cayman r wing on cayman s

[Otto]

hey everyone

i am looking to improve the look and track function of my new-to-me cayman s

i have an opportunity to get a cayman r wing from a guy

if i do this, will i need to disable the existing active wing? - pull the fuse? - remove it? - cover the slot?

i know there is an entire unit in there that lifts and lowers the wing, and it could save some weight if i take it out

any advice?

i know i need to add the front spoilers as well, but i can get those at suncoast or get after market

Stay below 80 and you won't have to worry about the rear spoiler raising, Otto!

Removing the spoiler mechanism is easy though you will have to noodle out a way to mount the original spoiler cover - or something else - over the original spot. I think the R wing mounts to the hatch lid. I don't think they actually interfere, though.

[Otto]

no, it hurts my car to go so slow :-)

i think i could just remove the fuse of the active wing and let it just be there and not function

however, removing the works would save some weight :-) not that it maters in my case

[Dandelion]

You might not be able to simply disable it - the existing wing installation may block the R wing.

but otto we'll all know itz not an R we've already seen it

imho only cayman wing to get is the MrMrsBMAN mighty cayman wing of destiny

[N0tt0N]

But we promise not to say ANYTHING.

i agree jd, but i can get the cayman r wing for $400 on the used market

really like the nr gt3 wing for cayman as well!

just looking for a little style and a little down force :-)

[N0tt0N]

I like the Not-R-Auto (NRAuto) version, too. You'll look Maahvelous. I've always wondered if anyone has actually tested these to see if they actually add downforce. Seems the manufacturers would post drag, negative lift, and the chord design if they were more than, gasp, cosmetic, right?

Find out where B-Man got his Chingon Wing

[Otto]

well, if i added the bman or chuckh wing i would be forced to add extreme front spoiler or face certain death when the front wheels lift off the track

actually, with the nr gt wing they recommend the gt front bumper or front spoiler as well

i just wanted to add the cayman r front spoilers and the used r wing i found

suncoast has it in a kit...

In addition to the wing that goes on the rear hatch, there's also a piece that goes on the bumper cover to cover the hole left when the regular wing is removed. Make sure you get both parts.

You can leave the existing wing mechanism in place. However, you will need to go to the dealer and have them disable it. It's possible that someone might be able to do it with the Pro version of Durametric, but not sure. If you leave the existing wing and mechanism in place, you wouldn't need the piece that goes on the bumper cover, but that's weight that could be removed.

Also, Porsche recommends that the R wing only be installed in conjunction with the matching front bumper lips. Not sure how vital that really is, but Porsche claims it will upset the balance of the car if both ends aren't done.

BTW, the R wing does not actually provide downforce. The best it can do is reduce lift. IIRC, the lift reduction is about 50% of the "normal" lift.

billc you have me scratching my head now

what is the difference between less lift and more down force? :-?

this weekend was the first time i have even driven a cayman at speed

the difference from my 06 boxster s was amazing on many levels

however, i could feel the rear end lift and the front end dance at speeds approaching 130mph at various points on track - so much so that i backed off a bit several times

[Dandelion]

Less lift = there is still less overall weight on the wheels at speed.

Downforce = more overall weight on the wheels at speed.

It was pretty windy around here. Could you have been feeling wind gusts, especially on the back stretch, which is very exposed?

[vranko]

^ if you really want to feel those gusts (which I thought were fairly minor last weekend) drive my Golf! It's a box with wheels. :shock:

[Otto]

yes, that too

Downforce = "negative lift".

Just at a high level: So, every production/sports car produces lift at speed. i.e., they actually get lighter the faster they go (usually by many hundreds of pounds at 120mph). Only the most sophisticated, aero-focused race cars are actually producing true downforce at speed (i.e., making the car get heavier at speed).


The "wing" on the Cayman R allows better flow than the little speed-activated spoiler on the normal models. But at best, it's still not really impacting downforce. Think of it more as a stabilizer -- it will help make your car feel more stable thanks to more efficient flow, but because its impact on the car is still extremely small, it's not worth saying the wing is capable of any appreciable amount of downforce.



It does look good though!

http://en.wikipedia.org/wiki/Aerodynamic_lift It doesn't take much of an airfoil to create a huge amount of lift. Look at the small wings on some of the commercial jets and how much weight they can lift. By having a wing on the rear it creates downforce through aerodynamic lift but inverted. To say you can get more downforce with less lift is not a valid statement. It probably also aids, and this is only a guess, to reduce induced drag from the large rear end of the car, and yes the rear end does create drag.

Like Otto, I found at about 120mph in my Cayman S that the front end began to lift. At 140 I felt it was time to pull back on the stick and go airborne but I'll save that for the airplane. I found some front splitters on Ebay in the $300-$400 range. I need to get these on my car as well.

My buddy Scott from PA, also at VIR, added a Cayman R wing to his 09 S. I'll ask him what he did to deactivate the automatic wing and pass it along.

When the discussion of lift comes up it should also include a discussion of angle of attack and drag. So here is something for you to ponder regarding drag. Which has more drag, a round bar or a rectangular bar......and why?

"Less lift" means you have reduced the normal aerodynamic lift of the car, but haven't reduced it to zero. "More downforce" means that you have not only completely countered the normal aerodynamic lift but are actually generating a net downward aerodynamic force pressing the car to the race track. Basically, the two phrases are describing the same thing, but they are relative to which side of '"zero" the car is on.

however, i could feel the rear end lift and the front end dance at speeds approaching 130mph at various points on track - so much so that i backed off a bit several times
Getting light at both ends means the car is still fairly well balanced. Adding a better wing or spoiler at the back without doing something on the front will actually make your front-end lift worse, not better.

[roundel]

buy a Redbull. Its cheaper and easier to install.

[Chopper Dropper]

Be aware Roundel does not like down force, it keeps the car too planted.

Otto, I recieved a lengthy email and attachements from Scott on the R wing install. PM me your email address and I'll foward it to you.
