Back to my post #839 above. This issue really needs a sticky and a managed database (spreadsheet) with details of failures like the 3rd gear failure thread. The 3rd gear issue is now an official Porsche recall. If the strut tower fractures were collected in an organized manner, it would benefit the Porsche owner community. As some posted earlier in this thread, they were concerned this was a fluke issue and if it were a sticky it would stain the reputation of the 981/991 GT cars. IMO, enough of these have occurred there should be some organized data with visibility, in a sticky thread. I would rather head toward understanding the cause so a solution or workaround can be developed.
Looking back through earlier posts in this thread, the first failure was on the left-hand side of the car: https://rennlist.com/forums/gt4/9483...l#post13756059

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?

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:

Negative camber setting might be good thing to add to your list.

That being said, we can only hope that they will manufacture this type of reinforcement for the front struts and then do a recall to install them. Let's fact it, they can afford it, and they can't afford not to, because sooner or later someone is going to sue the $hit out of them if they get hurt because of it.

I don't think I've seen an instance yet of a shock tower failure on the left side of the car. As has been observed, even the right hand drive cars are breaking on the right side of the car looking out the windshield, so that suggests the right hand drive cars are not a true mirror image build if the weakness is predominantly on the right side of the car. I'm very curious as to what differences there are if any in the suspension, hub, frame of the cars, from left side to right side.

I dont see see a lot of mods in the GT4 forum. Would be nice to have an active GT4 owner to help moderate the GT4 sub-forum/

I have no real financial or emotional interest in this matter but just want to thank everyone who contributed...this is the reason I love the Porsche community so much! I'm very sorry to those who have experienced this strut tower failure as that would be gut wrenching and frustrating in every single way.

Alex let me know if you want to add the database to this thread or start a new one. We can then create a sticky.
In the future you can make requests or report issues via the report button which is the euro warning sign located in the bottom left of a post. There are several mods that look at the GT4 forum but we will not see everything.

BTW, why aren't GT3's failing more? There have been a couple of cases, and they share the same part, but one would think they would suffer more failures, as there are way more GT3 made and certainly being tracked.

Because the bulk of them are parked being wiped with a diaper. You can't break something you aren't using.
Perhaps.
Maybe they are using them and just not breaking them but when I look around at the mileage they are sold with after 18 months I just don't see them being used all that much.

1. Not enough on track and not enough getting decent miles (garage queens)
2. Longer front travel. The 991 front end has room to accommodate the lift kit, maybe that also means they have longer shock travel or a different front setup.
3. Maybe slightly different weight distribution of the mid-engine 981 puts more force into the front end.

I've been wondering the same. My leading hypotheses are:
1. Not enough on track and not enough getting decent miles (garage queens)
2. Longer front travel. The 991 front end has room to accommodate the lift kit, maybe that also means they have longer shock travel or a different front setup.
3. Maybe slightly different weight distribution of the mid-engine 981 puts more force into the front end.
