The choices for wings are almost endless. I have added some of the more popular ones here, and tried to limit these to ones that are specific to the RX-7. i.e.- I didn't add any of the universal ones that will bolt onto any car.
email me with photos of any more or if you have beeter photos of the ones I have listed here.
This is still a great looking wing, and is subtle compared to many of the big ones that really stand off the rear deck by a foot or more.

Date: Sat, 24 May 97 18:02:00 EST I got my spoiler back from the paint shop today, and mounting the thing to
the hatch turned out to be a 1/2 day job. Here's my report.
The spoiler arrived NOT primed, with 1 page of instructions for mounting
and painting. Some sanding had been done, to remove mold flash, but there
was a slight ridge on the left side inner pylon that had not been sanded
smooth and round as on the right side (my paint shop took care of that).
The spoiler has 8 mounting points, 2 on each "pylon", with a stud in front
and a recessed nut in the rear. Of those, 6 were easy to reach from
inside, apparently matching the factory spoiler mounting positions. It
came with all necessary hardware, adhesive backed foam gaskets for each
pylon, plus 5 (only 5?) mastic washers, and 5 (?) drill guides.
The drill guides were useful in locating the rear holes, but getting the
holes for the front studs located was a challenge. All this time I was
wondering, after the holes are drilled, would the thing mate to the hatch
surface?
The answer: NO. The rear part of the inside pylons were almost 1/4"
above the surface when all other points were at the surface. That meant
the provided screws weren't long enough to reach the recessed nuts - I had
to get longer ones, and once having pulled everything into position by
tightening all screws, it's certain that the spoiler is under some stress
and the hatch sheetmetal is slightly deformed. Fortunately the deformation
of the surface is hard to detect, and the final result looks completely
stock.
Other minor gripe... one of the pylon gaskets didn't have the hole for the
stud in the right place.
Overall rating - 3 out of 5 stars. I'd have rather paid a little more and
gotten something which matched up with the hatch surface better.
The hatch struts (on this 80 degree day) aren't raising the hatch now...
without the spoiler they were working pretty well.
Now, who wants to sell me their OE chin spoiler from an R1/2?!!! I think
the Racing beat chin spoiler looks goofy when painted body color; has
anybody ever used one of those but painted it flat black? Pictures?

Date: Fri, 12 Sep 1997 16:07:30 +0000 Here's some data for everyone on the 3rd gen. This data is out of
'Race Car Aerodynamics' by Joseph Katz on page 18.
Aerodynamic Coefficients of (1993-)1995 Mazda RX-7
Also interesting is the Aerodynamic Coefficients of a newer BMW M3
I gave both tables of data to demostrate that just because you induce
LESS lift (but not negative) doesn't mean you have to create more
drag. The stock rear spoiler on the RX-7 is actually mainly for
looks. It is possible that it helps lower drag as someone mentioned
but you would have to wind tunnel the car with just the front lip to
see if the Cd is higher than 0.31. From looking at the wind tunnel
tests I have of the FD, the rear spoiler looks basically
non-functional to me but then again, I'm not an aerodynamist so I
wouldn't know.
Another interesting car to look at is the Ferrari F355. It has no
trick Whale Tail, Supra Style, Banzai attack ninja spoilers yet it
acheives an estimated coefficient of lift of -0.24 or 170kg at
290km/hr (374.8lb @ 176.6mph). The underbody they use helps that
much. Alot of people don't ever look at underbody dynamics, then
again I doubt many people would actually pay the money it would cost
for underbody panels considering how much it would cost for proper
development.
Don writes regarding the new rear spoiler on the '96 - 98 RX-7s (the
3rd gen is still sold in Japan). The new spoiler has only two
uprights instead of the four found on the R1/R2 spoiler. --Steve
Date: Wed, 18 Mar 1998 01:44:01 EST The Efini (Mazda of Japan) wing, rear lights, side marker lights, and other
updates are available here in the states from only a few vendors, but be
sitting when you get their prices. They come painted in stock colors, with a
paper template to guide drilling holes in the hatch and mounting.
I have the rear wing and rear lights on my '93 Touring, got them from Peter at
Elite Motorsports (Tel: (714) 551-3294), who has been great to deal with.
This Feed wing looks a little generic - it is probably not designed
specifically for the RX-7.
mazdarx7@ziplink.net (John Levy) John responds to my request for info on a GT2-style wing (an actual rear wing), with end-plates,
adjustability, etc. Like on the Vipers running GT-2. --Steve
...Derrick Hansen of Desch Motorsports. I have had one on
order for three or four months now. Phone # 905-738-9622. Derrick is a terrific
fellow. The wing is designed by him and used on all sorts of race machines.

David Ieroncig (Rx7@Rocketship.com) was kind enough to send me the following photo
of the wing that John Levy and someone (I forgot who, but the photo is labelled "J Eppley")
have:
From: Stephen J Lee Here a couple companies that specialize in racecar bodywork ancilliaries
(e.g., rear wings, front splitters). I only have the phone numbers.
If these guys can't get it for you, drop me a line. If anybody else needs
to find somebody who can make a six speed sequential tranny, redo your
whole suspension, or pretty much make a racecar for you, I've got
thousands of numbers.
