Right... and that's my point about maintaining the % height difference front to rear. These cars come staggered and if you want to use the electronics to their fullest extent, you should keep them in their operating range.

You can always update the tire size in HP tuners!

Right, that's why I was going with those tires. But all the threads were related to ZLE's, so I was going off of that information, unless the ZL1 and the ZLE ECM's calibration for ABS is the same. The % difference is definitely a bit different than I was anticipating for the ZL1. 305/660/18 F 325/680/18 R is a 3% difference in height compared to stock's 1.9%. There really isn't a tire configuration that gets it closer. 305/660/18F 325/660/18R is a 0% difference. I was using Sport 1 towards the end of the season.

You honestly should be more than fine with that setup. If anything just be wary of rear brake temps if you're going to be in those modes.

Cool, that's what I thought.
