hi all.. i have 8x18 et35 wheels on a 2wd cos and am thinking of trying 9x18 but unsure on the offset.. if i stay et35 will the extra inch be spread evenly ie half inch extra inward and half inch outward or am i needing to change offset.. also does the lower the number mean the further outward ie et25 stick out further than et35 or have i got it the wrong way round... im sure their is room in the arch for an extra inch on the outer side of the rim towards the arch but the inner could get close to the rear arms..
thanks..
jay
