FD Under Belly question
Is the part labelled 56-111B, "Cover- under front" the under belly pan that directs airflow into the radiator? I don't have one, and I really think I should. Just wanna make sure I have the right P/N before I go ordering it.
Anyone whos ordered one before, how much did it cost you? I plan on calling Ray Crowe at Malloy, just wanna know what I'm in for.
I can't seem to decipher the way it mounts. How may of each of the little clips and such would I need? It looks like theres quite a few, but I can't really tell which of the front two go where.

Yep, that's the one. Part number FD01-56-100. I think it's around 125 from Malloy. It mounts by fitting underneath the front spoiler and aligning with those holes, a pair of screws into the crossmember, and 2 pair into the frame to the front and back of the swaybar. So you might need 6 of those M6 flanged screws with it (or use M6 screws plus washers). Just don't skip the washers, or overtighten these screws when you install it.

The stock undertray is $180 I believe at Malloy. That's at least what it was last time I checked about a month ago. I could be wrong though.
I'd say save your money, and make a custom undertray yourself. All you need is a large peice of say...plexiglass, if you wanna go durable yet cheap. Put your car on stands, grab a tape measure, take some dimensions, see where you're gonna attach it (id take it as far back to right before the oilpan if i were you), and you're good to go.
The plexiglass is cheap like I said, and it's thin and lightweight. Also, it's see-through, so you can see an fluid leaks. And since it's cheap, you won't be pissed when your undertray gets destroyed (which it will...it's one of the most frequently destroyed exterior peices).
Oh and best of all, it'll be completely flat and straight, forcing ALL air from the nose into the engine bay, instead of back under the car, so you get better cooling, and decrease lift under the car, bettering your aerodynamics.
Just my $0.02

Sounds like a decent idea, but doesn't the stock under-tray have all these little grooves and fins, not to mention the duct for the radiator? I find it hard to believe that a flat piece would function as effectively. Mazda would not have gone to the trouble of engineering it.
I'll probably get the factory one, if it gets mangled I'll look into alternatives, but thanks for the info anyway.

Yea the stock undertray is full of fins, twists, turns, and dips. Not exactly what I'm looking for.
That, and why does everyone always speak of Mazda "engineering" things? This is coming from the car in which miscellenous bolts continue to mysteriously appear, cheap plastic clips hold entire panels, door handles are guaranteed to break, undertrays obviously weren't meant to last, ASTs inevitably crack, precats destroy engines, cats clog, and ICs are whimpier than the one in my friend's volvo?? lol
The reality of it is that while Mazda designed an incredible high performance vehicle, they did it on a VERY tight budget, and hence embodied that incredible performance in the cheapest shell they could find. That was the only way to keep costs at only $30K or so. So my trust in Mazda's "engineering" is a little less than yours haha
Oh and just so you know, numerous major racing 7s have undertrays in the same fashion as the one I was describing to you, whether it be like the C-west one (pictured below) or the Mazdaspeed one, etc. It goes hand-in-hand w/ the rear diffuser for aerodynamics, and I can't see how slits in an undertray would benefit you if you're trying to keep air IN the engine bay, since the whole point is to NOT allow it to vent right back out.
Sidenote: what's this about a radiator duct you're talking about? The undertray has one??

Call Malloy, and ask to speak to Kelly. She's handling Ray's RX7 stuff while he's on vacation. Hopefully she can help you out.

No problem, John seems to know about our FDs. He made me alil package deal with nuts and bolts I need to get my front end together. Seems like an 'OK' guy..
1 888 533 3400 Ray or John at Malloy Mazda.
Under body pan: $137
Brake ducts: $70 each
Hood stops: $3.10 each
Misc Bolts & Nuts: $10
John said I should have all these parts by mid next week. I still have to call back and make sure he has everything I need just to be safe and not get wrong things or missing items...

There is no radiator "duct." He is referring to the belly pan which prevents air from going around (below) the radiator.
The brake ducts came on R1/R2 cars and direct air from the lip spoiler inlets to the brake areas.

I have an R model, and yea it has brake ducts, but those have nothing to do w/ the undertray, right?

Thats also the reason that I don't wanna just put a flat piece of whatever under the car as FDNewbie mentioned. Mazda, say what you want about their lack of engineering, obviously thought it was important enough to engineer this piece with a bit of care taken to direct air to the radiator. If it was important enough to do that, I'll assume they tested it to make sure it optimized airflow to the radiator.
