What are the uses for front scoops, and rear wings. Are they just for stability? What speed do they become effective?

They are of little use on street cars, because you should never be attempting to take corners on public roads at the speeds where wings are effective. On street cars, they're for looks only.

The only time I notice my factory spoiler doing something is when it's really windy outside. Then all I feel is the back end get pulled to the ground more. Same thing in the front, hypothetically, it's like an Indy car, the front spoiler is designed to put air in the radiator and keep the car on the ground. However, you will never go fast enough to experience this sensation. Looks good though!

That's what I figured. Does anyone know actual speeds and specs. Just for gp.

If you mean the little wings that stick off the nose corners, they provide downforce. A REAL wing in the rear does the same thing. There are also "for looks only" versions that do nothing.

Speeds vary, but 85MPH is usually when they'll help provide downforce in the corners. BTW - mazda built the sunroofs on the 2nd gens to help with downforce when they're open.

If you mean the front nose lip spoilers, "in front of the wheel" spoilers, etc.., their designed to reduce turbulance under the car plus decrease drag which improves accelleration & fuel economy.

what do you mean by front scoop? you mean the one on the TII hood? because that is for the intercooler not for aerodynamics.

I didn't know that...

This is the one I want to put on my car, but it's the info I'm interested in.

WOW...fc2000....

that will look SWEET on your car. I bet it will really be useful on yor front end while your car sits parked in your drive, you know, after it blows all to hell cuz of lack of maintenance and upkeep....

so you want a $1000 front end but you still havent even spent the $20 that it takes to get the new spark plugs that you need?? GO GO SPEED RACER....

Everyone rags on the stock hood scoop for not directing any air to the top mount IC. It does work, just not as well as some might like under the conditions most people here use the car for - the conditions the car wasn't designed for peak performance under. I'm not talking at a ridiculous velocity either.

PureSephiroth

weren't you trying to get under 10 seconds on a tight budget? You should spend your money on things that make the car work if you want it to run even 30 seconds. You also had a thread on wings helping your drag time didn't you? Please, before you get flamed to oblivion, stop posting spoiler related topics. You won't hit 10 seconds in an NA and you won't be faster with a spoiler or new front bumper. Just get you car up to operating standards, i.e. new plugs, new wires, new fluids, new brake pads, etc. etc.

If you drive legally which you SHOULD non of that **** is doing anything. The stock aero parts do their job under track conditions which means higher than legal speed limits. But they DO WORK. You don't need anythig other than the stock aero parts if you want strictly functional peices. The GTU style wing provides downforce but increases drag a bit. The SPORT kit which is a total of 5 peices I beleive lowers drag from .31 to .29 I think and is better for less drag then more down force.

The RE replica while beutifully crafted and produced is just, honestly now, a ricer mod. I don't mind saying that I like it and I like one other kit that is, according to a friend, "way out there" but it will not give you any performance at all. Your either very missinformed or don't want to get out of denial from what you have heard on this board. Simply put most of the aero kits "body kits" do NOTHING but improve looks and honestly not all do some make the car look like crap and on the same level as other rice crappers. If you want performance start looking for a TII if your into drag racing. And get a ******* education and a good job. Because honestly if money is "tight" your in the wrong game. Speed most definately costs money. I would guesstimate atleast a 5-10k dollar investment to get a Turbo Rx-7 into the 10's with $0.00 spent on body kits or accents to make it look purty. If your going to spend money on making it look nice or whatever just sell the friggin car and hand over the keys to a real enthusiast who will treat it like what it is supposed to be. A god damned sports car. Wasting thousands of dollars on appearance is pointless and distastefull unless you have one fast car that is in perfect tune at which point you have spent enough time building a great well rounded sports machine and you have earned the right to do whatever you want. Within reason of coarse.

PS- sorry about the rant

When I said I wanted to hit 10 seconds, I was being facitious. I guess I figured people would get that. I'm building this 86 to look and run very well. I have already put new plugs, new hks intake, apexi exaust, walbro pump, and a full tune up. I'v ordered new wires, but they'r not in yet. I'm waiting on a new set of wheels, but have to wait till pay day. When I said "Money is tight", I meant I didn't want to drop 15 large in less than a month. I wanted decent parts that won't burn a hole in my pocket. I'm still willing to spend a good chunk of change though. I was asking about wings and scoops because I've heard a lot of different things form a lot of people. I wanted some valid answers from people who knew. I was also looking for actual speeds that scoops and wing come into effect. In the future I will buy a 93 fd3 model, so not every question I ask is for my current rex. Why does everyone automatically assume everyone who posts questions is looking to be the next vin desil? I just wanted info on hypothetical situations. Chill out, for christ sake.

I guess we should have known that when you typed 10 seconds, you were "being facitious". Its very hard to pick that up when you're typing....

Wings won't help you. Body kits won't help you. Paint won't help you. If you want the car looking good and running well, do the maintainance properly and leave the exterior stock. There's nothing else to it.
