Ok guys hopefully some pictures will ignite answers. They arrived today and tyres go on tomorrow. Questions are 20" . 8.5" fronts +35 0FFSET. Should I run a 10mm spacer and will I need longer threads to do so? Rears are 10" wide +38 0ffset will have 275/35. How much low can I get overall and will the guards need rolling, neg camber etc
