    TT Rear Axle Noise

    Is anyone experiencing a mechanical noise coming from what I think is the rear axle shortly after start-up when the car is cold in 1st or 2nd gear – it sounds like the rear diff engaging after the car starts off (note I have the slip rear diff)? The car is relatively new (March 08) but it’s a persistent noise. As I have a Cabriolet I may be hearing it more loudly than in a Coupe - Thanks.

    Nope.  I sometimes hear my LSD knocking at slow speeds on full steering lock for some reason.

            Alex :

    Can you tell me the advantages and the disadvantages of the LSD ?

    How is the cargraphic powerkit with you ? is it faster than FVD(555hp) and 9ff (560hp) ?

     Thank you Smiley


    Re: TT Rear Axle Noise

    LSD is good for doing power slides   Some say it's a redundant system what with the 4wd but I would rather have it and not need it than need it and not have it.

    As for the CG powerkit, I cannot compare to other powerkits but I would say that RS-Tuning is the best in business at getting max torque out of powerkits.  Torque is what you feel in the seat of your pants upon acceleration so I care a lot more about that then BHP figures. 

    Also I would say that the best thing about the RS-Tuning kits is how smooth it makes the Turbos.  The car feels so much more like a normally aspirated engine and is much easier to control in corners without having an 'on/off' feel to the turbos.

    All in all I LOVE my CG powerkit - easily the best mod on the car (and I have some other pretty good ones!)

    I am now not convinced this is the LSD making the knocking noise.  I think it's coming from the drivers side wheel.  Others are seemingly having the same problem:

    997 TT, what a car/che'mmmmmaghena!!!

    Re: TT Rear Axle Noise

    The CG kits above 544 start getting very expensive. I have no doubt these kits will be amoungst the best powerkits on the planet though. Personally I can barely use the power that I have now on the public streets. So more power would be of no use to me unless I started tracking my car a LOT.
