Why hasn't anyone made any stock wing spacers? Seam like a logical thing to do. Would look nice with a 3-4" lift. Would need at least 3" for stud depth.

 

Wasn't isn't the main problem that the rear deck lid is too short and low to do anything. So you need a 5in+ spoiler wing to really grab any air?
Everyone is all **** over the 5in lip spoiler but wouldn't that / this type of wing work better once raised up enough to actually do anything?

It has much more surface area to plant the rear. And some spacers would be cheaper that a whole new wing.

 

I don't see any functionality coming of rasing the spoiler up

 

You gotta use your brain a little bit to see it. think of a 3rd gen in an air tunnel. Raising the deck like that get all the down force you want with less drag. Problem with the rear of any 3rd gen is the rear deck lid is to short. When air coming off the car misses everything. Why everyone goes with big lip or monster wing spoilers.

The stock wing was used to raise the deck lid. But its still to short. Get the deck lid into the air stream.

Its a flat wide piece that just really extends the rear of the car up [ not really a wing] then the deck lid is now in the air stream and would get much better down force then a lipped spoiler that makes drag and would have some turbulence behind it.

Its all the stock wing does or did, raise the deck lid at speed. not really a wing at all, just a deck extender. Its all a 3rd gens needs is more down force at lower speeds. So you must get it into the air.

 

thats not true....the firebird deck lid spoiler (the ones on the GTA's) we used up to like 250+mph. the bird was heavily modified, except for the spoiler. they said it was very well designed

 

You stole my idea, I raised mine about 4" and tilted it forward more. I'll try and post some pic's later

 

I don't care how high it is or how far into the airstream it is, the shape of the spoiler itself doesn't lend itself to creating dowforce. A buddy of mine is a physicist and he did a study on the spoiler on a 2nd gen T/A. It produced a maximum downforce of 75 lbs.. Pretty good, but it wasn't until 250 mph You also have to factor in the quality of the air after it leaves the back of the car. If the air is turbulent, or creates a 'dirty' slipstream, this will cancel out any of the benefits you get from the downforce.

 

A friend of mine raised his stock spoiler up a few inches and it looked pretty interesting.

This spoiler is good to 307mph

 

I think the reason most people go larger is not only for looks but low speed down force. Or i assume low speed down force. I know most of the stock ones work well at high speed but what about normal driving and highway speeds 65-70.

 

The only reason for a spoiler on a daily driver is looks. Like what's already been said, the only 'downforce' that you're going to see is if you're going well WELL over the speed limit any place in the United States excepting the Bonneville Salt Flats.

What's that? :P

You ain't gonna see any effects from any spoiler on these cars unless you're going faster than your car can go.

 

if you need a example, look at a dodge daytona. (i want to say 1969, but i could be wrong)

 

OK well then I must have missed something. I though everyone had a reason going **** nuts over 5 in lip spoilers.

I still them some spacer block would look sweet. Its a nice wing for stock. Though I would want to "seamless" so it look like it was still stock just taller some reason.

 

Yeah... for appearance....

 

Do it for looks, Enjoy it for life

real 4thgen wings almost done on mine....

 

I know its dirty and there's still some sanding to do on the spacers blah blah... the pic's don't do it justice

 

A front view...

 

See I knew I wasn't the only one. Details n more pics please. Looks like you changed the angle some. That was my only real concern. if they match the same profile as stock, the wing maybe hanging over the bumper more than the deck.

info info info PLZ

take it apart n show some pics. Looks sweet.

 

When the 3rd gen body first came out it was the most areodynamically efficient body produced up to that point(by gm). Even if you went 150 miles an hour that little spoiler wouldnt make a difference Ri cer Plus it looks like crap

 

It's welded on, so the step by step picture oppotunity is over. I'll try to explain how I did it...

I took three 1" U shaped pieces of metal and welded them together for the extensions, drilled holes for the spoiler mounting bolts and bolted them down. set the spoiler on the car. I didn't like the angle at first so I did some grinding and more welding to the U shaped brackets. Once I was satisfied with height and angle of the wing, I welded tin over the brackets, it wasn't straight so I had to lay a few patches of bondo over the tin covered U brackets. Thats pretty much how it still is, haven't had a chance to finish sanding it yet so I just spray painted so I could drive it without the brackets rusting. If I was gonna do it over I would find some better pieces to work with for the brackets, I was just using scrap metal that we had laying around the garage.

This is how it should be made if someone was going to make them... and you would still be able to remove the brackets from the spoiler with, say, a 1/4" extension and swivel head?

 

You sure wont like this then. Id build one if I had disposable income.

But your only pointing out the obvious. Its already been discussed and we / I know the wing is only for looks. I also know the 3rd gen is an aerodynamic nightmare when you get near 200mph. Least n drag racing. I watch a guy on TV say he needed to step it up to 2500HP to break 200mph in the 1/4 as the sleek looking car might as well be shaped like a brick. Not sure on the class but the cars were stock looking all steel but monster power.

 

i just cant stop shaking my head.

how did you do them headlights? any pics?

 

Still having a hard time picturing what you mean.
