Caster Explained To understand caster you need to picture an imaginary line that runs from through the upper ball joint and extends through the lower ball joint. From the side view the imaginary line will tilt forward or backward. The tilting of this imaginary line is defined as caster. Caster is measured in degrees by
using a caster camber gauge. If the imaginary line described above tilts towards
the back of the car, at the top, then you will have positive caster. If the
imaginary line tilts forward then you would have negative caster. For oval track racing most racers run more positive caster on the right side tire than on the left. The caster split helps pull the car down into the turn, helps the car turn in the center and helps it stay hooked up on exit. How much caster should you run ? The amount and split depends on the type of car and track conditions. The details can be worked out by discussions with your car builder and thorough testing. Do you have any questions?
