Static lcas are only going to firm up the rear and help with traction. When you lower the car it's good to pick up relocation brackets to recalibrate the geometry of the rear end which keeps the wheels planted when launching. Based on my understanding you want the lcas parallel with the ground for maximum traction which are what the brackets are for. I have a good bookmark to another forum on my computer that explains everything better and describes what is needed to properly lower mustangs. I can pm it to you later.

Thanks I'd appreciate it :) Or if you want to just post it here. I may not be the only one with that question.
