but i had 18x9.5 et15 and 18x10.5 et15 they fitted fine
JR do a 18x8.5 et15 so if that clears the front then your on to a winner

i need the nissan ones so i dont need an aligment as soonish as i can line them up again joys of a bit of paint, as the SPl have square cam washers i would have to take to a have proper alignment done and i haven't got the time
Im guessing japex is the one to answer if it can be done from not removing the subframe but the sub frame is aluminum so putting pressure the wrong way trying to remove or install the bush could twist it although Z1 do a tool so you dont have to remove the subframe which i have bought for changing the diff bushes when i get the time
