Just received my titanium lugs from WORLD motorsports and was shocked at how light they are! Very high quality product. When you pick one up its a weird feeling because you're expecting them to be a lot heavier than they are. Never thought I'd like lugs so much lol
When those were introduced I ask how strong they are compared to stock. I don't remember ever getting that answer. I don't like to be the skeptic, but I know how much power and speed you are dealing with. Please be careful, maybe get that answer for yourself if you haven't already.

Agree a matching locking nut would really finish the set off, although I could live without.
Regarding the strength, the website states they are stronger than stock bolts however, titanium is generally as strong as steel but with around half the weight overall. I really doubt these would be weaker than stock although I'm not entirely sure if they would be any stronger than OE...

That is somewhat reassuring. I remembered why I'm skeptical of these. Years ago I read in a motocross magazine of a racer switching back to steel axels for "reliability", that surprised me and stuck with me, as I've learned to trust dirt bike parts- even in other applications.
Titanium is available in all different grades and depending on the grade, the strength is widely varied. We make grade 2 titanium products which is a pure titanium and that is relatively soft and not as strong. We use grade 2 for medical screws such as attaching to bone. For automotive bolts nobody uses grade 2 titanium.
For the application described here we use grade 5 titanium which is very strong. It is an alloy that has aluminum and vanadium in it. The product ends up stronger that the steel bolts especially with the rolled threads and it is usually 40%-45% lighter than steel.
The most important thing to pay attention to when it comes to lug bolts is to make sure that you use the right type of seat for the wheel that you are mounting. This is the same regardless of what type of bolt you use. If you ever have any questions and want to make sure that you order the right bolt for your application you can always give us a call.
"Stronger than the steel bolts" is a little vague, but still very reassuring. The only thing left is metal fatigue and cracking resistance. How do they compare to OEM in this respect? I think it's called malleability, or ductile strength, something like that. Sorry for being such a skeptic, but it is relatively important. By the way I think your price is very reasonable.

It's called tensile strength-
Steel (API 5L X65) which is better than what the factory lug bolts are made from is- Yield (250 MPa) and Ultimate Strength (400 MPa).
Titanium Alloy (6% Al, 4% V) which is basically a grade 5 titanium is- Yield (830MPa) and Ultimate Strength of (900MPa).
Now can titanium be purchased that has different properties and different strengths? Of course it can, just like steel!!!!! The thing is, why would anyone want to use a grade like that to make automotive bolts????? We do use a different grade to make screws that are used as medical devices and are used to screw plates to bones and that grade is much softer but I wouldn't use that grade to make a part for my car. That is a pure titanium that does not have other metals in it.
If you have questions about titanium that concern you so much you should spend a little time learning about the metal for yourself. There are steels available that have a much higher strength than titanium.
If you want to compare titanium to steel then steel is much stronger than titanium but the thing is, Mercedes nor any other car manufacturer is using that type of steel because they don't need to.
