Default Who still uses the plastic undertray?

Life took a turn that meant no turbo for now, and I am just enjoying the car stock and learning how to autocross.

Lame me got lazy and paid a guy to change the oil last time and when he re-installed the undertray he put the screws in the wrong holes, so for the last 3000 miles it has been occasionally bumping into stuff (hanging too low).


I am trying to decide wither or not I want to ditch it. Who still runs the stock plastic engine undertray? Is it necessary/desirable for a stock 01? What about once I turbo it? When fabricating a similar undertray, what material are we using?

Good to see this place is still hopping. I miss the kitty in the logo though.

Strange... I did a search on the actual MT.net site and it didn't catch those threads.

Thx for the help. Now to find the missing screws. I imagine they are easy to find...

you have to think... Mazda had to pay someone to design that under tray thing and they had to pay for thousands of them. The wouldnt have done all of that if there wasnt a purpose for it. Mine ripped off unfortunately.

I don't know how much they are from Mazdaspeed, but FM has starting carrying the trays. I bet shipping would be very expensive though.

For the record, my reasoning behind ditching it is that I fear it may have been mangled so bad that it is no longer usable. I wasn't thinking about throwing it out, I was more concerned about if I need to replace it with something if it is trashed, and if so, what should I upgrade to.

I have tools to bend metal at work, and I am thinking of duplicating the stock one out of stainless steel or aluminum, but I worry about the noise from it "oilcanning." I know there are things I can do to make it stronger and more rigid, I am just going back and forth on wither or not it is worth my time and money. I am looking into aftermarket solutions as well.

Brand new OEM undertray for your car is $55. It's lightweight so shipping isn't bad. That's what I did. No brainer IMHO.

COVER, UNDER (NA01-56-111F) - $55.51 - NA0156111F

Hornetball you are awesome. I never thought to check for a new one because I am so used to owning obsolete autos. Do they fold up the thing or is it shipped in a large box?

Comes in one piece in a large box, but it's really not that large.

Could you not just install the bolts in the correct places and have it at the correct height?

Do the Beatrush/Cobalt aluminum trays accomplish the same thing? My MSM didn't have an undertray when i got it, and still doesn't. I need one.

I just did an "estimate shipping" on that, and to 92081 (San Diego county) it came back as $51.96 for shipping via UPS Ground, and $99.14 for shipping via USPS.

For those who lack an undertray and can't find one locally, why not just pick up a sheet or roll of ABS plastic (or similar) from your local supplier of such materials?

I ordered mine back in 2010, and got both the undertray and the air guide (both lightweight but bulky). Rosenthal charged $20.65 for S+H on the entire order. Pretty fair.

Obviously, VA to TX is a lot different than VA to CA. But OP is from IL, so his shipping rate is likely to be more like mine. Also, I think what UPS charges outfits like Rosenthal is vastly different than what they charge the average individual (or Rosenthal eats some cost on bulky items and makes it up on small stuff -- who knows?).

DIY is always an option. On this particular component for this particular price (including shipping), I'm satisfied with what I did. I agree 100% with your point about taking S+H into consideration when weighing options.
