I don't recommend messing with your balanced setup by introducing staggered tires. More grip in the rear = understeer. Then you'll have to spend a bunch of time and testing to tune out the understeer via tire pressures, sway bars, springs, shocks, offsets etc.

305/30/19 square will be fine. Try playing with a wheel and tire calculator if you are worried.

Here is a known aggressive setup that works:
18x12 ET30 front and back + 30mm spacer in the front
335/30/18 Rival S tires

Based on this pioneer (Cornercarver). He got to his specs by comparing backspacing with the Z/28 wheels. Backspacing specs that JPSS perfected before the Z/28 came out:

I'm going to run 305/30/19 on 19x10 ET16 in the front. This is how it compares: https://www.rimsntires.com/specspro....inite:%20Front

I'm going to run 305/30/19 on 19x11 ET36 in the rear. This is how it compares:

FYI most 305/30-19 tires are recommended 10.5-11.5 wheel. putting them on a 10" is going to cup them a little and be the equivalent of running a narrower tire... best to have 11" in front and 11.5 in the rear
