Caliper clearance ?
 

Sup guys, currently thinking about picking up some different wheels for the z. I'm currently on stock suspension with intentions of installing eibach springs soon. Question is will they fit ? Will they clear calipers ? Will I rub ? Any help greatly appreciated.

Specs are: 18x9.5/18x11 +10 offset front and rear.
Tires: 255/35/18 front and 265/35/18 rear

Brake clearance depends on spoke design, not width/offset.

Post what wheels you're talking about and someone will better be able to help you.

You should also tell us what brakes you have: sport or base.
