Guy on the 996 board says storing the car with the wheels hanging in the air will "ruin the suspension"...........

Asked for factual support of the arguement, none has been delivered......I ask the same question here......

Facts not opinion please.......any reason to worry about storing the car off its wheels for a couple of months? Heated storage, low humidity......if it matters....

It actually seems like it would be healthier for the tires...

When a car is stored with the suspension hanging, the shocks are extended, and the polished rod of the shock is exposed. If/when it starts to oxidize, it gets rougher. When the car is again driven the now rougher surface much more quicky wears out the seals on the shocks, and they then leak. That's one of the reasons I've heard of for not storing the car with the suspension hanging

When I first got my 928 and had it at a dealership's service department, the service manager asked me if I was planning to store the car winters. When I said yes, about the first thing he said was to not store it with the suspension hanging.

I've heard that if your suspension lets the shocks extend fully, it can be bad for the seals. The weight of the wheels and suspension pressing the piston against the seals can distort them and cause them to leak. I'd think manufacturers would put some sort of spacer in to prevent that, or maybe it's just BS.

I had a guy I know in San Diego tell me the same thing. Never store with the wheels suspended. Ruins the shocks and bushings. Antique cars are worse because it can change the leaf spring camber. He ought to know, he has a car collection with over 200 cars and all of them are on the ground. He did admit that he has a crew that takes care of them and they jack up each car every so often to rotate the tires so as not flat spot them or cause sidewall cracking. Makes sence, you rarely see cars jacked up on stands in museums.

I noticed on the 928 when the wheels are allowed to hang, the only thing that stops the travel is the strut. So I agree the seals and strut can be damaged.

I've heard that if you own a 996 and a 928, both with cross drilled rotors, you risk ruining your suspension by leaving the car in the air.

But only with cross drilled rotors.

What I d is raise the car on jack stands just enough so that the entire weght is not resting on the wheels, to minimise platspots, but at the same time the suspension is not holding up the wheels. About half way through the suspension travel works good for me.

OrionKhan

Yeah, but I heard that is only the 996 that gets the ruined suspension. The 928 is fine.

Gretch

I am crying, I am laughing so hard.......

Gretch

Well....that is ok then.........BTW, another reason to use holey rotors is to reduce the unsprung weight.............

Oh Im gonna catch hell from someone for that one........

How about putting jack stands under the ride height measuring points? Tires off ground, suspension not hanging.

OK so if "polished rod of the shock is exposed. If/when it starts to oxidize, it gets rougher. When the car is again driven the now rougher surface much more quicky wears out the seals on the shocks, and they then leak." THEN with weight on the suspension the rod is half exposed and is only half bad ??

If you're going to the trouble of hanging the suspension, I guess you wouldn't bother greasing the shock rods...

SharkSkin

Same effect as lifting by the jacking points... except you might damage something. It's not meant to be supported there.
