In respect of the caster blocks is the 10/12 degrees set in the caster block, so they give an extra 10/12 degrees caster, or are they set to give the 10/12 degrees caster overall, i.e. the caster built in works with the 501x kick up to give the final caster of 10/12 degrees?

If its set in the actual block, the 503 with 12 degrees kick up the final caster would be 22/24 degrees.

In recent pictures of the development cars, see Mark Rienhards cars at Reedy race, he was using the plastic caster block. Does the standard (plastic) caster block come with any built in caster or are they set at zero?
