Has anyone converted 5 lug to center lock? Curious as to what the cost will be.

I looked into it, for fitting different wheels.
You would need to change hubs and rotors.
Possibly knuckle too (maybey, but can't remember for sure).

Do you have a rough idea of what it will cost to do?

I think wheels alone are close to $10,000 then you need to add the hubs. I bet you are looking at $15,000 - $17,000

Excluding wheels (because new wheels must be your motivation for doing this);

(4) Hubs: $1400
(4) Rotors: $1700 (originals sellable, if low miles)
(4) Center Lock Nuts: $900
(1) Center Lock tool: $300

I don't have online access to PET anymore to check on the other things like:
Spindles (if even needed)
Knuckles (if even needed)
Bearings (if even needed)
Misc Hardware (bolts, etc)

So its not a cheap upgrade, but not alarming, in the Porsche world (if no Knuckle swap needed).

Hopefully someone who has done it (or has access to PET) will chime in.
There were some early PET PDF floating around, but you need one that covers a 15 GTS.

If its just hubs and rotors then thats not too much .

Someone here might swap-worth a try. T

Other than look and cool factor, I see more cons than pros of having CL: Requires huge torque wrench, requires special wheels, and emergency tire removal are some of the issues of having CL. My GTS doesn't have CL and I'm very thankful of that.

Agree. CLs are a pain in the a... I have them on my GTS and GT3. It is my deepest wish that on the next GT3, 5 lug wheels will be an option. My GTS was a demo car so I had no choice.

IMHO, they are more trouble than they are worth. It took me 5 visits to tyre shops before I found one that knew how to fit CLs properly.

Yes CL is a pain when comes to finding an indy tire shop for servicing. I would guess about 90% of the indies can't do it. I bought myself an expensive and bulky portable torque wrench to carry for long trips out of the fear that no one can install my wheel in an emergency. It takes precious frunk space and barely fits.

Try America's Tires for servicing CL because some of them have the big torque wrench for servicing big commercial truck wheels. Even so you should be well versed in the proper installation of CL such as proper torque value and making sure the CL nut gear teeth pops out while reaching the proper torque to ensure safety. America's Tires' database indicated 368# for my 911 GTS and that is far from the 444# spec'd by the manual. Luckily the tech was willing to deviate with my instructions. It would be prudent to supply your own Castrol Optimoly paste to lube the nut because the shop probably will not have any. You need to watch the shop tech to make sure they did it right as they may not be familiar with the Porsche CL system. Simply torque to the spec is not enough. Remember you only have one bolt for that wheel! Lastly, once your tech does it right always try to get him again next time. I also tip him so I know he'll give it special attention.

The morale of this long winded post is that you need to know how to install CL correctly because you can't depend on others to do it unless it's a Porsche dealer or a Porsche indy shop.

With that being said, yes CL does look very cool and it is a lighter wheel with lower rotating weight that goes toward enhancing performance and feel.

Based on the replies looking cool is not worth it.

5 lug owners want CL. PDK owners want MT. When will the world admit I'm always right

We are a passionate bunch but make up a tiny percentage. Porsche has been putting CL's on cars for years--particularly their most expensive (Turbo, Turbo S, GTS, GT3, 918, etc).

You won't have any issues. All will be fine. I'm 10,000 miles in. Zero issues. Had a nail, local shop knew exactly how to handle CL. Porsche provides road side assistance & trip interruption if the worse happens. Forget carrying a giant wrench around. A fellow PCA'r drove from OC to Monterrey in his 918--where do you hide a giant wrench? There were, of course, no problems.

These CL's are not new, Porsche is not on the learning curve here....

The ONLY reason I could see not having such a great and iconic feature on your 911 is if you personally put on winter tires OR regularly track and need to switch wheels a lot.

I'm almost 40 and have never taking a wheel off anything. Meanwhile have a car that comes stock with a wheel that, for the first time, I don't day dream about modifying.....

Check this one...

pretty cool, but I can't believe he just wagged the torque when tightening, and then said it was race car technology. Really?
