I'm going to do a tall spindle swap, which involves buying an aftermarket upper control arm(or modifying the stock one) and swapping in a set of fullsize car/truck spindles. You can end up w/either a 11 or 12inch rotor and either a 5x4.75 or 5x5 lug pattern depending on which spindle/rotor set up you get.
I got my spindle/rotor set up off of a late 90's Impala/Caprice and have a 5x4.75 pattern. This gives you larger rotors plus pushes your tire/rim combo out about 3/4inch or so...Joe
