LR Underslung vs Chain

I am curious of peoples thoughts on this. Which is better? Does it vary for conditions? If using a chain solid or w bushing/spring? On this thought to does it effect LF? In watching alot of different cars lately it seems the guys with chains are flatter, more controled. When just on underslung rock up and or carry LF.

A hard limiter at the underslung or a chain will give you the same thing if they are the same distance from the tire.

I would not use a spring loaded limiter because it may not compress consistently. Your ultimate drop would depend on the thrust generated by the lr tire.
