Hi all..

Anyone have come up with an alternative brake disc dust shield for the rear that fits?? I cant find any for the 928s so presume they are NLA..

I cant imagine that Im the only one with rotten ones on the rear!

In reality, they are actually snow/water shields, in the rear.
In the front, the same is true, but in some cases, Porsche also used the fronts to help direct cooling air to the rotors.

I have never seen a previous request about these shields, so I would guess that Mark A. at 928 International must have about a ton of them. If not, and if there was any significant interest, making some of these would be an interesting project to take on.

I could use some bigger one for the front, (Cayenne Rotors) with some consideration of air flow for cooling. Perhaps dust shields with air scoops at the rear. Just brain storming and I don't think interest would be all that high.

We sell them with regularity as they corrode and the mounting points break off

I wonder how much difference there is in them from model year to model year.

The S4 Style is available for ~70 $

If I were to replicate any of these I would do it in stainless steel in about 22 gauge (about .032in), and I would probably spot weld little doublers onto the mounting points. Any other change in the design would depend on what I find when I take one off of one of my cars to study.

I still have the Radical Custom 928 ('88 S4) up on stands and it still has the running gear under it at least out to the rotors. I think this weekend I'll take one of the rotors off the rear and then remove the dust shield to study. I have been sitting here thinking about how I might make the forming dies and have come up with a fairly abbreviated method that will reduce much of the machine work that I am sure will be needed. I would make the forming dies so that a pair of them would be formed at the same time and then cut out of the formed blank with my plasma cutter and then hand finished before spot welding onto them, if needed, the mounting hole doublers.

Then there is still the question about the differences in these by model year of the 928. My first thought was that it might be best to replicate the early version (if there is in fact a difference) since there are a lot more of them around, I think, and since they are the oldest ones with the highest likelihood for need. Then, since I don't have those as readily available to study and since I suspect that the later ones might be adaptable to the early cars, I will start with the S4 version that I mentioned above.

I am also most interested to see just how these might be made to incorporate some kind of air scoop, both front and rear, without making the forming process or die fabrication too complex.

If that could work out for a pair of the rear shields, and if there is enough interest, I could then do much the same for the fronts.

Any input and suggestions about this are welcome.

I got the left rear shield removed from my S4 and have been looking it over after cleaning it up a bit so my hands don't get so dirty from handling it. I have decided to put an air scoop on it at the botton front end. Then as I was trying to figure out how to form a left and right at the same time, it finally occurred to me that the shield is formed in the same shape for each side; it is just finished a little differently for the left and right sides. Now I am trying to figure out how to make a form that can be changed a little to form both the left and right shield. Then I find that it is made of aluminum rather than steel; but I may still try to make some out of stainless.
