You should check out the thread I just started about a week ago 'Cornfed Lift' if you search it'll come up.
I'm going with 3" cornfed spacers w/diff drop in front and OME891 and N86/N86C (not sure which yet) in the rear.
I've currently got Bils in the front so the ride comfort in the front will be questionable until I get it all put on.
Now I'm just throwing around idea for rubber.
