Having all parts work as they are supposed to with OEM fit and finish is another story. Especially when you look below the surface. This beauty has it all including the performance and reliability.

We got this F8 sitting right with a set of Novelli Competizione lowering springs and spacers. Subtle changes that completely transform the stance.
