KMW, how does reducing the caster benefit turn in?
I know the XRay set-up book says that too, but I see it different. When we put camber on the car, we do it by adding kpi (king pin inclination). Kpi is the angle of the center of rotaion of the steering knuckle. The effect of increasing caster on a positive kpi set-up is to raise the outside wheel and lower the inside wheel when turned. This effect causes a weight transfer to the outside front wheel which naturally turns the car into the corner.
To see this effect, put the car on a tweek station and turn the wheels. Watch the bubble take off!!
This is the way I have always adjusted cars in the past (XXX-S, TC-3, etc.), and it worked. But I am interested in hearing how reducing caster will benefit, as both you and XRay say. Hey, they designed a great car, they must know what they are doing!!!!!
