Well, I just installed the UMI Performance rear shock tower brace part #3055... I like it, it fit perfect, and it makes sense. In the LSX El Camino my friend Greg is building, he has a completely different coil over shock set up and welded a cross bar to the frame where the shocks would normally mount and used his cross bar as the coil over upper mount point (very custom). I don't have that kind of room and my rear axle set up is not as custom as his... So, this UMI performance bar ties the frame together like his welded in coil over bar. I guess if a person really wanted to, they could weld this bar to the frame for additional rigidity - I won't be welding it though, simply because I like the bolt in application of this product.
This is really a no brainer for the the G-body... anything to stiffen the frame is good.
