Finally found some good data to support my observations regarding performance brakes -
"Stopping from 60 mph in 113 feet is fine but hardly spectacular. It's a few feet better than the rear-drive car thanks to an increased regenerative braking effect from the front motor. (Rear motors applying too much regenerative braking can destabilize the car, so they can't regenerate to their full potential.) The Performance model's big brakes and sticky tires haul it down in a far more impressive 99 feet."
This is from the motortrend review of the LR AWD, they have a bunch of other specs comparison between the 3 versions.

The difference they observed was 100 percent the sticky tires.
We know this for a fact because non-P owners have swapped to the same tires the P gets, without changing the brakes at all and gotten similar stopping distances to P cars.
We also know that because of how physics tells us the tires, not the brakes, actually stop the car, and that "performance" brakes can't actually reduce stopping distance on any vehicle that can already lock the brakes/engage ABS, which even the stock brakes on any production car in recent years can do.
The phrasing in that article was... poor....to put it politely.
