just be patient as they could take a couple weeks to make. OEM vs Mporium Aluminum Undertray. OEM tray was cracked and one of the weather strips to the oil cooler was gone, causing a rise in oil temp. Screws and Drill Bits included Installed photo. I could've added more screws on the side, but these were enough and sturdy. I highly recommend this mod for the same as OEM replacement. This does a better job at protecting the oil cooler, less likely to rub against driveway curbs, and will last the life of the vehicle.

On the OEM setup, there is a felt box on each end that sits lower than the main tray. I don't see that on the MPorium version. What is the purpose of that felt box? aerodynamics?

I can think of a few reasons why the OEM is like that: (1) The OEM central piece is held by these stupid steel cable with nuts, it's super annoying. The side pieces hang down to match the center piece for easy access to the hanging bolts and nuts. Mporium don't require these hanging cables, which is a huge relief. (2) The OEM hangs down to be a "feeler" component, warning you not to drive further if you're close to a tall obstacle. However, the OEM cracks so easily so that is useless. (3) OEM piece is designed to be assembled quicker, no drilling or eyeballing to fit.

The difference is OEM gets destroyed so easily, when the felt pieces crack or punctured the oil cooling function deteriorates. These will not crack or get punctured. I'm not doubting that OEM felt's hump creates more negative pressure which pulls even more air out, but when you hit a single debris on the highway the felt cracks or punctures which throw that nice idea out the window. So far, no one reported oil cooling issues with these. In fact, I'm sure my oil temp will lower as my OEM felt was cracked and one the weather strips were missing causing air leakage.

Side bonus is we can remove the undertray without removing the wheels. Just remove all bottom screws and out it goes thanks to the end L brackets. So I just leave L brackets attached to the fender lining when removing.

Also, maybe I'm crazy but the I can hear more engine sound. Maybe the felt insulates the sound and aluminum amplified it. Hope others with it can chime in to make sure I'm not imagining it.

It wouldn't surprise me--I think the felt is part of noise abatement for European regs. Or maybe I just dreamed that.

Which is the steering line in this pic that needs bending? This is one of those installs that you hardly see, but feel good about doing 👍🏻
