I ended up getting a front strut bar from Terry "One of his old Maximal Performance Solid strut bars" It is very rigid! I had to make some adjustments to it as I was unable to close my hood all of the way. I tried standing on the bar to bend it out a little. Well all 200lbs of me did nothing and the bar barely flexed under my weight.
Remember that this is downward force applied to the center of the bar. When the strut it attached the force applied is inward from the strut towers. To test the rigidity I places a lump of lay on the bar and shut the hood. Reopened the hood and measured the size of the lump. This tells me the distance between the top of the strut bar and the underside of the hood. I then replaced the clay and took the car for a nice hard drive down some curvy country back-roads. When I got how and measure the clay block it was only 1/16" smaller then originally. So this tells me the strut bar only flexed 1/16th on an inch. I would say that it is pretty sturdy.
I am not a fan of round bar/tube as it flex's more that square tube/bar.
With Cianci's bar the main bar in offset forward or the center of the strut towers. This is so that when the struts do flex the bar will not bend horizontal toward the roof but rather flex toward the front of the car and maybe a little upward. Hence the need for the reinforcement bars attaching it to the firewall.
The problem I see with their design is that the strut towers only really flex under hard steering. With Cianci's bar if you take a hard left turn it is going to force the FL tower inward but their bar design is going to force the FR tower horizontal and forward which will throw off the caster and camber until the turn is completed.
With a standard strut bar like the Maximal Performance bar, it will only throw off the camber slightly as the bar only flexes horizontally.
My info is really based off of 3D physics so I may be missing a few things,
Or be completely off my bonkers.....
