I purchased my car (86 GXL) without a spoiler, apparently it had been stolen off it as the story goes anyways there are some big *** holes in the back of my car, the question I'm asking, if you can tell form the crappy pic, was it a stock spoiler, it wraps around and extends all the way down to where the bages are and goes around the brake light.
if anyone has pics of a stcok one or one that looks like it might be the same one I had post them

Thanks,
Chris

 

I thought the holes for the spoiler were on the top of that peice of metal not the side of it.

 

It was a stock spoiler, the gay version. Thre were two: versions: The s4 sport vesion, and the TII/gtu version.

 

this is the sport style:

 

It is probably the sport spoiler that have been there once.
The T2 spoiler has less bolts than the sport.

at first i thought the picture didn't fully load, and then i realized what i was loing at. I think the gtu/tII version looks really nice, you'd prob'ly be able to go pick one up from a junk yard or someth

 

Which one gay??? the sport one.. It might be gay, but it's better than no spoiler.

 

why's that?

 

i didnt have a spoiler for awhile. Than my friend got a 7 and wanted to buy a "ricer" wing.. so i told him to sell me his wing for 50 bucks.. lol YEAH! nice wing in good shape for 50$.. Needless to say, 2 day's after he got his "ricer" wing, it got stolen, lol, he was pist.. but that's what he gets

I'd rather have the Turbo/gtu wing, rather than the Sport wing

bah... i guess it's all preference.

The Sport wing actually works for the cars overall aerodynamics. I think it looks PIMP

SPORT!

 

Hey, the S5 and the S4 GTU spoilers look diffrent right?

 

both the stock wing would reduce the tumble of the wind off the back of the car. i'm not sure if there's much since no one ever replied to my thread about airflow....

 

Yeah there are actually three spoilers...

The Sport style (which actually helps aero dynamics)
The 88 GTU Style (which doesn't lower aero dynamics but most people think looks cool- raised wing and all, also found on the 88 T2)

and the 89-91 GTU style (again a raised wing, just slightly larger than the 88 GTU style, and no help what so ever for lowering aero drag).

 

Like usual the Markster OWNES JUU!

 

gonna call you on this one. i'm not going to argue about drag coefficients since they're pretty useless. but do you have any proof of the gtu wings not helping the airflow over the rear of the car?

 

Yeh that is what i thought. because my GTU spoiler looks a little better than the one showen in the pictures above.

 

No, it was done in tests back in the mid-'90s. The GTU style while it did increase downforce actually raised the drag coefficent.

While the Sport style considerably lowered drag (Cd) typically by .016.

Since an unspoilered GXL using 205/60-15 tires and the baloney slicer wheels has a drag Cd of around .32 (actually just under that, like .319), just putting the sport spoiler on it lowered the CD to around .30. Further drops can be found using the other Aero parts from the Sport such as the underbody panel and the wheel skirts (typically down to .29).

But the GTU style typically raised the CD up around .02, because of the increase in drag brought on by the minor increase in rear downforce.

Funny how you almost never see Mazda publishing anything about the Cd of the coupe after the the GTU style spolier came out. Only about that the spolier helping with downforce.

And while you may think that Cd has nothing to do in the free world, it directly influences how a car handles at high speeds (read above 55 MPH) and freeway gas mileage.

Also remember that those number were based on the S4. The S5 (with all its parts) was actually a little better aero dynamicly drag wise than the S4.

 

I got a sport weeeeee!

lol

Damn Mark is a damn data bank or mainframe of knowledge. You have crap loads of info in that brain of your man.

Sport!

 

the sport spoiler reduces drag...mazda said upon it's release it was more effective at cutting drag than larger ones...looks very porsche 944..thats why I have one soon to be replaced with RE Amemiya type 4 siting in my basement - it may night be functinal but it looks mean and (and finally my TII swap will back up how the car looks hehe).

 

my problem with Cd that it doesn't seem to equal real world factors. the FD iirc had a Cd of .31 while i've seen golfs and such have them at similar levels. this to me seems like a pointless number then.

not to sound like a jerk, but if i saw a wind test pic of all the different variations i've be much more likely to agree. ironically this is what i asked for a few weeks ago to no avail....

 

None of the pics I've seen so far look like they would be the right one, if you look closely on the original pic you can see some lines where the spoiler came down to the badges, it appears that it wasn't a raised spoiler, but not like the sport, because the sport doesn't wrap around. As far as I can tell it was some thing like a late eightys mustang hatch back spoiler.
I drew some lines on the original pic, to show where the lines are.
P.S.
Thanks for all the help

 

The sport spoiler does wrap around.

 

The pic of the sport spoiler posted by c-squared doesn't go all the way around, see my above pic, the holes go all the way back to where the line ends

 

I will post a pic of my car. Sorry about the dirtyness:
