As you can see many options that are not available on forza which we would all love to be able to do. Things like the painted roof and accents on the bumpers and side skirts, as well as the center lock caps. Would love to see these as options in the future though I highly doubt it.
I’d like to replicate this bad boy but i can’t 
There’s many more as well that we can’t make and the centerlock caps are always chrome.
