4-link to 3-link

Alright so I was think the other day about the difference. What's the advantage of either? I know a 3-link provides greater flex off road, but not much beyond that. Also can we just remove the passenger upper control arm from are Cherokees and make them preform better?

I think this question fits better in the modified tech section. Try moving your question there.
