Similar to the issues found on the Laferrari and 2012 E63 S where the brake calipers are fully unprintable - the Huracan Performante has a weird bug where only the large component of the rear brake caliper is paintable while the other is not. The smaller component is supposed to be black.
It is frankly a ridiculous looking bug and makes the car look ugly. Request to fix this issue as soon as possible.
