strut tower failure
#903
I see more GT3's than GT4's, although it's possible that it varies from track to track. However, aren't there far more 991 GT3's produced than GT4's, since they weren't limited to one model year? If so, then even if there was a greater percentage of garage queens with the GT3 crowd, chances would be that the GT3 gets (ab)used as much as the GT4.
My guess was #3 also. #2 would be plausible if true, which I don't know if it is. I thought they both had the same front suspension.

To add a bit of info here...our tracks are probably worse than most in the conti USA....yesterday we had a track day. I was the only GT4 but at least 6 GT3/RS. Two of them are tracked pretty heavy (riding over curbs) and so far no failures. Owners are getting a bit nervous now as this thread is making a lot of people aware of the problem and came to our pit to talk about this. Of course we only have 1 track day per month so probably way less miles and time on track than stateside cars...BTW, after the hurricane our roads are also a mess so you can add that to the mix. Since there's no way of pointing to the cause of this we are keeping our finger crossed.....very bad from PAG for not addressing this issue as GT products are supposed to be designed to handle the abuse of a track..

This failure puts you in a very unfortunate insurance grey area. This is kind of a worst case scenario with this failure mode. Track insurance not covering it because it was not an collision, road insurance not covering it because it was on track, and Porsche not covering it because they have not covered any other yet and that would be an admission of design flaw.
Have you tried your road insurance? I seem like if road insurance have covered other failures reported here that either your road or track insurance should cover it. You might have to lawyer up at some point. With the repair costs noted on RL, it is enough to warrant legal action IMHO...

Long term, I don't think they can ignore this issue. This is only going to get worse with cars ageing and being (ab)used more. They need to look at the long term effect and manufacture an insert and recall all GT4's and maybe GT3's.

Here are some detailed photos of a tower failure due to an on track crash. I don't know the crash details but this was a fully stripped down 981 car with a cage so I'm sure this was due to a racing incident. There was a ton of other body damage to the chassis that I didn't document.
All of the normal accessories that block the view of the tower structure have been stripped out.
Hopefully this will help the engineers on here further analyze the cause and potential solutions for this issue.

Thank you sir, I think this can only help in the long run. It truly sucks this is something we have to deal with as 981/991 car owners. I don't want to be Debbie Downer, but as the miles pile up over the next few years, we may find the non-GT cars start seeing this failure mode, so just because one doesn't own a GT car, one may benefit from the gathering of this information. I'm confident there are Porsche engineers and managers lurking on Rennlist. Hopefully sometime in the next few years a recall will bring in cars for installation of a reinforcement cup inside the front shock towers. I think the safety concerns will push this at a corporate level at Porsche. Of course there are all those examples of Porsche design issues that never got recalls (IMS, coolant lines, etc.)......

My car has not had strut tower issues, but this is certainly a concern. I would be happy to start a spread sheet to document the issue. I'll start a separate thread, but would like suggestions about what info should be included. My initial thoughts are:
Date of failure
Date of vehicle manufacture
History of track use (# days)
Suspension modification (yes/no, if yes -what mods)
Wheels (stock or aftermarket, 20" vs 19)
Side of failure: Driver/passenger/both
Mode of failure: Pothole, curbing, hard braking, etc
Repaired via track insurance, regular insurance, out of pocket
What else?

Not something that you'd expect to see in a GT car.
