Every Porsche owner needs these
Never thought about actually purchasing salt and pepper shakers in my life ... until I saw these. I am waiting to put salt and pepper in them until I have the shop Xpel and ceramic coat them.

Installed a set of these: https://www.acerracing.com/collectio...14347910152227 I've had them on all my cars. I know it's a bit silly when it comes to weight savings even if rotational mass focused, but I feel compelled to do it to every car. BTW, the factory bolts look like cr@p for being about a year old!

can you share the weight difference?

Are these just as reliable as the steel bolts?

Cost doesn’t seem too bad considering the typical up charge for Ti.

Does not seem that they would look good with Black wheels.

About .75 lbs. Like I said, silly, but cool (in my head anyway...).
I know there was a "no" posted already, but I can only speak from my personal experience. I've used titanium bolts for well over 10+ years on over half a dozen cars, with at least a 1-2 track days a year and lots of weekend spirited canyon drives. I've never had an issue. With that said, I check them regularly given I probably remove all wheels at least once a quarter to clean rust and grime from the hubs and brake calipers. So when the wheels come off, I inspect them carefully and have never seen any signs of stretching and/or fatigue.
Ironically, as soon as burn through these pilot sport cup 2's, I plan on resetting with new black BBS FI R wheels. Also, do know that they will darken slightly over time. They are exceptionally "shiny" when new. They do offer a "darkened" version, but paying extra for that seemed even sillier to me than my already silly initial purchase.

The infamous "Aluminum Look" gas cap. An expensive piece of plastic, I know, but it does look good, especially with a black car. It gives you something to admire while you pump money out of your bank account.

I may be in the same boat as you. .75 X 4 corners is not too shabby. Add 2 lbs per Girodisk per corner and you are looking at almost 12 pounds of unsprung and rotating mass removed. Thats significant.
I won't go out of my way to get new brakes but when its time for brakes replacement I will surely be changing them.
Too bad I love the look of my factory wheels or I would be looking for some forged wheels as well
