Those M40s from the wheels boutique look exactly like the ones that i sold them from my 599. But id say go pinstripe, looks great, plus makes the wheel look bigger. If its just solid black the wheel almost gets hidden in the tire so to speak because there is no barrier between the 2.

 

I agree with the votes for no stripe - Sometimes stock is perfect.

 

Furthermore, the pinstripe detracts from the focus of the Ferrari - In such a vehicle, you really want to focus on the car, not the wheels, versus in something like a civic, where the car is standard and the wheels can really jazz it up
