Hi Simon,
No new findings yet. I am resonably happy with where it is now, but ideally if I could adjust it a little more that would be great. At some point I will replace the springs for slighly longer weaker ones which would improve the ride and allow me to adjust the car 8-10mm lower. I will take another look at Camber bolts to see if this is an option.
The origin of my car is unclear, I bought it from Pilgrim in 2002. It was part built, they had lost intreret in finishing it, it could have been built by Haldane and they got it with the company assets or it could have been an demonstrator build by Pilgrim. My tracking does not appear to have any adjustments except by adjusting the height for Camber or Toe for the front wheels.
