Torque the U brace bolts to factory specs with the whiteline provided spacers.
Grease all metal to rubber contact, as specified in the instructions.
Use a flare nut crowfoot not a standard one, and I wouldn't use a wrench either - you'll start to round the bushing nuts when torquing them. I had 0 problems with a crowfoot and 2ft tq wrench while the front tires were sitting on ramps, about the only way you can torque it properly.
