A lot of good info there. On my drag race suspension. Ladder bar with the traditonal perpendicular/behind the axel coil overs, your saying the rear springs play a much bigger part than I could of imagined.
The amount of seperation(anti-squat) is no more than .500-.750". I cant see how stored energy has anything to do with that. It is a function of leverage which I control by the rear shocks...I use the shocks also to control the compression(squat). Am I completely off base here?

Think about it this way.. The front stores energy by having a long light spring right? It works the same in the rear. Having compressed that spring X" you have that much preload in it. When you induce antisquat, it's going to put the energy of the highly compressed spring to the tire.

But one thing to consider is too much will do 2 things.

It will counter act some of the front raise. The front should start to come up before the rear does. But as the rear does, It's going to want to push some back on the front.

Secondly, if you have too much energ stored in the rear, as it slams the tires in to the ground, the tires might want to bounce back. This is where a double adjustable shock can help for sure. Loose for the seperation and tight for the compression.

Dave does a great job explaining it. I have his DVD and love it. I could watch it over and over. I always picks something new up on it.
