Did you try the aggressive camber set up on the 2018 ZL1 1LE with your R7's and the OEM 5thGen Z28 wheels?

See my post below on the size comparisons and the fitment onsets.
The Z/28 wheels are exactly the same fitment as the front ZL1 1LE, and only .5" more narrow on the rear, but you can still mount 325 Hoosiers on them. They work great.
To respond to the Camber questions, I simply used the Track Camber setting for -2.7 on the fronts and got great wear on the front Hoosiers. Very even wear. Actually perfect.
To respond to the Hoosier R7 tire size questions:
315/30/19 Front
325/30/19 Rear
At the Badger Bimmers Event @ RoadAmerica a couple weeks ago one of the instructors walked by and said "It should be illegal to put that much rubber under a car."
Loved it.....
This might help too.....below are pics showing the width of the Hoosier R7's mounted on the Z/28 wheels vs. the Goodyear 3R's mounted on the ZL1 1LE wheels.
The 315 Hoosiers are about 3/8" wider than the 305 Goodyears on the front.
The 325 Hoosiers are about 3/8" more narrow than the 325 Goodyears on the back.
Hope that all helps you guys with your wheel/tire/camber Q's.
I'm going back at it @ RoadAmerica this weekend.....if the weather forecast changes. Looks pretty wet right now.
