Apologies if I took your previous video post off track. Spent a fair amount of time doing just this with a scale often for what seemed very minor gains. At least swapping a heavier metal for ti is pretty straightforward like for like.

Previous post off track? What do you mean?

Posting a link to technical papers on and distracting conversation towards carbon reinforced aluminum. Quite obviously your part was 6 K carbon of good quality layup.

How do the Ti fasteners hold up and maintain set torque overall? Meaning, do they want to vibrate loose without loctite? Can you torque them down same as a steel bolt. I assume they are able to withstand more torque before they strip?
Any concerns with dissimilar metals?
They look cool, but for weight savings, seems insignificant. I’d be interested in how they hold up against corrosion over the years. Might be nice for suspension fasteners where the steel bolts are a bit more massive, brake caliper bolts, stuff like that that are on the unsprung weight side of the equation. I’ve seen they make Ti lug nuts, but I thought they were prone to galling. I do like Ti in general. It’s a cool material. I remember holding a large machine bolt for some piece of equipment we were installing and being amazed how light the bolt was. Truly amazing stuff.
Now it would be cool to see how much weight is in a car in just fasteners. Especially the bigger bolts and nuts.

To tell you the truth uncharted territory Day 1. Mostly the reason I put the Ti on non-structure components (besides the Strut Tower Brace, but the car can operate without that.)
The weight savings are def insignificant, but they are there. And yeah, stay away from Ti lug bolts . Seen a bunch of pics/videos of them shearing off at drag strips.

Ah no worries.
