strut tower failure
#736
I see SP Motorsports has a proposed solution, but based on most people's comments in this thread, you all seem to feel the bracing/support must come from below to be effective?

There was a picture of the GT4CS with those brackets that still had a tower failure. The bracket did keep the strut from popping all the way through so it has that benefit.
Definitely doesn't hurt but I don't think it would totally prevent it.

I had extra flanges welded onto the motorsport plates & secured those to the chassis similar to the clubsport. With 3 extra securing points & the steel plate, I feel it's more resistant to failure. Even if it strut tower fails, at least the strut isn't going to come up & damage the hood as well. I'll post pics when I get the car out of storage.

This is also one case where I’d definitely recommend staying with stock suspension and not adding more hard mounts/ suspension components for obvious reasons

Also, if DSC, did impact occur under no, light, medium, or heavy braking.

I 2nd the pic request on this . Planning on installing my motorsport plates now that Spring is pretty much here. Looking forward to seeing what you had done .

This is a good application for 3D printing out of some high-performance materials. Could use an even more complex shape to increase stiffness...

I was thinking about something possibly similar to what you are saying. Here's my terrible cartoon, but I think you get the idea. The plate could be effective at preventing the failure if it could be stiff enough to x-fer some load into the thicker/stronger region where the extra bolt is located. Another way of saying it is if you attach the plate to its mounting location, it should press down on the 3 shock-mount locations and be stiff. Again, as has been acknowledged, this could be just moving the problem to a different location...
If you look very closely at the photos posted by SP Motorsports (specifically the top row, scroll right to second last photo). Notice the clubsport's plate on driver's side is different than the adjacent (R) streetcar's plate. The CS has two flanges mounting to the chasis & the yellow car has only one. The motorsport plates on the two cars are different. I had flange welded onto the driver's side flange similar to the CS's, so the plate is secured to the chassis in additional place. This may not prevent tower failure, as some CS's have blown these things as well, however it does make it structurally stronger & the strut won't become a "Jack in the box" if it does fail. Besides the CS is a race car, & I'm fairly sure the failures on them were secondary to more extreme impacts.

I dont think that anything short of an internal composite sleeve (tight fitting) bonded to the underside of the shock tower or a reinforcement collar welded to the top of the tower (under the top plate level) and then gusseted down to the frame rail will do the trick.
