Any updates on shipping/stock? I ordered it last week hoping to get it by xmas and the shipping info was updated and was set to be delivered yesterday, but I checked again today and it's just pending and haven't shipped yet?
These are in stock. All orders have been shipped or have been packed and are pending pickup. Fedex is here every other day. We are closed weekends. If you need more detail, please email the shop directly with your name or order number as we can't cross reference your order with a screen name. Thanks!
Ok. I guess mine is pending pickup then.

Fedex is slow as hell here in CA so I'm assuming it'll arrive after xmas since there is only today and 2 days after until xmas.
Do you still make this?

We do. They are out of stock currently. We're waiting for production of the next batch to be completed.
Whats the wait time until completion?

Product is A+. Incredibly well designed and built.

The "bad" only comes with installation IF you have a larger oil cooler or intercooler, like me have the AA sc kit. I have a much larger intercooler and piping down there which gives you less than zero clearance.

I had to do some of my own "fabricating" which meant removing the rubber and cutting down the plastic pieces with a Dremel so it was flat/flush. Lastly I had to go buy longer rear screws bc I just didn't have the shear force while lying on the ground to push the tray up. Using the longer screws as leverage I got the tray flush and replaced with the shorter screws one at a time.

To reiterate... great product!
Super late response, but I'm unfortunately having the same fitment issues but with the stock oil cooler. When the ducts are lined up, the undertray's bowing out in the middle and the rear portion where it bolts into the oil pan is pointing much further down. It takes a lot of force to push the tray up to sit flush and it feels like that can't be right. It's almost like the 2 sides of the bumper are pressing into the tray too much when it's slid in.

Not sure if anyone has had this issue or if I might need the bumper repositioned...?

Any news on the restock?

We are currently assembling trays and processing backorders. Inventory should be updated on our site soon. Normal production suffered delays with being unable to source more aluminum sheets from our usual supplier which caused a lapse in availability.
ETA on restock?

We have trays back from coating and are assembling them to process backorders. Most orders should be going out next week.
PM sent!
Cool video on the tech inside the new Corvette C8 Z06.

23:55 is interesting as they talk about the underbody aero. They talk about the 'stall gurneys' (those plastic deflectors in front of the front tires) and how they are there for drag reduction (aka fuel economy). For the high downforce configuration, the stall gurneys are removed for more front downforce. It needs to be balanced by additional rear downforce as well. This is what Porsche practices too.

I hope this puts to rest once and for all what the front corner felt pieces on our M3s actually do, and why getting rid of them is not a bad thing.

Some weak DF numbers after that GT3 RS release at nearly 2000lbs at equal speeds… That said, yup sounds like they're for improved fuel economy. But maybe there's a better place to move this convo?
deansbimmer's user avatardeansbimmer are you still making these? Have you had time to develop a brake duct compatible with the undertray? Trying to find a solution to use with this undertray without having to cut up the bumper. Thanks!

Yes these are still being made. We have done some custom brake ducts for cars in our shop. It's not likely something to produce as their requirements depend mostly on the lip design and are not one-size-fits-all.

Lips with built in brake ducts simply require some cutting of the undertray to clear the ducts.

Thanks for posting. Great video 👍🏻
deansbimmer's user avatardeansbimmer any update on recent orders?

I think I sent you a PM--but I think I still have a restriction on my account.

will you continue to make these as you go?
I have a splitter that covers the whole flat bottom but will be retiring it at the end of this year and need an 'oem' replacement!
Yes I will continue to make these.
:thumbsup:

Will order one soon.
Four years later bought one and installing right now. Ordered during christmas and still got it in a couple days!

Did you buy it off the mporium website? I ordered mine back in November and still haven't gotten it yet.

We’re shipping backorders currently. This batch took a long time to manufacture and have coated- there was a period we had no inventory.
