Off-Road Suspension Set-up

I was just wondering if anyone has any good suspension set-ups for an off-road vehicle, one where you can still drive around without the vehicle tipping but good enough to drive on bumpy terrain where it absorbs all the bumps and doesn't bounce around.

After playing about with it, here's what I've got for a D-Series:

 

As for the 3-link, there's not much to do to avoid flipping but I have my D-series set up with bump dampening very low and rebound damping very high. This gives you more of a trophy truck feel with a lot less bouncing. The 3-link rear is a great addition but a 4-link would be ideal for what you (and I) are after.

 

What do you recommend doing to make cars able to land jumps better? And what is the heaviest tire and rim combo for the 5 4 and 6 lug spindles?
