Thanks for the replies.
I thought I'd post what I found out...

"The diagonal link is designed for racing applications only and works extremely well under those conditions"

"The diagonal link holds the rear end in the center of the car, allows up and down movement but no side to side movement."

"A diagonal link used on the street will fail, it's only a matter of time. The stress caused by the cornering of a street car puts too much bind and tension on the ends of the link and either the clevis or the rod end will fail, you just don't know when"

"For a street use vehicle a Panhard bar is tough to beat."
