Front suspension question

The XVMOTORSPORTS.COM unit seems to have the UCA mounted to a bracket connected to the crossmember and not to the shock tower. This would be much better than having handling forces travel through a component (shock tower) that was not designed for such forces. Torsion bar cars have those forces transferred through the bars to a crossmember underneath the front seats - very strong.

Those systems that do not have an arrangement like XVMOTORSPORTS would be okay to use if the shock towers were connected to a roll cage.
