Wheel Fitment 101: START HERE
You are asking for a solution without providing sufficient information
Give your current wheel specs and a picture so we can see the issue
Wheel fitment is affected by:
Ride height
Wheel width/offset
Tire size
Alignment
Rubbing is addressed by any of these things depending on your specific situation
I also assume you did not get adjustable front arms so you have no camber or caster adjustment
Using a massive spacer to clear brakes is suboptimal. It means you bought terrible knockoffs, which is what ESR wheels are
I suggest throwing your wheels away, reading up on fitment, and buying the right wheels
For reference, I am running 20x11 +15 in front with a 275 tire. The Z can handle AGGRESSIVE fitment...when some right.
