SAI Steering Axis Inclination
SAI • The inward tilt at the top of the strut. • (looking from the front)
SAIand Included angle • Include angle = • SAI + pos. camber
SAI and Bump steer Zero SAI would = Major bump steer
Positive scrub radius RWD vehicles
Negative Scrub radius Used on Split diagonal braking systems
Effects of: • Larger tire • smaller tire • deep dish wheel
