Thread referenced by deansbimmer in How bad do I need to replace front belly pan kit? 09-08-2024
Thermostat replacement led to proactively changing a lot of my cooling system parts which led me to drain the radiator and well.... now I am here!

Ordered a tray just moments ago!

I see you offer conrod ACL bearings. It would be nice if you had a pair to offer extra clearance upper main and extra clearance lower thrust main from KING bearings.

My upcoming project is to use KING bearings STD clearance with exception to #1 upper main and the lower thrust main. Hopefully that makes sense.
I'm not aware if KING sells mains individually like this as oppose the whole set.

Anyway....the mporium undertray I ordered is still going strong.

There are no sizing options available for mains. You don't want to vary clearances on the mains, we've seen no issues with the KING main sets out-of-the-box.

This is good to know!

What clearances are you typically seeing with the mains? .0020" there abouts?
I’m assuming that this is the product I need!

It's the exact piece you need. I'm happy with my purchase of this. Just need to drill some holes and mount it up.

Do you still sell these undertrays directly for a better deal?

We’ve only ever sold them directly, were the only source. We blew some out for Cyber Monday. They’re $400 plus shipping.

My opinion of course, but I don't think it's a bad deal to begin with. Biased in that I purchased one, but it's well thought out, good quality, and the added bonus of supporting one of the vendors that's been at this for the E9x crowd since forever.
Just installed. I can dig it! MUCH MUCH better than the OEM bits. If you don’t have one, you’re wrong :D

Looks great!
Was looking to place an order for one of these undertrays and noticed the Mporium website says they're currently on backorder. Just wondering what an ETA would be for them to be back in stock?

Thanks!
Deansbimmer, is there any advantage to adding a gurney flap right in front of the oil cooler outlet to aid airflow out from under the car?

We've not seen any evidence that any add-ons make any difference but you're welcome to try it out with your setup and report back any improvements.
Any promotions coming up for Labor Day or other holidays?
No plans are in place but that choice depends on how the season goes.
