Using this wheel stud stretch measuring fixture shown above, we checked the fastener stretch which stock, Ti, and carbon black Ti lug nuts. Fastener stretch is the same with all three lug nuts at stock torque value.

Like I mentioned, it's good for people to question things but at times you have to realize that with the caliber of a company like Katech they are not going to potentially risk the (well deserved) reputation of their company by selling low cost, substandard products especially something as trivial as a $6 lug nut!

Are you measuring stretch by checking the length of the stud before an after? How much stretch are you looking for? Just curious how much these things move under load.

Measuring stretch by checking the length before and after. We just want the stretch to equal the same amount as the stock lug nut.

Right, and is that .010'' of stretch? .050''? I would have no idea what's acceptable, but I hope it's closer to .010'' than .050''!

Under .002".

For question in #20, can use more than 1 season? And I know it "depends" on several factors.

Maybe I'll be the guinea pig and run some for 2 seasons.

How can I honestly answer that question without doing it?

Here is napa/china/whatever one that exceeded it's design life. As I torqued it, it did not feel right.

Looked fine before I put it on the stud.

So I just like to ask a lot of questions, is all, I'll put a set of yours on my c6z when I get it.

Thanks for your honest answers.

I think these should work fine & credit to Katech for not adding Vette tax.

Just got my ti lugs in today. Blows my mind how light they are, and overall quality looks great! Can't wait to throw them on.

I also had issues with crap quality lugs that almost screwed up my studs. I swap out wheels between my street and autocross set and hopefully these will hold up to the abuse.

Hey Jason, can you confirm the diameter of these lugs? The giant stock ones don't fit in the Forgestar F14s I have. I had to go get some gorilla lugs that would.

OD at the widest point is about .910".

I'm more interested in these for their tensile strength than weight savings.

bumping a sort of older thread - I don't know much about Ti lugs but curious if they hold up to numerous torquing cycles like steel. Anyone know? or do they need to be replaced season to season?

My son has been using these lug nuts on a 98 1LT Camero the past three years. This is a street/track car with ZO6 wheels. As such the wheels have been off/on multiple times.

I examined these nuts at VIR last month and they looked new.

As Werks posted earlier, if its a Kateck part it will be finest that can be bought.

Among other pieces, I just installed their carbon fiber roof and bow on my car. Its truly eye-popping. And the weave runs the same direction on both pieces.

That was my original question, I swap wheels 2x month min & I HAVE worn out the cheap steel ones, so unless they hold up at LEAST as good as steel, they would add up to be unnecessary expense.

Seems like Katech could easily test them to breaking point & let us know. Just gun them on/off 100 times (that's 50 wheel swaps street to race & back race to street). If they still measure torque good then I'd buy.

I'm not questioning the quality at all. I'm sure it's top notch. I'm more asking for a metalorgie perspective. Does Ti fatigue faster than steel in this application, if so how much faster? Do I get 10 torque cycles or 100?

Jason got back to me via email. He is looking into scientifically testing this, which is great. Really happy to see a company want to put some science behind their response. That being said, he has personally taken them on and off ~20 times and said he hasn't seen any issues. that's pretty good for me.
