Yes, I've already installed them on the car a few years back. Titanium lug nuts that is.
Titanium studs were too big for my application. As far as I know, no one company makes 1/2-20 drive studs in Titanium or else I would have had the first set. LOL.

Since this discussion is now so deep, I'll repost my titanium lugs. A company named Met-Tec sells them. Not much weight shaved, but some thing at least. That something is how I have arrived at this juncture and will continue till I reach the shed moment.
