you should do this to restore the droop availalbe in the strut; either flip, or buy & fit spacers
you will then need some camber bolts
also you are advised to get a spacer for the top of the rear diff rose joint
these 3 mods make a real difference and finish what you have started off well
you might want to consider bump stop extensions dependant on what tyres you are using, to avoid rubbing in the rear arches; not so much a problem in the front
if your off roading doesnt involve much articulation then you could do without these 4 mods, but the car will drive better for them
