This is why forging produces such strong pieces. Working the metal increases its rigidity and strength initially, but over-working it will introduce too much fatigue, resulting in stress fractures or complete failure.
Yes, steel will improve through cold working to a point, but as you point out there are issues, including residual stresses.

I wonder if the lowering springs that some folks are using may be causing the suspension to bottom. That would put a lot of stress on the strut tops. The M7 strut brace seems to be a good preventative measure & stiffens up the car a bit too. Win, win.

In my opinion anything that causes a car to hit the bump stops is a bad thing especially when it comes to " mushrooming ". This includes lowered cars, 40 series tires , 18" wheels and 40 or 35 series tires and of course bad roads. The less the energy of a bump is absorbed the more of a chance you will deform the top of the shock tower.

I would add, run-flat tires to that list. As solid as they are, they really just transmit shock rather than absorb or soften it any.

Man you've got that right. I was going to wait & wear them out first. Now that I've read this thread I may change to a nice pneumatic tire sooner than later.
