i saw the same failure on a 991cab at the dealer last year. They said it hit a curb?

They must have big berms at Thunderhill....

Imagine the damage to the hood too, when that part let go?

I knew I remembered seeing something like this before on RL but it took a little searching to find again: https://rennlist.com/forums/gt4/9250...l#post13130190

Hummm, the blue car strut towers look different from the ^above white car strut towers.

I heard it was from dropping 2 wheels off at the exit of t6 and falling into a ditch. Thill needs to fill that ditch if it is true.

It doesn't look like the GT4 is a good choice for off road rally use now.

And how.

It's been a few years since I've been to Thill, but I was speaking with a pro racer 2-3 years ago who had an interesting viewpoint: It's still a great track in great condition, and generally a very safe place in terms of run-off—but he said rain has washed away a lot of dirt in some critical spots alongside the track, creating another kind of safety risk for roll-overs, etc. Perhaps this might be filed under "etc."

Be careful out there...

It may be cast steel, as it's welded to super high strength sheet steel.
I cringed when I saw this impact damage and realized that Porsche uses a casting, like the difference between a cast road wheel (GT4) and a forged one (GT3/RS), forged is stronger.

From this, it looks like both the front and rear upper strut mounts are aluminum. Wonder if the illustration is accurate.

I'll look at my car when I get home tonight. It might be bonded to the HS steel with adhesive. I don't remember looking at it closely to see if it was a weld or a bead of adhesive that was visible. There's a lot of adhesive used in these cars. Even the 918 has a bucket load of adhesive holding it together in places you wouldn't think it would be used.

I believe that illustration is accurate, and the dark blue is shown other places where I know the parts are cast aluminum, like certain parts of the inside structure of the doors.

After I stopped laughing, I remembered a story from about 1979 when my buddy's sweet young wife thought she would do a great thing and add some oil to their brand new Smokey and the Bandit 1978 Trans Am. She found the right opening in the top of the valve cover, kudos to her, but that's when things went wrong. She continued to add quarts of oil thinking she was supposed to see the oil level rise up to the opening in the valve cover, like you do when you check the oil in your old Briggs and Stratton lawn mower engine. After 7 quarts, she gave up, and tried to start the car to drive home. It didn't make it out of the parking lot of the convenience store. Had to have it towed to a shop to have some oil drained. It smoked, a lot. Made strange noises. All this was described by her, with a red face. Worth mentioning...she was super model beautiful . True story!

Yes, it's cast aluminum according to the diagram, I see that now.
I took a look and it's attached with some type of rivet to the sheet steel.
