That is completely incorrect, and I would be hesitant to work with any salesperson who did not know that. I have P17 with the Centerlocks.
By the way, unless you are planning to change wheels/tires yourself, the CL are no different than any other wheel. Don't let the naysayers (who typically either don't have them and are making an uninformed opinion, or are GT3 track junkies who have to change wheels all the time) give you the false impression that they are a bit of trouble. If you go to the Turbo forums you will not hear the CL whining that you hear here.

As an easy proof point, might you be willing to post a photo of your window sticker if you saved it showing the p17 and the CL wheels? Seems like one simple way to get to the facts.
Thanks in advance.

Thx for the response. Trying to get to the facts of what is and is not configurable is an oddly challenging task with Porsche. Seems like the on line configuration tool tends to be suspect with both quality and quantity of information. Porsche as a mfg company seems to keep their dealers less than perfectly informed....and then you have questions on what dealers tell you...frustrating.

btw...intention here is to use the window sticker as a proof point with the dealer to nudge them along in getting facts correct. If there are other GTS owners with center locks and the P17 sports suspension option that can help with a picture of their window sticker, please do.
Thx.

Agreed, the CL Spyders are pretty but they are heavy and the Porsche street CL mechanism is pain. Even if you dont ever do your own maintenance you are now limited to places that can handle your CL wheels.... basically your dealer. No more shopping around for good tire prices.

Interesting post I found.

Benefits of center-lock
1) Way faster.
2) Prolly slightly lighter
3) More area for brakes, if done right. You can shrink the mating surface for the wheel on the brake rotor slightly because of the smaller radius needed to affix the wheel. That means more brake surface area, or smaller/lighter brakes.
4) Probably technically stronger for the wheels (or lighter for the same strength) too. Dont have 5 stress raisers near the spokes.
Concerns with center lock
1) Way more torque to tighten
2) Often needs special tools to operate the special nuts
3) Low rim selection
4) Cost (due to low volumes)
5) Safety. one loose lug nut and you are #$%#ed.
6) Not as strong of a mate, probably technically speaking. If it can hold up to F1 car levels of force its obviously strong enough though.

...and that post is wrong.....CL's are not fast...faster to take or make the car faster...whatever.
zThey make no difference on fitting brakes and they are not stronger nor weaker than 5 lug wheels.

CL's are also not lighter. The CL design requires a much beefier center. All the load is centered on the CL instead of spread loaded over five different positions.
CL in the traditional style... or race style. Basically just a giant center nut to tighten. The Porsche street CL mechanism is not the same and includes a locking system that is a pain.

Much cheaper to go to 5 lug from CL's than the other way. Probably could do it cheap with used parts and then sell the CL's hubs for a profit.
