Ty- everthing Soko said. Small clarification in case you didn't know, when Soko says 1mm droop here is a picture: when you connect the center shock the pod should move "backward" no more than 1mm so that it looks like it is trying to form an "A". What this does is it gives the car some extra front grip by not trying to "pick up" the front tires off the ground on acceleration and it helps to keep the front end from "washing out" going into a corner which creates "push". Also, this adjustment helps to stabilize the rear. Many people don't set their "knives" up with this. thanks Sako for giving TY the info.
