Try as i might, I've tried to get my head round how offset is calculated and ended up confusing myself even more, I'm no mechanic so stick with me on this one. The problem is I have a 90 with lifted suspension on boost alloys (bought it like that) and the back of the tire rubs on the 'radius arm?' when full lock is applied I don't want to put wheel spacers on, but i'm pretty sure that offset wheels would eliminate the problem, I think that there is enough room under there to accept offset wheels since i plan to keep with 235/85R16 AT tires. Question is, what size offset will have a similar affect as 25-30mm spacers. Am I looking at somewhere close to ET08? :whoosh: Like i say, i think i've confused myself.
