I've been holding off on ordering (thankfully!) but just ran my config again and red caliper covers are now required, whereas before you could un-select them. I prefer the look, will have to spend $200 to get the MGP covers in black.
Maybe ask your owner advisor if they can make an exception? It's just a flag on the car's options, so I don't think any P-features actually depend on the color of the calipers
