Those parts gotta be around here somewhere!

Hi Jerry,
The second tire cover arrived safely and thank you very much.
I would also like to order a set of liners for one of the 87 S4's.

Jerry Feather

Thanks, Gary, for the report and for your interest in the WW Liners. I have kind of known that when I got to the task of figuring out the last bracket for the pre-91 cars that is so far missing, there was likely to be a great deal of interest in these Liners for those cars.

I can at this point work sitting for quite a while and work on my feet for periods up to an hour before my back gets too tired. I think I will try to put some time in on the last bracket for the upper rear of the right Liner and if I come up with something for it I'll be posting either here or I'll start a new thread for these Liners for the 87 to 90 S4.

There is still a need to devise something for the bottom rear of the liners for the 78 to 86 cars since the rear of the wheel well is different with those and there is no place to hang the brackets at the bottom that the later cars have. With the later cars there is an angle brace that goes from the bottom corner of the quarter panel to the bottom of the front of the rear bumper cover which extends to the wheel well. Not so with the early cars; and there needs to be something there to fasten to.

Boy, ain't that the truth.

I have interest in a pair of rear fender liners with the foam sound insulation similar yo the OEM.
By the way, how are yours different from what Porsche installed as new on my 1991 GT?
What was Porsche selling them for? What years had them? just 91 -95?

The factory provided two different sets of them. One set was made to fit the narrower 91 and a slightly wider set for the 92 thru 95 GTS cars. At some point later I think someone saw that they had two sets of forms or molds, or whatever they made them with, and forgot or couldn't readily tell that they were two different sets, and decided that they only needed to keep one set, so the destroyed two of the molds. The problem was that they destroyed the left one for the GTS and the right one for the 91s. Then they continued to provide the mismatched pair marked as GTS Liners.

When that became apparent, and guys were complaining about the left Liner that did not fit the wider wheel well, and the poor quality of the material the factory put into theirs, is kind of when I decided to devise my own version of these liners. My effort was not to duplicate or even replicate the factory liners but rather to design something that I could make that is better than the originals.

My Liners are made out of fairly rigid ABS plastic and the upper portions are covered with sound deadening mass loaded vinyl separated from the liners with a layer of closed cell foam. I don't have any way of testing mine, but the reports from the field indicate that the noise protection is about equal to the originals.

My WW Liners do not mount directly to the factory mounting points but rather indirectly with a set of mounting brackets that I have to fabricate for the purpose. Once mounted they are very rigid. Mine are also in two pieces so that they are much easier to put in or take out once they have been originally installed. The initial installation takes me 3 to 4 hours to complete, and I think at least as much time for them to be installed in the field by someone else, with my written instructions.

I have two different forms so that I can form them for the wide or narrow rear quarters, including the 91s, both S4 and GT, which have the later mounting points in the tops of the wheel wells. My liners will also fit the earlier cars back thru 87, except that I have not yet devised a mounting bracket for the upper rear of the right liner since there is almost nothing in the car to mount it to without drilling holes in the car.

Then I have in mind (still) to figure out how to mount these in any of the earlier cars; but that too may take a whole different set of mounting brackets. I haven't looked into that yet.

My liners for the 91 to 95 cars are $900 per set plus S&H of about $75 domestically. I have also offered to install a set of these for $250 if that could be done here or within a reasonable driving distance.

I tried to order WW liners from Porsche in Germany a few weeks ago and the reply was "nicht lieferbar" (not available). They did not say anything about delivery time for the next batch to be in stock.

I have two sets of these Rear WW liners in progress, and need to get back to them to finish up. I have the various components spread out across the shop and have a shortage of the MLV for sound deadening, so have to order some more of that. Then, I took another opportunity to try to figure out where to mount the right upper rear of these liners in the pre 91 928s.

I had been kind of thinking about using the fuel line mounting points, but wasn't sure about how that might work out. Then today I looked at them again and find that there are actually three of them in the S4 and I also find that they are based on a stud welded to the body inside the WW. With the fuel lines temporarily lowered I think I can fab a mount to slip under at least two of these points and work outward to my liners with some material to mount to. I'm going to try that tomorrow. That will open up this project for at least the 87 to 90 cars; but more importantly it will get me back on track with this project to meet the needs of the few guys who I think are waiting for both these and the GTS ones.

If I get something worked out tomorrow I'll post a progress report. In the meantime, thanks to the guys who have been way more than patient waiting for me to get my **** back together on these.

I still say..that rivnuts and posts, and you can make your own mounts, where you want them. Why limit yourself to the limited choices available?

SO much effort on custom mounts, etc, and still not done.

Jerry Feather

What's your point, Jeff.

Since you seem to be so far out ahead of me on this I am real curious to see what the rear wheel well liners look like that you have developed for the early S4s.

glad to hear you have some time to pick this back up. I'm anxiously awaiting them for the GTS ☺️

This doesn't look like much progress, but of the three mounting points I think I will try to attach to the rear two. The other one is about a foot forward of the one in the top and also in the top. It would be easiest to attach to the two in the top, but together they are a bit forward of where I want the mounting to be. Using the aft two is a bit more complex, but if I can design a bracket that is not too complicated I think it will work better.

After mounting two pieces of ABS plastic to the two chosen points, as shown, next I need to finish out the inward half of one of the liners, probably using one that was made in the development stages, then I can put it in place and develop the bracket. Otherwise it is very much a guessing game as to where out in the open air the bracket will need to be.

So, I spent some time working on some of the liners I have had formed and in progress for too long and an additional piece for this bracket project. Then, I ran out of ABS glue and can't find my MEK to make some more. Off to the hardware store.

You miss the point.

I'm not ahead of you in fact 8yrs later, you're far behind all on your own. You started this in 2009? I lost interest in a $1000 set of plastic liners. So I offered some input to work around the cost/effort of custom mounting HW, when you have a whole wheel well of sheet metal to create mounting points at will again.

I just don't know why you started with the smallest go-to-market car, and struggle so much trying to use the limited attachment points that already exist and not create your own.

The placement and length/depth of what you can do with rivnuts and stands solves much of this problem. I don't do production quality work, but I do how how to cut/shape/hang material that I need done on my race cars..or when I used to run cars.

It's just input to accept and consider, or chew back at people for...that's all.

Of course Speed Toys never really had a clue, because he cannot actually fabricate anything.

Where I am with this Liner project is that where I left it a long time ago was at the point of providing Liners for the 91 and later 928s, either S4. GT or GTS. I still have not developed the necessary mounting points for the right liner for the early cars. However, I might very well do that now.

There seems to me to be a renewed interest in my Liners since the ones that Roger stimulated from the Factory are both now no longer available and they never actually fit worth a damn.

I think I will bring this project back to reality and see what I can do with the early cars mounting point development..
