Hi Todd,

The castor and camber angles are very precise in a gravity car. The
wheels are larger so any change in the angles makes a big difference.

I remember writing to a person before about these types of cars. See:
There is also an ackerman angle and toe-in to consider.

It might be possible to create adjustable spindles (or an adjustable
king pin post) to allow you to tweak the castor and camber angles.
An example is shown at:

I hope this information helps.
Best of luck,

At first I built in 5 degrees of negative caster (read it somewhere) I tried the cart and found it very twitchy and lots of oversteer at speed. So last night I cut off the spindle brackets and am waiting for new ones to show up and wondered what your thought might be for a setting?
