My Merlyn sports racer has the typical small formula car rear suspension
setup. It has twin parallel trailing arms, reversed lower A-arm, and upper
link. my question is what effect will castor of the suspension upright have
on handling?
You can measure the castor by putting a level on the outer part of the lower
A-arm. You can adjust it by changing the relative lengths of the trailing
arms. Any clue as to what positive or negative castor will do to the
handling? A setup guide for the Merlyn Mk11 suggest setting it to zero, but
why?
