What does changing to different holes on the suspension top link do?

Recommended Posts

Project Terra Conqueror Evo is tip-toeing to completion, and for the first time on a buggy I have options for the position of the inboard top suspension link because I've installed the Top Force FRP suspension mountings. I currently have the rear set in the top centre hole which makes the top and bottom suspension arms parallel. There are two other holes, both lower, 1 inboard, 1 outboard. What is the effect of using one of these other holes? I can see it would lower the instant centre of the suspension, but not sure why this would be good?

Those three holes on each side of the damper stay allow you to change the roll center of the suspension.  By changing the roll center relative to the center of mass in the chassis, the chassis will roll more ore less in a turn.  This can be used as a tuning aid in both the front and rear of a vehicle to affect handling.

Section 2.3 (in the suspension category) of this site talks about roll center:  http://users.telenet.be/elvo/
