Vey nice - love the key fob holder. Just as an fyi, that looks to be a TPMS valve, but Im not sure what type of climate you live in. I believe metal caps on TPMS valves in colder climates is no good.

I only stumbled upon this when I was trying to figure out why my after market wheels had regular stems with metal caps on the outside, and a TPMS valve with a plastic stem on the inner barrel. Turns out my TPMS valves required plastic caps only, so for aesthetic reasons they used two stems.
