Was building an Italia Spider, came across a new optional "Carbon fibre rear bumper segment" that pretty much give it the old Challenge / Scuderia grill look. I always have this dilemma if I like the black grill, it is more sporty but less clean. Now is available on the 458, I can't wait to see the 458 Scuderia.

 

I think the entire back area is solid carbon fiber, not a cf grill.

 

yup, it is a piece of CF panel / trim piece.
