Thanks TWOOD,
My Excalibur (CR knock off) has the Carerra coil overs in the front and they ride great. The back is very similar if not identical to the CR standard rear suspension except I think the shocks might be different. It rides hard back there, will axle hop a little in first and second and seems to have some lateral location slop in moderate to heavy cornering.
These are problems known in the mustang derived four link system. I think I read a post that said that the upper control arms are Ford parts, but it did not list any part numbers or application. If I could get that info, I might be able to fit some adjustable after market upper arms and fix the wheel hop with a little pinion angle adjustment. I think some better shocks will also help the ride and wheel hop as well. If I need better shocks or even different springs to get the ride better, the idea of coil overs is tempting and I get ride height adjustment as well.
The lateral slop I'm not sure how to cure other than urethane bushings with ear plugs and the accompanying buck board ride requiring a mouth guard. Not going there. I'd like to do a pannard bar, but have no info on doing this with the 8.8 in the CR chassis.
If anybody has any ideas how to upgrade the CR/Excalibur rear suspension to perform better with less harshness, let'er rip! If the FFR three link would bolt in without major surgery, I'd consider that.

Thanks,
Mike
