MPorium M3 Aluminum Undertray - A must for M3s!

[slowdown_dan]

I appreciate the visual. Thanks! Next question, would you be willing to share the design of the prototype air ducts you were working on for the tray (if you've decided to shelve that project, totally understand if not) or sell me a set of them on a prototype basis?

They required cutting of the bumper and we only made one set bespoke for a customer. It's in our plans but not available yet.

If/when you want to make another set, put me at the top of the list!

Material wise someone can reproduce this for under 100 dollars. The simular produce purchased for my z was 189 dollars shipped, water jet cut and perfect fitment. the term M tax is real.

Turner's Undertray is $585 and has less ground clearance

Why does Zolgensma drug cost $2.1M per patient? Why do parts for an M car cost more than a non-M car? Because R&D / capital investment are sunk costs and your potential market is small. So it requires a larger dollar sale price to break-even and make a profit.

The tuner motor sport tray is a multipe pc tray that attached to the frame These are not even comparable. I compared the tray made by z speed factory as it actually shares the same concept of the deans tray Flat sheet metal cut out to use oil cooler ducting and bolt up to splash shields with there even being stamped pressed.

Lololol, Anyone who's been on the forum since day one knows this is blatantly false.


The humps are there for a reason...aero. They help direct and smoothen air flow around the tires.


Just wanted to set the record straight.

The whole point of me buying this tray is avoid the multiple piece tray, with hump that bolts to the frame which is a pain to remove everytime. The one I have is super sturdy and extremely easy to remove.

I'm not sure what your point is, unless you can convince another company to make trays for the E9x M3 for the same price as the Z market. There's just simply aren't enough people with an e9x M3 that desire a tray enough for a company to spend time R&D and manufacture.

Sure you can make this yourself and save $50, but by the time you source the metal, work with a machine shop, source the screws, and high temp rubber trim... How much is your time actually worth?

What Mporium solves are 2 things: Offer a more durable tray for OEM's fragile felt tray pricing and offer more ground clearance compared to OEM. Another company that makes a similar tray is Mumbray Motorsport at 320 EU + massive shipping fee from the UK.

The OEM felt is $400 which sits too low and doesn't last more than 2yrs.

If the OEM felt tray lasts more than 1 speed bump or a rock hitting it at 80mph, then you "MIGHT" be correct. Otherwise, a flappy cracked OEM felt tray isn't doing jack for your car's aerodynamic.

See @offaxis OEM tray. Doesn't look so aerodynamic to me. Mine was cracked and flappy, so no thanks to felt.

That was fast.

Just to be clear though, you don't have to spend $400 on a BMW felt tray, if you only break one of the three parts.
The center trays can be had for $240, with a lifetime warranty from FCP.

Or $185 from Turner.

I must be missing something. Is that huge gap on each side expected? I didn't push it in all the way so I can get a better picture of the issue.

Pretty sure I checked the box for "remedial DIY instructions" but got the regular instructions instead.

Yes

Yes it is normal to have an air gap on both sides. A flat replacement panel cannot follow all of the contours of these bumpers. The openings allow additional air to be split off for brake and exhaust cooling, and creates additional scavenging for air flowing through the main radiator.

I’ve had this tray on my car for 2 years and it’s fantastic. Would recommend for all M3’s.

[MAE90M3]

I just ordered this. Am I correct in assuming that I need to source my own hardware to attached it to the car?

No, it comes with new screws/bolts and a drill bit. It doesn't come with the cables (51758044393), but those aren't *necessary* for installation.

Second post that says this. If it is for Aero then why is the GTS spoiler/tray flat just like this? I will stick with the flat MPorium tray.

[DILL_M3_CAN]

might need one of these in the near future, my oem one is trashed.

Im not too happy with my tray but I guess it works?? Mine and a few others seem to hit an oil line on the passenger side. I resorted to wrapping the contact point. I'm not sure if this is a specific issue with our cars or by design. Also couldn't get any of the front bottom bumper screw that hold the oem tray on as this tray is very rigid and seemed no.way to attach without bending bumper severely. Just my honest feedback.

Here is a post from our main thread which addresses the oil pipe:
