Heya Dean, im not far from you but dont have any equipment to do the job. Im sure a tire place will drop them on for you, for a small fee. Try Cluse brothers @ Parafield The question you pose is also dependent on how low you are planning to lower (if at all?) Im running 18X8 et 38. So if you look at an offset calc: Mine as the control VS: 18X8.5 et 31 Inner Clearance: 1mm MORE(the inside of the wheel to the strut housing) Outer Position: EXTEND an extra 13mm (position of the outside edge of the wheel) 18X 9.5 et45 Inner Clearance: 26mm LESS(the inside of the wheel to the strut housing) Outer Position: EXTEND an extra 12mm(position of the outside edge of the wheel) I would think the front would have slight poke, around 5mm The rear flush (providing it doesnt hit the strut) may need guard work, or will need guard work if lower. Also depends on tire choice, ie stretched or gumby style. Check your specs here: http://www.rimsntires.com/specs.jsp http://www.1010tires.com/WheelOffsetCalculator.asp
