Actually it is an optical illusion, I have a 2019 WBSP and my buddy has a 2019 Shaker regular body side by side they look dramatically different measuring them mine is less than a 1/4 inch higher measured in multiple locations. His car at the time had 10000 miles mine has 800.
I forgot to add where the illusion comes into play is the wheel gap, the added flares sit higher to fit the lager wheels and tires. that measurement was dramatically different by 3/4 of an inch.
