Aluminum strut rods on the street?

Anyone use aluminum strut rods on the street? Mancini sells 'em, they look good. They are larger diameter than the steel ones but they claim they're lighter and stronger. I don't have a problem with steel ones, I just like the idea of lighter parts.

I am however a little uncertain about using these on a street/strip car, just not sure if they would be adequate for regular NY area driving.

Thanks for any input.
