    Re: OFFICIAL: New 991.2 GT3 (2017)

    Hi Blueflame

    My OPC actually cleaned both the hubs and the centrelocks and regreased them, noise completely gone. They recently experienced the samw noise with a GT2RS so they immediately knew what to do. There are actually two threads on Rennlist too with owners reporting the same solution to that problem.

    I also have the Manthey settings with reduced camber compared to thir track focussed settings as I only use the car on the road. Steering feels felt only different by nuances.

    Do you happen to have the Manthey alignment specs (their track ones and/or the ones you use)?  Thanks

    I have the exact data on a printout in my car, will take a pic and share it with you.

    I have disassembled, greased, and rebuilt the centerlock bolt mechanisms on my car - it made a noticeable improvement in how they work.  This is a good idea every year or 2 (depending on how often you drive/track the car).  I have the factory Workshop manual pages, if anyone is interested...

    Edit:  Even if nobody is interested, here it is attached (don't grease the wide washer):

    Centre locks are a great example of technological regression.

    fully agree. They also come with their own service interval and - if I'm not mistaken - must be replaced after 6k track miles.  What bugs me is the mantra-like hassle of opening/closing the things on a track
