The problem is real sadly. We know of 991gt3'S and and race cars that this has also happened to. For what it's worth I'm not going to modify any suspension stuff especially up front such as springs, mounts etc... you'd be playing with fire. The tolerenaces have already proven themselves to be insufficient;(

That blows the stiffer spring theory out.

My next project is to find good bump stop dimensions to balance protection and usable stroke at the front end.

I wouldn't go that far yet.

Are these failures ones that have already been reported on RL?

If not, were they more like Joe Weinstein's (public roads at highway speeds), or more like crash-impact failures such as off-track excursions that result in a big-time impact of some sort?

There are folks that are outside the USA and also that are not on rennlist. There has also been some chatter on the European forums too there's been chatter. Locally I wouldn't call using the burm correctly at a race track going "off" either. Stock tires, stock wheels etc... It does make me nervous for sure

okie981

No sir, absolutely not, using a berm is completely within normal use for a Porsche vehicle, and is not an "off", IMO. And I would also include very aggressive use of a berm to be within normal use for P-cars.

Not on the German forum, and that is probably the biggest P community around. Though I believe the % of people tracking their car is higher on Rennlist.

OK, added there for their comments.

Seen it... and commented on

Pff.de needs more popups..lol


I tried to have a look.

Joe Weinstein

An update for my case. PNA had it inspected, and the wheel is bent, so this is
seen as 'external influence', not a manufacturing defect, so I'm going the
insurance route. From what I hear, the chassis part is on backorder with
no ETA, and my body shop says that it may be a long process between
him and the insurance carrier before the full degree of coverage (or salvage!)
is decided...
Wish me luck.

Joe, that sucks! Ask them for a picture of the bent wheel. Don't accept that its just out of true the factory spec is .030" lateral and radial run-out. It needs to show significant damage . good luck carl

okie981

External influence. Hmmm. Cars experience external influences anytime they are moving, so this seems a bit ambiguous. Would like to see how significant that wheel damage is as 4Carl commented. If you don't recall anything that could have bent a wheel, maybe the car suffered a suspension whack before you took delivery?

Joe Weinstein

They said they took the wheel off, and took it to a balancer to verify if it was out of round, and it was, with a flat spot, and a bubble in the tire at the same place.
I guess I hit a shallow pothole or something.

Oh, and they mentioned I might have caused it by lowering the car (which I
did, to get the alignment I wanted, and it was still fine for driveway lips etc)

I'm sure my continuing concern will be the same as all yours, that this might
happen again.

stout

This should just not happen. Full stop. And it definitely should not happen to multiple cars. "May have been caused by lowering the car..." Uh...it's a GT car. Were you still inside the factory specs, or set lower than them? I've noticed my GT4, as delivered, seems a bit high—as in higher than some X73 cars I've seen.

Sorry to hear of your trouble, Joe. If this matter is left to insurance companies at $30,000 to $100,000 a pop, we will all pay for it via higher premiums.
