I'm going to lower my 84Z 1 1/2" front and 1 1/4" rear. This is not going to be a drag car. It is being set-up for mountain road racing. When lowering the car how important are rear location brackets for the lower control arms??? Cocacolakidd.

 

They are important to prevent wheelhop. Do a search, someone made a nice post with all the physics behind it.
