Update;
I just discovered a possible peace of mind on a few of you guys.
This picture is from the G37
You will need to remove the rear bracing tower shown in the bottom Red square
Edit ; The G37, 350z, G35 has the same setup. Only the 370z has the V-Brace which isn't absolutely needed . The G37 share the exact same setup as the 370z but does not include the V-brace and that big Tower for the brace found on the 370z.
then install the provided *blue* rear holding bracket
the 2 holding bolts goes into the already installed welded nut into the frame.
and
you will lose the 2 braces going to the front bolts of the sub-frame.
IMO they arent crucial to the rear stability since the 350z, G35 & G37 does not have it and have the same sub-frame setup.
