Trianglelated "Monte Carlo Bars" are the race track proven and the 370s adoption of this is a wise move. I'm going attempt to make a Rigid steel one for my Z.
Strut tower bars don't do much except for the financial benefit of those that sell them. I had a Carbing strut tower bar, it's really not that rigid I was able to flex it by hand. The welded on end's are particularly week and I was able to bend them easily with hand tools.
