Default Should I be concerned about this rust?

I'm curious what your thoughts are about the rust?
Each pic is from behind the rocker panel at each corner of the wheel.. rear wheel looking forward and front wheel looking back.

I wouldn't sweat it and slap some por on there

But I would certainly say those bushings are overdue

I plan on upgrading the suspension (along with poly bushings) this winter with some goodies from Elephant Racing.

Yikes. You've just been handed THE GOLDEN TICKET. You are now free of any guilt or criticism for anything you decide to do to this tub.

Salted roads is my guess. My car spent it's first 20 years in Ohio and my oil line brackets didn't look that corroded. Your car was used as intended....that's a good thing. Hopefully you got an appropriate discount.

Where is the car located? Almost looks like it's lived on a dirt road.

Fortunately rockers come off and you can easily address the problem.

Glad to see you going with Elephant. Chuck is a stand up guy.

.
Car is originally from New Jersey... so it doesn't surprise me to see that. I don't drive it in the winter and we get mostly sand put down if it should snow or ice here in the Midwest.
Nonetheless, for a NE car... it's held up pretty well.

Only reason I'm concerned about it now is from looking over some restoration threads and seeing something similar. Now I'm all concerned about rust. LOL!!

A friend of mine has a pristine black 993. The car is flawless.....or so I thought. It has the worst case of cancer I've seen. Right below the driver's side of the windshield is a gaping hole. It was at my house Saturday and reminded me of another friend's 964 with the same problem in the same spot. Perfect Guards Red paint....and this freakin' hole. ....so ya, don't be too worried about surface rust. Just remember to take care of it while you are in there.

I may have a similar hole. Noticed some water dripping inside that driver's side corner... I'm wondering if the windshield rubber molding needs to be replaced.
I can't see anything that denotes rust... but obviously water is getting in from somewhere.

I think cars that are a decade old and are daily drivers in wet climates suffer from water getting under the window rubber where it is out of sight and out of mind. You can't see it until it is too late. In other words change your rubber.

Get this for $20.
Brush it on.
It turns the rust black.
You'll feel great.

Amber Lamps nailed it. The window seals are a huge deal. All of them.

Pull your rear seat cushions out. and see if you have rust there.

Also check the seam where the rear shelf meets the body.

Some Examples:

I'm actually working on removing all of my carpeting to check rust that may have developed in corners.
I have noticed that I probably should start replacing the window and body seals along with any other weatherstripping.

Ok... I've taken off the side skirts to get a better looks at the rust.
It seems that the bottom of the rear quarter panel, extending to the back edge of the passenger door is severely rusted. I have attached 2 pics that show this rust.
What I need is an idea of how to repair this... cost, time, etc...



Looking directly at the rust.. it is underneath the paint and will collapse if just pushed on with finger.



This is looking at the rust from the rear tire looking forward.

If it's soft to the touch, it has to be cut out and a patch of new steel replaced and welded in.

Talk to your local Porsche club region and get a good idea of who does this on a professional level in your area. Someone who is familiar with Porsches and has a good track record.

And keep looking your car over, because if you have this rust around the wheels and rockers, there will be more of it elsewhere. In what you may think are the most peculiar of areas.

All good reasons to not use these cars as salt beaters unless you like dealing with this or passing it off on someone else.

(Sigh, we have become such a disposable society) I know a fair amount of guys leasing new 911s who know they will only have it a year or maybe two, so off it goes to do duty in the salt mines, stroking their egos all the while they are killing it softly. It makes sense from one perspective, but I don't adhere to that thought process and kind of believe all Porsches are special and deserve better....... flame away. Fire suits on. My winter beater is something other than Porsche and will never be a collectible; or at least not unless you think saving refrigerators and old microwaves is a must. Yeah, it's that kind of an 'appliance'..... just not ivory white or taupe.

BEST wishes with the remedy. It will be expensive by the time you are all done.

The Italians invented rust. The Germans perfected it.
