Can someone explain how to lower the roll center on my leaf spring camaro? Thanks
It is half the distance between the bottom of the rearend housing and the top of the leaf.
3 inch lower blocks added to both sides would lower it 1.5 inches.
Yes, that is correct. Also don't use more than a 4 inch lowering block. It will create rollsteer and other problems.
Or...distance from ground to center of front bushing + ground to center of rear bushing /2.
Please correct if wrong.
Taller blocks will also make the leafs think they are softer...hence the increased roll steer...
I "think" the combination of heights, of the front and rear mounting points and the center of the rear-end is how the "moment center" is located...
Generally, the lower the roll center, the more side bite a leaf car will have...I think...:)
But, if the LR spring is stiffer than the RR, the car see's this and not our measurements.:confused:
on afco's web site (an circletrack to)its half the deference of front an rear mounting points,..like if the front is at 10 inches above floor an rear is at 20 inches above floor then moment center would be 15 inches above floor...if this makes any since! an roll center is based on how wide the leafs are mounted to rear end...Quote:
