Was checking to see if anyone is running a similar set up, 245/40 on 40et set of 8s all the way around. I have a set of staggered factory 18s now but have a buddy selling these and think they should work just wasn't sure about them tracklineing with 245s on all four corners. Wondering how they would look compared to the stock setup I have.

My intuition says you should be fine, but I'd be very interested in hearing from someone with experience. Could you get 2 spacers for the rears, just to get them a little wider than the fronts?

That'll be wayyy sunken in

holy sunk..

What is the et on the staggered 18s from the factory?

The wheels will be sunken in about 1/2" more than the oem coupe 18x8's.

Keep the stock wheels you have.

I would like to but I'm redoing my suspension because every damn bushing is shot I looked at the pattern wear and one of the rear wheels is actually got a slight hop in it.

Lol sorry damn phone

don't do it if you are lowered man. im on the stock 18's and im begging for either some wheels or spacers cause i think my wheels look sunk in. but gl with ur decision

You can run 245/40s on 18" rims without any issues. By et are you're referring to the offset, if so 40 isn't good! Offsets for our Infinitis s/b at least in the mid 20s. Don't waste your $$ on wheels that don't fit and require spacers to work, that's never a good deal!

Offset for factory 18" is 30. 40 will work. Wheels drastically change the look of the car. I don't think this will be a good look, but it will work.
