actually, thinking more about it, you can easily match the tensile strength of the Cup bar with an aftermarket bolt on one. Porsche probably welded theirs to the body because look at the design, easy to manufacture. Two simple brakets welded to the body, one bar easily bent with 4 bolt holes. Much easier than all the machining and welding required with all the aftermarket bars.
Think it was built like that for strength.after market is like 10 to 8 bolts holding up the strut bar. The cup car strut bar is only 4 bolts attached to a welded mount.

Yea but those bolts should be tight, and the bar would be permanently deformed before it saw enough tensile load to lift the machined ends from the strut tower.
