the question is HOW LOW DO YOU WANT TO GO? for a not to low but still kickass stance do a 2/4 with lowering coil springs if you want to do a disk brake conversion at the same time get the 2.5" drop spindles for a 2.5/4 drop if you want a real low one go for 4.5/6 thats with rear lowering coils and 2.5" front drop spindles and 2" lowering coils up front you will need a adjustable panhard bar and/or a c notch for this much drop... if you want LOW look into airbags...
