Titanium lug bolts

Some people do, i dont. the weight they save is so inconsequential as to be not worth discussing. they are pointless with thr exception of looking nice. downside..i dont think pca allows them for track days

Downside besides cost is that they can come loose. It’s true for any lug bolt, but aftermarket bolts seem to be more prone to this than stock.

What I love about the 996 is its light weight. If any stock-looking mod could make it even lighter on it's feet, I'd be all in. In theory at least, reducing unsprung/rotating weight has a bigger impact on performance than reducing weight in other areas, but I'd still guess that the weight savings with titanium vs steel lug nuts isn't enough to make a difference in performance or driving feel. If anybody has ever felt a difference after using titanium lug nuts, it would be interesting to hear more about that.
For looks alone, there are always these:

While titanium lug nuts will shave some weight, remember that the lugs are close to the wheel center, so their rotational weight benefit is miniscule. Their total unsprung benefit is slightly better.
BUT........
....using a dissimilar metal leads to problems with galvanic corrosion and the bolts loosening up faster. Both of those things are bad.
On the street, or even a track day, with a mostly stock vehicle, you will NEVER see a benefit other than style points in the pits.
If you have a full blown, carbon fiber/unobtanium, full on race car that is on the grid at LeMans, THEN titanium lug bolts are a viable option.
But we ain't that.

Great point! The aluminum lug nuts on the old 911's were crazy light. I never stopped being amazed every time I picked them up. I guess the cars produce a lot more power now, but I wonder why they don't have bolts now that are closer in weight to those on the old 911s.

Everyone is using impact guns these days and over torque the lugs, I'd bet they get stripped real easy...

Anything new on Ti lug bolts? I did my front brakes today, and noticed the collars on one of the stock bolts is cracked.
I saw these on Pelican, look better than my original rusted ones.

I'm a little confused why these are labeled as 28mm long. Isn't stock 45mm?
I guess they are now PCA approved.
Or should I just get a new set of OEM bolts? Ti is like $70 more than a complete Genuine Porsche set. Since the Ti is unpainted, I'd never have to repaint them, which would be nice.

I never thought about this until reading this thread. Whenever I am changing out my wheels with CenterLocks I am always cursing Porsche. However, I think there is a benefit in rotational mass since all of the centerlock nut is in the center.

As others have said, not enough to make a measurable difference. The amount of gas in your tank will drastically outweigh (pun intended) the effect of lug bolt material. As will a minor change do your diet or exercise regimen! No need to spend money in this area. Stick with the proven, reliable, inexpensive product.

Just as an FYI the original 996 bolt design has been superseded the new 997 part has a dimple in the middle of the bolt head and the head is slightly shorter.
Sets of the original bolts are difficult to find as most suppliers will have an image of the original bolt then send you the new ones with the dimple.

If anyone is interested I have two sets for $300 shipped for each.
They were removed from my cars I sold. All my other cars use them. What people hypothetically are saying has never once happened to me. Being that they Have never became loose or stripped out. Nor have they ever had an opposing metal reaction.

Titanium is highly corrosion resistant.
