Drag Racing Suspension Tuning by using the Ladder Bar Percentage of Rise Method with how the Instant Center to Center of Gravity correlates! This will work for Ladder Bars and 4 Link rear drag race suspensions along with Anti Squat understanding. Don't get confused with Ladder Bar Anti Squat Line... rely on the ladder bar percentage of rise method for sure.

This video covers how to use the percentage of rise method to help determine the amount of hit on the rear slicks, especially with ladder bars for drag racing. While the Anti Squat method is a great tool and one I use often, I also like to evaluate the angles/slopes of the Instant Center intersection on the rise of the Center of Gravity. Trying to use the Anti Squat line for ladder bars will can get you confused. When you start to understand these two methods and the angles of the bars, now you have some amazing data from which to make educated decisions!
