    Only the service for the central locking of the spiderwheels had to be made ​​today.

    What service is this for centre-locks? Smiley

    My GTS recently had it's first service (2 years).  No mention was made at the OPC about anything special for centre-locks...Smiley

    Got me worried now about hub failures and the like.  Someone sent me this video...

    Re: The downside of centre locking wheels..

    I had centre locks on my Morgan Aero 8 and it was a huge PITA to remove the wheels. I once had to visit a local truck garage to get them to unlock my back wheel with their heavy equipment. 

    I don't think they offer any benefits on a road car.


    Re: The downside of centre locking wheels..

    John - just get the wheels on-off by a Porsche dealer only - my car is a 2010 model and they have replaced some inner parts in the "recall" and increased the torque from 540 to 600 nm - I have spoken intesively with my dealer about it and he said it's safe - those must be old videos I haven't heard a new incident and there are many cars with center-lock now out...- I cannot believe that there are still problems with it....if then - only because people have changed their wheels by unqualified personel not having the right tools for it...

    Considering the fact that many GT3 drivers I know actually use non-official dealers for maintenance and repairs because they are cheaper, I wouldn't be surprised at all by this.

    Re: The downside of centre locking wheels..

    that is in fact very true !


    Re: The downside of centre locking wheels..

     

    I basically see 3 reasons, why CL have become so unpopular :
    1. There has been a fault in design with the center lock. Porsche has reacted with 2 recall campaigns.
    2. Changing the wheels requires a complex procedure with a high risk of doing it wrong. 
    3. Porsche has released a document with revised service/maintenance intervals. A lot of owners are now frightened because of the costs. They prefer bashing the center locking wheels and misleadingly praise the 5 lug systems but they ignore, that they better also follow maintenance intervals with their 5 lugs wheels. Wheel hubs and bearings etc become wearable items and need replacing when used on the race track.

    John H:

    In response Christian, that is all good advice..kiss

     I've contacted my dealer and the only thing they can think of is taking out tyre insurance, but it has to be done at the time of purchasing the car... Is that what you're referring to?

     

    I'm not impressed with Porsche Tyre Insurance at all - when I had a puncture they directed me to go to KwikFix tyres, a cheap repair outfit here in the UK, they could only supply N0 Bridgestone tyres not the N1 that the car was fitted with; when they saw the puncture they refused to replace it but ony plugged the tyre, citing that Porsche Insurance wouldn't pay to replace it. I purchased this insurance at a cost of £200 from Porsche Centre Swindon when I purchased the car, I plan to have a conversation with them when I return next month!

    When was the last time you saw a 5 lugs rear wheel broke off from the race track?

    The main disadvantage of CL is its potential catastrophic consequence on the track, not any of the reason that you mentioned above.

    I could care less about the money spent on extra maintenance schedule of CL if Porsche can guarantee 100% that absolutely no failure will occur.

    how many failure have you heard after the recall ?yes


    Re: The downside of centre locking wheels..

    I just purchased some 997.2 TPMS sensors for a new set of wheels and they ran me $119.00 each.

    The wife's 3series touring is on to 7 years with the original sensors still working fine....

    I have not heard any new ones since the latest recall, but it is winter time in most places now with no track events.

    The few incidents to me is already too much for the small numbers of GT3 out there.Smiley

    Early BMW tire pressure monitoring was not done via pressure sensors, but via wheel speed sensor. 

     


    Re: The downside of centre locking wheels..

    The 2007 E91 has TPMS sensors, look just like the ones on my 997.2.


    Re: The downside of centre locking wheels..

    RC:

    There are independent tire dealers who repair (!) punctured Z (Y) rated tires, which is in clear violation of the OEM specs. Such dealers can't be trusted. As far as I know, even V and W tires aren't allowed to be "repaired". One of course could argue that in speed limited countries, this may not be as important as in Germany for example but some excessive track racing with some high speed parts, could already be a serious problem.

    When we purchased our 997/2 we took out Porsche tyre insurance. We also had a slow puncture, caused by a nail, I phoned up Porsche Tyre Insurance who (incorrectly as it turned out) told me I could only take the car to the Porsche dealer that sold me the insurance. This dealer is 70 miles away when I expressed concern that I didn't want to drive that far on a damaged tyre but use my nearest Porsche dealer (20 miles drive) I was told no, the only option was to take the car to a local indpendent dealer Quickfix. I duly took the car there; they inspected the tyre and said it was repairable. I argued and insisted they rang Porsche Insurance who confirmed that they would not pay for a replacement tyre if it was repairable, so I went away with a repaired (plugged) rear tyre. I contacted the dealer from whom I purchased the insurance who were horrified and said it was totally against Porsche rules to repair any tyre. I eventually took the car back to them, a new tyre was fitted on the insurance. They asked for all the documentation (including the receipt from Quickfix) and was advised that this would be forwarded to Porsche GB for investigation.

    It was confirmed to me that I could have taken the car to any Porsche dealer of my choice in addition to replacing, rather than repairing the tyre.

    It goes to show that insurance companies appear to be totally dishonest and will do anything, even risk a driver's safety to save themselves a buck. Smiley

    Sorry, John,  did’nt see your post until now.

    But Börn is quite right with his answer.
    At my 2010 model was the central bolt torque increased to 600 nm, and the bolt thread changed. There was neither before nor after replacing any problems.

    Targa Tim:

    If you decide to keep the car for a while, just buy the tools.

     

    For the price of the tool (it is actually one), you can get two new tires. Not really worth it. 

    As to independent tire dealers: I stopped using them a long time ago for various reasons, especially since I switched to Porsche.

     

    Rc,

    much as i love you these comments are from inside the dealer bubble you live in.Smiley

    just try buying those two new tyres in wyoming  400 miles from a dealer if you dont have the cl tools to remove install the wheel. You must have the tools.  

    wheel enhancement is an independent in w la ive used  for  25 years, they have the cl tools.  I would  NEVER buy tyres from a dealer and get ripped blindSmiley

    your friend


    Re: The downside of centre locking wheels..

    Independent dealers love to tell stories (almost as "adventurous" as tuners) but I get your distance point (not having such an issue in Germany and the German automobile club is quite capable and fast if I need help and I cannot reach Porsche).
