Shock tower failure on 718 Spyder

Again, you’re assuming massive impacts. Any impact that isn’t strong enough to completely shatter a wheel and smack the nose of the car on the ground should not tear out a shock tower. As you say, yes, it should take a massive impact. And how many 718 Spyders are on the road today? Probably 200, and there’s a report of one failure. If Porsche didn’t strengthen the towers, then yes, I believe they are very stupid.

991.1 GT3 engine fires were the result of con rod bolt failures and PAG quickly stopped production and sales. After investigation all the cars sold had engines replaced (roughly 800 iirc) and owners were compensated for loss of use. The finger follower issue emerged later and while it took some time, PAG acknowledged the problem and extended the engine warranty. Although disappointing to have such issues I think Porsche handled the 991.1 GT3 engine problems reasonably. M96 engine issues is a different story.
On the 718GT4 CS, there is a metal plate on the shock tower which is bolted via a rod to the front bulkhead and also bolted to an extension tube of the roll cage.

The SPMS Racing strut tower brace?? While it won't prevent the strut tower from cracking/breaking it seems, gotta think that if it prevents the tower from shooting up through the hood, that it more than pays for itself?? $495 for a set.
What's a new/repaired hood going to cost?? More than that I would guess? Anyone have these installed? https://www.spmsracing.com/2015-2016...rt-bracket-kit

Ten was my high guess, which would be a failure rate of .4%. Pretty small for a car that gets routinely thrashed on the track. And everyone I read about was due to a track off or hitting curbing, so you can't even call those 'failures'.
And this isn't a Camry. It's a high performance sports car, with stiff suspension, where light weight is at a premium. It's not going to be as durable to impact as a Camry or a Ram truck. It is not designed to take massive impacts and be able to dissipate force like a car with softer suspension.

I do not buy the excuse that this type of failure is acceptable because it is a high performance vehicle, those two are not mutually exclusive. There are plenty of cars (including Porsches) that handle well and do not shatter over potholes.
In the suspension, the strut tower is the worst possible component that could fail. It is difficult to fix, expensive to repair and cannot be replaced with a more durable part. If it was anything else it wouldn’t be as big of a deal as the wheel, control arm, anti-roll bar, shock, spring, etc. are serviceable in a home garage with basic tools & knowledge and can be upgraded with a different part.
I wouldn’t let this get in the way of buying the car if I really wanted it but it would be on my mind and I’d be extra cautious about road quality, bumps, berms, etc.

It's a bizarre post. Apparently its the rear and not the front.

Not sure it's a worthy plus for the 4.0. The issue isn't as common as the forums let on.

My point in the post was Porsche is not without issues. Their sh$t stinks sometimes too. Primarily aimed at halfmonkey for his knowledge as first time P owner.

There were several comments in German that were translated. Hard to follow. Supposedly happened while on the hwy while in 4th gear. He said that he did not hit a bump.
