Wing measurement please
I am putting a rear spoiler onto an '82 hatch and am hoping someone could send me a measurement. I would like to know what the distance is from the top of the hatch to the first hole.
Right or wrong, I really think the 928 was born to have a one-piece rear wing. And now I have one. ![]() Thanks everyone. ![]() |

The measurement down to the first bolt is 43-1/4 inches. The think that will give you problems is that the hatch for 87 and up cars has an indentation for the mounting hardware on the underside. I saw a write-up somewhere with pictures that someone did for installing a wing on early year cars.

I read that Porsche engineers once said that a wing on a 928 was unnecessary.
Has anyone else read that?

The measurements may only work for a stock wing. Some aftermarkets dimensions vary. You will have to cut a hole to the inside camber of the hatch to mount the bolts if you have a non S4 hatch.
You can also measure the long way between the mounting locations on the wing. If you transfer that dimension to the hatch it will only fit 1 place as the hatch is tapered

I've heard that the wing is not necessary also. The thing you have to remember is that any appendage on a car will have effect on the car: wings, spoilers, tails, etc. They are generally intended to create downforce to help the car stick to the road, and also used to stabilize the car. Most wings, spoilers and tails will do just that but at a cost....lowering the top end of a car because to be effective, they will create drag and if not installed properly (mis-aligned), they will make the car feel unstable. The effect isn't really noticable until you reach speeds above the legal speed limit. In the case of my 911, on a windy day the tail can make the back of the car wiggle a bit as it approaches triple digits but the car is only 2600 pounds.....Just food-for-thought.

I too, have read that about the rear wing on a 928..."Not really needed"....But, I gotta admit...The S4 wing looks pretty bad ass! LOL

I was a bit hesitant to take the drill to the car as I have been doing the measurements as you've described them all the while checking for horizontal alignment and vertical alignment (over the back end); hence the measurement request. Quote:

Thanks everybody. |

Just remember to take your time and get it right. And think ahead of how you will do it before you even touch the hatch because once the drill bit touches the hatch you will be at the "point-of-no-return". Search for that article on doing it. MPDano might have it on his post at the top of this forum.

Be Sure To Use A Center Punch (machinists tool to mark the hole location) where you plan to drill so you don't skip the bit down the hatch an inch!

Here is the posting on MPDano's thread. It starts at post #65.

Wow. This is just what I needed!. Thanks for the post! A question to Leo: did you fill the cutout? I was thinking of using some clear silicone or Bondo's not-so-permanent filler that comes out of a mousse-like container, dries semi-clear and can be easily removed--usually in one piece. |

Try this for filling the cutouts:

It's on and looks great. So good, in fact, that my wife said that she would like to take it out for a ride and did. :-)

That's great. The measurement I gave you was from my S4. They make plugs of various sizes which would make it look original to the ones that don't know any better. Post some pics before the tape. You might get some ideas on what would work for cosmetic plugging & sealing.
