Stock FC spoilers: differences? images?
I've been trying to find good profile images showing the different stock spoilers, but the trick is knowing which ones are which. Could you guys post some different profile pictures of both? Unless, of course, S4 and S5 spoilers are the same, but my understanding is that they aren't identical.
Eventually I want to buy a spoiler for my '7, but if I'm going to spend much on something that's mostly a visual enhancement for in town driving I want to make sure I get it right (btw I'm really not interested in any aftermarket spoiler options).
Thx

There are a few profile shots on their, I'm not sure if you checked it out or not. They aren't labled but you should be able to figure out which ones are stock and which are aftermarket.

The last two are S4's, and maybe another one of these is, too. I do know the S5's have the painted to match molding, but on black cars it can be hard to tell from a picture. Still, some of these are difficult to get a straight on side view. From what I can tell maybe the S5 spoilers have a deeper scoop to them than the S4 spoilers. Also, are there more than two stock spoilers for the FC? Btw thanks for the link!

the s4 and s5 spoiler looks the same and has the same mounting points, but the s5 spoiler sits slighty higher than a s4 spoiler/ the s5 has a higher lift than the s4 (also not taking about 87 sport spoiler).

here's a good pic of the sport spoiler, also known as the duckbill, and it's the one you want:

also, I guess you could consider this stock.. it came from the factory

how can they look the same if one's higher than the other?
and if the sport had a different spoiler I'd like to see what that looked like
edit: I just posted and then saw the pics, thanks!
So now I at least know what the sport spoiler is, and I don't like it. Why do you say it would be the one I'd want though?

Because it's the only one that's actually functional! It helped lower the Cd from .32 to .29 on the Sport. I was halfway joking though; get the one YOU like the best.

Are those numbers in the FAQ (or could you link me to wherever)? Because I'd consider it more if I could compare them all based on aerodynamics. Like I said I feel for my purposes the spoilers I would consider are chiefly visual upgrades, but I do value purposeful modifications (past mere visual appeal).
Also, I suspect that the coefficient of drag you posted is for the WHOLE aero package and not just the spoiler, but having a reference should clear that question up.

As to why want the duckbill - ? Personal preference, or possibly that it might actually generate downforce (unlikely) or reduce drag (as posted above), where it is likely the wing spoiler hurts aerodynamics (ie, extra drag, or even lift generated).

It appears I made an error; the Cd was actually lowered from .31, not .32, but you are correct, you would need the entire package to have a Cd of .29

The larger, non-wing style on the dark red S4 posted above, is one I've never seen before except in the odd pic - but its possible its factory and wasn't sold in Canada. The fact the car appears to have turbo side skirts and the spoiler appears to be three-piece makes me wonder if it's factory - why would it need to be 3-piece, since the rear deck where it mounts is not cut by the hatch? Might be a aftermarket-sourced dealer piece.
The car you are referring to has the Finishline aero kit. See here:
https://www.rx7club.com/2nd-generation-specific-1986-1992-17/finish-line-aero-package-435419/
It was a dealer installed option so I'd say it's stock.
This on the other hand is not stock, but cool nonetheless.

It's likely the spoiler is the largest part of the aerodynamic improvement; the only other additions appear to be small strakes added to the sills ahead of the rear tires and to the sides of the front lip, it appears, which could help deflect airflow around the messy area of the spinning tire tread. Wide tires definitely hurt aerodynamics, so that would make sense.

Sorry to go off topic but to answer the question, the plastic undertray for cooling purposes is stock on all models. The aluminum undertray that bolts up directly under the oil pan and serves no purpose other than to help lower drag is the one I'm talking about. It's found on the Sport models as part of the aero kit and may have been on the turbo's too.

What I was saying is that if I can tell a difference by looking at them, then they don't look the same.
This thread has been informational, alas I probably won't be able to get a spoiler for a while, I need to be seriously focused on making the car reliable... BUT, hopefully you guys are enjoying the topic, too.

you cant even tell the difference thats y ur asking, all of the sudden u can tell the difference. pointless thread. u could have easily go to google and look for side pics of s4 and s5.
