For Ferrari we have 2 styles of titanium lug bolt options, the difference being the head design. The standard head design which uses a 22mm wrench and the more aggressive looking 17mm internal hex head design. Both are M14x1.5 with a 77mm shaft. If unsure please simply remove your lug bolt and send us a photo to email@example.com
We do offer black titanium lug bolts on a custom order basis. We use a Physical Vapor Deposition (PVD) process which is much better and more durable than simply anodizing titanium. PVD is a complex process which vaporizes a number of metals and then binds them on the surface in layers in a heated vacuum. This is the same process used on the beautiful black finish of high end black luxury watches such as Rolex and Panerai watches. We are always asked if the natural titanium finish will look good against a darker wheel and our answer is yes. Natural titanium pops very nicely against a dark wheel and you will be showing off the beautiful titanium you paid for so it would make sense to go natural but many customers still prefer a black titanium so we offer the best solution with the PVD Black Titanium finish.
We do not offer lock bolts for this application as they ruin the clean aesthetics of a symmetrical and consistent lug bolt design. If your car came with lock bolts you can always use the same lock bolts too.
