I am replacing front brakes on my 2012 GTS. Porsche dealer tech friend of mine is telling me I need to also replace the aluminum locating pegs for the wheels that are mounted to the rotors. FCP Euro seems to be clueless about what these are? Any help would be appreciated.

Nope...Never heard of that, and I just redid all 4 calipers and replaced the front rotors.

they seem to be referring to centerlock wheels. When equipped, you get those 5 dome shaped studs that locate the wheel, while the center lock tightens it up. If you don't have centerlocks, disregard.

Christian Stark

Ahh! This makes total sense...

Doug H

Yes, centerlocks. I am just trying to score an aftermarket or cheaper set. Porsche dealership wants $500 for them, but I have a friend doing my brakes with everything going on.

When i did the rotors and brakes on the GTS I reused them. Might have been a mistake, but have seen no issues. Used a little loc tite when i reinstalled.

Don't waste your money. Fisher 7508 is correct. I used the same approach. Not a single problem. By the way, you do not need special/costly center lock rotors. Carrera S rotors are identical.

Remember to use the special paste on the center lock threads and make sure the spring loaded lock (inside the nut) returns to the full out position before putting the caps back on.

If you have the factory hub cap removing tool the end without the hook has the hex tool to coax the lock to the outer position. These tools are $9 at the dealer but they may have trouble finding it in the parts manual. Have them look it up in the GT3 tool section.

Wayne Smith

PS: Those center lock threads are sharp. As you spread the paste on them they will be happy to spill your blood. You won't realize it until you see the drips on the floor. Then you need to clean everything off and start again. Just saying ... Be careful.

There is definitely a recommended replacement interval for the CL nubs. If they're worn, they allow for rotational wheel play even with the mega torque of the CL nut.

Still don't know why the CL wheels are popular but if they're on your car, probably not worth the expense to change them, though I personally would. Removing and reinstalling a traditional 5 lug wheel using 2 guide pins as an aid is a piece of cake, and a set of Ti lug bolts is a lifetime purchase for half the cost of the replacement nubs with no special tools required.

Doug H

Yup, but centerlocks look cool and my total brake job will be less $1,000. I also like the looks of the RS Spyder wheels. The conversion plus the cost of new wheels that are decent vastly outweighs the extra $400 or $500 for these pins I may need to replace every 5 to 8 years.

I wonder if the replacement interval for the locating nubs on the center lock setup is based on the assumption that a GTS will see track time and a lot of wheel changes. I mean, that's why those cars have center lock wheels in the first place, right?

For a street driven GTS, I would think that the nubs would see a lot less wear and thus a much longer service life.

Here's more info on Centerlock wheels for street and track use including a rear hub recall and the recommended maintenance interval for some / all of the components if they'll be used on a track car - obviously a street car would need less service, but there's a statement in there about spirited street driving showing the same type of wear as track use. Dates would apply to all 997.2s as it runs from 2009-2013.

and here's a shop that offers a centerlock service with some nice photos of the worn out parts and why servicing them is required.

Just sharing info for you guys with CLs and asking about servicing and parts replacement for them.

Thanks for the info. The recall was back in 2013.

The recommended inspection period for GT3s was 4,200 miles of “track” usage and candidly, you need to inspect a lot more than your center locks before each and every track usage/weekend. This is super minor in comparison to everything you do for a car being tracked.

Porsche put these center locks on their most power cars and they are handling a whole lot of force for guys tunning their turbos and track guys. Although, I am sure the pins are totally fine on my now 40k street driven GTS cabriolet, I am totally down with changing the pins.

I was just curious why neither Suncoast nor FCP Euro stocked or recommended them for a brake job. Even the Suncoast parts guy was at a loss.

One of my Porsche tech buddies just texted me that I need to replace them. Strange no one else seems to know this or offer the parts.
