lose your rear sway bar for added flex (it doesn't make it too bad on the road. If you want to lift it I might still have Jeep grand cherokee.560 coils for it and i've also got spacers that might work for the rear. You can crank your t-bars to lift the font but be carefull not to go to the limit with this as you'll likely just strip em out or fuck your b-joints.
Pathfinders are sloid rigs with the exception of the IFS and the auto needing a cooler lke Jeremy already mentioned on your other thread. Loks like you've got a 5-speed though, so that's a non-issue.
