I definitely recommend the connectors for either application if you have a high performance set-up. The uni-body is very weak compared to its full frame counterparts. Honestly, when I would jack up the car before I added the connectors the doors would not close properly while still supported by the jack. Once I added the connectors the doors would close properly when supported by the same jack.

Be careful, too much torque without the additional support can cause seams to crack and the body to twist.
