body rigidity - gone soft

Postby nbse2 » Sun Sep 23, 2012 9:40 pm

My NB used to be as taught as anything but over the last few months has been deteriorating and just getting worse and worse. Even though it does have a roll bar creating lateral stiffness something has given that is causing it to just shudder violently and even the seats are shuddering over moderate bumps. The car also does not seem balanced and gets unsettled very easily. The first thing that started to change was when I release the clutch the transition is not smooth and is quite sharp - not all the time. (the clutch seems fine) Anyone any ideas on this?? Is this something for a dedicated suspension specialist to look at, if so any one in Sydney that knows these cars? Would really appreciate some guidance on this. Regards

Wholesale Suspension @ Penrith or Spinning Wheels @ Alexandria or Heasmens @ Sydenham could diagnosis if its a bushing issue. I agree with the above, also how long ago was your last alignment?

the last wheel alignment was in January of this year. There have been a couple of track days in between.
