Upgraded Spoiler For 2000 Boxster S
 

I put this on my Boxster. Love it.

1997 2004 Porsche Boxster 986 Turbo Style Rear Wing Spoiler Painted | eBay

I have seen that auction before, and I agree, I like the looks of it too.

My concern would be the functionality. How do you/we know it would have the same effect on the aerodynamics as the stock item?

I'm with you on that matter, I track my car.

I like the looks, hate the finish and fitment.

Mine will likely be replaced with Cayman parts.

Since driving at the speed where a spoiler would have any benefit is highly unlikely (I keep it under 85 or so), I went for the look. The paint was a perfect match and color sanded. It fit just fine. I did have to cut the allen key to get it to be able to put in the bolts. It really changes the look of the back.

the spoiler deploys at 75 for a reason

it does look nice

I love the look of these but if you take the time to notice you can absolutely "fee"l if your spoiler works, no need to a tape test.

Find some long straight back road where the speed limit is around 55 and you can safely travel over 60.

You can absolutely feel the effect that the spoiler has on the car. It's adds more "weight" to the rear end and makes passing and long sweepers much more planted.

Would love to drive a boxster with stock spoiler and one without back to back and see what's different.

Couldn't you just pull the fuse to do this test?

I almost jumped on one of those years ago but posed a question about functionality to the PCA tech question and answer board on the PCA site. The answer I got is that the Boxster has an "air dam" not a spoiler. The large surface area has been engineered in to keep the car stable at speeds over 75 mph. It is doubtful that that spoiler can have the same affect, however, it would be cool if someone made one that fit on over the OEM one and maintained the "dam" part as I think it has a better look than the cheap OEM plastic piece.

OEM is actually a spoiler (also referred to as an air dam) who's job is to disrupt unfavorable air flow. This is a WING whos job is to provide downforce.

However, since this style of wing is used on the cayman, which has a similar shape, weight and weight distribution, it is conceivable that the use of the wing could be ok.

Assuming this wing actually does create downforce, the issue lies with the front/rear balance of the downforce at speed. The wing could generate more downforce than the front and cause the front end to go light.

I agree with most of what you say, however, the Boxster, being a convertible, would have different downforce characteristics with the top down than a Cayman with a sloping continuous hard top body, so perhaps the "wing" type spoiler would not exhibit the same downforce on a Boxster as it does a Cayman. Having a light loose front end at higher speeds is not what you want.

I agree without the smooth transition onto the back, there probably isn't much laminar flow. And there is a reason why the 987 boxster uses a spoiler but the cayman gets the wing ;)

Actually
 

It would kinda cool if you could have both, the spoiler on top and the airdam under it as it came

I want someone to make a small wing like that but that mounts on top of the OEM blade spoiler. I have cash in hand ready to go. In my opinion that would be the best of both worlds. You retain what Porsche engineers deemed acceptable for traction/performance with the addition of some added downforce/looks of the spoiler.

I mean a car with an actual spoiler. But not the stock air dam. How would a design like the one the OP bought feel for instance?

+1 as the OEM plastic "spoiler" part is ill fitting and dull.

I noticed that the 'finished cover had come off while driving, the metal top is still there. First thing that came to mind was 'Now I have a reason to buy one of the upgrades, Cool.

I would be interested to see wind tunnel results of that

My guess is the wings does very little as the airflow is disrupted by the airdam

also looks kind of stupid IMHO

If you have a wing, you really need to have the correct suspension including coilovers and probably some front aero as well

I'd buy something like apswater bought if it could be attached with the air dam part still on.

Unfortunately if you desire a wing you need the underside space where the low pressure is generated. That means air space under it. Otherwise one ends with a spoiler lip...

Whether or not the wing is the right shape down force value or actual works is a whole other matter...

I kinda like the bi-plane look

Go BIG or go home!

There is the old Rieger spoiler (probably NLA now)

Yeeeeeeees!

That Rieger spoiler is " close " to what I want but I do not want a space between the top of the OEM blade and the bottom of the spoiler. Basically I want a mini ducktail where the base/bottom of the ducktail mounts to the top of the OEM blade. So when the ducktail is in the down/parked mode it looks like the spoiler that started this discussion. And then when it is in the up position you would see the blade and the ducktail in the up position but they would look like they are one.

The problem is non factory spoilers/wings may give you a look you want, but unless they have done wind tunnel testing with a particular shape, you could really mess up the cars high speed handling and safety.

I know a guy who does his Cayman aero testing at University wind tunnel here......he is a World Challenge driver so he actually needs and utilizes it.

...So if you are into fostering thesis study work head to your nearest universiy wind tunnel and get your wings and splitters on......baby

I have one but it came from Fla. Perfect color match.Better than OEM ? It doesn`t like crosswinds at speed.

I can't read the original post because someone is on my ignore list, but I know the spoiler.

Fit and function are terrible. Looks stupid. Another FAIL by OP. Nice job screwing up your cars aerodynamics. ;)
What good is that teeny little thing supposed to be? Hahaha! :D

..........

That is kind of my point.

You hang this crap on the car and who knows what it will do aerodynamically.
Could improve or could degrade and possibly make it unsafe

It's a little like the "tuners" that put these big wings on a front wheel drive car.
Do they actually give any performance improvement or just look dumb ass stupid?

Might as well bolt on some potatoes to improve the performance
(not picking on you Charles)

who are you ignoring? ;)

The OP of the thread. :D
At least he has finally figured out how to post things in the correct section.
Yeah, I'm being a bit juvenile :p

Reading through this thread got me looking for some good wind tunnel pics online, which led me to the TECHART Gallery.
When it comes to high performance automotive mods, I am fairly ignorant, but the same basic principles that apply to aircraft should apply here. High speed and low speed flow will be different and changing the shape of one part alone, may have an undesired effect in other areas.
Want a new spoiler? Why not spoil the whole car:

Yes the thin skinned particlewave blocked me because he got schooled when he scolded me for posting something where he, the the self appointed police of pubs, didnt think I should post because it "Cluttered" the pub. I told him scolding people cluttered the pub and hence, yes he ignored me like a typical anal pub rat.

I like the spoiler, I could care less abut "performance" since I live in LA where you are lucky to ever go over 50 miles an hour. it looks so much better than nothing since my spoiler never deploys.

Not very smart to pick a fight with one of the most productive members of this forum.

You want to be a jerk like the Jonathan Lumphead, go right ahead. See how far it gets you in people helping you.

As I am in LA often, other than rush hour, you generally can go much faster than 50.
Just don't kill or injure anyone else because you put some dumb looking piece of plastic on your car and it makes it unstable

+1. Good call.

Hey I am not the one who started things by first ignoring someone who didnt accept his self appointed policing activity and then bring it up on a conversation I started months later. A little short sighted of you boys to suggest I started it by insulting your grand master. secondly, I simply said I like the spoiler and for me it works well. If you don't like it, don't buy it. Having a lot of useless posts does not make one a "productive" contributor. Helping people with information and experience does. Amazing enough, the spoiler I showed is very similar to the spyder spoiler. Again, I just shared that I liked it, it fit very well and the paint was perfect. It also looks much better. Take it or leave it. Telling people things are stupid is just more of you trying to force your opinions on others. Typical behavior from people who spend way to much time on pubs. Now, can we get back to being useful?

I do believe Particlewave is one of the most helpful posters here

As far as the rest refer to post #36

to clarify
Putting aero stuff on a car without doing aerodynamic testing or at very least calculations using computational fluid dynamics applications will yield you unknown results and could be dangerous causing for example instability and then causing the car to go out of control putting innocent people at risk

If it was aero from Porsche, to probably has been tested from outers, especially crap from china, unlikely it was tested

And the only thing I do in a Pub is drink beer
