I've been reading about this and have looked into it a little. Also haven't read about an instance occurring on 997 chassis.

Perhaps the car got airborne at one point and bottomed out severely and no one is talking about it?

There's a huge thread on the GT4 section. It has also been reported on 991.1 GT3's as well. Some of the damage was caused by potholes or hitting the candies on the track.

The towers are cast alloy - ours aren't and will never have this problem.

sharkwerks says only on 981/991 gt cars not on 996 n 997

Cast aluminum seems like the wrong material for that part. The top of the tower takes an incredible beating, and often is hammered with incredible peak loads. Is there a history of steel strut towers bending or tearing that would lead Porsche to use aluminum--or is this a misguided attempt at saving weight? That's a part that just shouldn't go bad, at least not before other, more delicate parts break first.

I would also imagine that the kind of impact that would break the tower would also tend to blow out struts, bend the strut shaft and would very likely bend the hell out of a wheel. It would be a simple matter for Porsche to check those components to make sure this particular guy wasn't hooning when the tower broke.

There are lots of hints in the video that someone beat the hell out of that car--either him or whoever had it for 1500 miles before he got it. The fried clutch and the broken gearbox are damning. I'd love to know if those front wheels are original, or if the selling dealership replaced them before he bought the car.

I have personally had two clients with this failure, both on the same RF corner, both tracked lightly, ie not overly abused. Neither had even a bent wheel showing any signs of a harsh impact.
One was covered by Porsche under "customer satisfaction" The client promptly sold it. The other was told to pound sand due to Germany stating that their recall of failed parts showed "strut impact" as the cause.
​​​​​​Another client had the typical 3rd gest failure, followed up by a failed exhaust manifold the very next event. Again, not an abusive driver by any means.
I'm not overly impressed by these Carman based "GT" cars based on what we have seen, as much as I want to be. Again, these are facts, and not just an opinion based on internet rumors.
