To set the steering rack, I bought a Longacre Bump Steer gauge. I managed to get it set up even with my chassis up on trestles and it seemed to work pretty well. I managed to tweak the height of the rack to minimise the amount of bump steer. This will have to be re-done once the car is complete so it has been left in the ball park. I have attached a graph which interestingly shows how much the bump steer moves. Each line is a difference of 2mm height. I have left it where the line is closest to the horizontal.

Bump Steer
I have had a few weeks holiday in Cornwall and so have had little progress on the GD. Also with the good weather I have been working out in the garden doing all the things that need doing.
