Was there ever a option for a rear wiper delete on the old cars? and if so was the S rear wing modified?

Thanks

Tony, I see you are all over this. Did Jerry ever have any luck with this?

Hi Brad, Focusing now on getting Just Peachy on the road. Am now leaning against spoilers on the ol gal, but I am still vacillating on which way to go. Matt "The Fixer" has done a nice job on his custom fabrication and those Audi TT rear spoilers look good to. Might want to pm Jerry Feather or Erik N and see if they have come up with something lately. Good luck. T

A bare butt is always inviting. A spoiler take that smooth thing and disrupts the lines (although it does give you something to hold on to)

I'll be giving this stuff a go, to fill in the wiper cavity, as my project moves further along. VersiMold:

In the Thread that Tony linked in post no. 2 above, you will find the process that I suggested for use of what is probably a similar material to this Versimold to fill the wiper void in the S spoiler.

My material suggested was Devcon 80 and is a two-part urathane product that cures very much like hard rubber. Look at my posts number 23 and 26 for the material suggestion and my description of the process for what I think might be a nearly seamless fill of the subject void.

One thing that I notice that I left out of the process is the need to thoroughly wax the surface of the spoiler that you will be using to mold the surface with the epoxy you will use for that. It needs to be waxed so the epoxy will release from the surface molded when the mold plate is fabricated. Otherwise you may end up with the plate permanently stuck to the part of the spoiler where you are trying to duplicate the surface texture for the surface of the void fill.

Later in the thread posted by Tony I also suggested where I thought this idea had actually lead me and that was in the direction of a sort of hidden retractable spoiler sort of in the theme of the one on the 964. I actually started with some development of that including setting up a spare hatch with the Plexiglas piece for the surface of the spoiler, developing the geometry and a mock up of the hinge mechanixm, designing the retract mechanism and much of the linkage, obtaining some of the hardware for the linkag, obtaining some filled epoxy for molding the body of the spoiler itself around the heavy aluminum backbone around the outer edge, and then setting it up outside to start some fabrication.

However, time and space limited my ability or desire to progress with it and it finally got snowed on and left to hibernate. I haven't gotten back to it yet, but may some time. However it will be of little use or interest to the rest of you because it is not something that will be very duplicatable for general distribution, which is probably why I haven't gotten back to it--I am not neary ready for it on my GTS4 yet, but will probably try to incorporate it in that project before I get it ready for paint.

I put the intitial article about this project in one of the issues of The Shark Vibes that I was publishing as a News Letter for the 928 OC. I don't know if I could link that issue or the article here, but here are a couple of pictures of the project.

Jerry, very cool retractable spoiler.

Here you go, sans wiper. I will look into pulling a mold off this some day.

Ditto on the retractable spoiler.

Fixer, let us know when you're taking deposits .

Love the duck tail, loving the RS thread.

Thanks MJ928, I'm real excited about this Porsche more than any car in a long time. Will be lots to do (keep me busy) perfecting it

I will investigate the mold in the future and if not too difficult will make you one, you can finish it up yourself. Not interested in profit. I have no idea if too messy at this point. I am sure plastic wrap or similar could be used to protect the paint. It would make sense to try because if it gets damaged I'd have to start from scratch. -Matt

I think that one of the things that has held me back from trying to develop something to satisfy the apparent desire for some kind of "bikini" spoiler in the nature of what Matt, The Fixer, has put permanently on his hatch, is the need to figure out just how to mount it there without making it permanent as with Matt's, but so that it can be removed without leaving holes or other scars in the hatch.

Now, I think that if I were to do something like this, one way to do it will be to put short foreward extensions on each end, short enough to reach only the two mounting holes on each side of the hatch where the S4 and later wings are mounted. In addition, it may be feasible to also utilize the wiper holes in the hatch. which are going to be covered up, as other mounting points. And then, there might also be, or an alternate might be to put some kind of ears at the outer rear ends to clip over the outboard edges of the hatch to help hold it on.

Aside from that does anyone have any good ideas about how such a mini spoiler might be attached?

(In answer to this question it just occured to me to go out and look at how the center section of the spoiler is mounted on the hatch of my 80 Euro S that I have had sitting here for a while now.)

Also, I guess it has never become very clear to me just what the desire really is for such a spoiler. Some seem to want a replacement for the center section of the S spoiler system without the wiper void and others seem to want something like I described above that does away with the outer spoiler arches.

Now I suspect that those who would like something like this, but who are earlier than the S4, would not care for the foreward extensions that cover up the mounting holes for the wing, but rather something more like Matt's approach.

Since I don't really have a personal desire for one of these, if I develop one or more I would hope to be fulfilling someone else's desire. I suspect that is going to amount to about three or four versions of something without the wiper void.

Then there is the feature creap. Who is going to come up with the idea for putting a third (or fourth) brake lite along the upper rear of the spoiler? The need for that will double the versions of this idea. However, if I were to make it out of fiberglass, I suppose I could just make different versions of the rear part of the mold in order to have the ability to make one version either way.

Now, that is an idea. I guess I am rambling on with what seems to be coming into my brain about this. If I made these out of fiberglass the mold would likely be two pieces--one for the front and one for the rear. The rear could be two different molds and the front could also be two different molds all that could be put together is the configuration needed--with or without the stop lites and with or without the foreward extensions. Then there will have to be the same set of four mold components for the version that is intended to fill in wiper void in the S spoiler and mate up to the outer S spoiler extensions.

Enough!!!!
