The newer ShoShop strut tower braces have a spherical bushing (at least it looks that way) connecting the bar to the cup:

The brace I have is an older design that has the bar welded to the cups, then has an adjuster in the middle of the bar (sorry no pic). Would the spherical bushings help reduce some of this stress on the strut bolt?
I really miss not having the ShoShop brace - it made noticeable improvements in handling, but I'm leary of putting it back on. I tried the OMP brace but sent it back; I didn't want to mangle myc AC line. From what I hear, the Sparco brace is a similar installation to the OMP. What do you think of this
brace from Freedom Design. Looks nice but I don't know how effective it would be and wonder how it installs.
