coilover conversion

has anyone done this to the rear, b/c i am eventually going a few more inches of lift and am looking to ahieve about 11 inches. How will it ride with coilover rear and regular coils in the front. I will leave the front with a coil setup cause it works really well. Also where would i go about purchasing these parts and should i do a tri link or four link setup in the rear? Can anyone show pics?

What exactly are your intentions with 11" of lift?

It also sounds like you need a little more study time before building a rear suspension.

Rock Krawler make a 4 link rear coil over conversion for the XJ.
