Looks great in black, titanium strip is definitely better looking. (in my opinion)
Those valve caps are pretty important on the TPMS equipped rims. They seal the stem from not only air leakage, but moisture getting into the TPMS itself and ruining it. Surprised to see a Ferrari without them. Sweet car though. That MC12 in the background looks nice too
Valve stem caps and Center caps are too different things...the center caps have no bearing on the TPMS. I'll bet the car was going to be tracked and as so must have the center caps removed.
Right Look at the rim picture, and at the brake picture. Both show the VALVE caps removed. See the threads? Yes, it's missing the center caps too, but it's the valve caps I'm concerned with. They are silver colored, same as the stem and have a small red rubber seal in the top of them that seats to the end of the valve stem and seals it off, similar to the rubber seal in a garden hose. You bet
