Torque Boxes? Do I need them

Does anybody have a pictures of what torque boxes look like? What I'm looking for in the pictures is before and after shot of installed Torque Boxes. Also should I (order first) install Torque Boxes before or after the Subframe connectors? The one I'm talking about (for both) are made by US Tool. This car is a Street/Strip but will see more Street. Car has built 340/727/8.75 with 3.23 SG(Clutch) and 3.91 SG(Clutch).Thanks in advance!
