Alright trying to figure out what the offset on the 18x9 mm evo5's are. They came off of a lexus GS300. And they were on the rear. What would the offset be on these.

 

Ask the person that was using them.
And what's with the current fad of people trying to do staggered wheels on maximas? Just keep the same size all around, and rotate your tires. Also, you are going to understeer if you widen the rears.
