Impreza RS Coupe AWD F4-2.5L SOHC (1999)
4. Measure distance "L" between center line of loci of the axles.
Thrust angle: Less than 20° when "L" is equal to or less than 15 mm (0.59 inch).

Adjustment
1. Make thrust angle adjustments by turning toe-in adjusting bolts of rear suspension equally in the same direction.
NOTE: On FWD models, turn adjusting wheels one by one, by the some amount in the opposite direction of the adjusting bolts.
2. When one rear wheel is adjusted in a toe-in direction, adjust the other rear wheel equally in toe-out direction, in order to make thrust angle
adjustment.
3. When left and right adjusting bolts are turned incrementally by one graduation in the same direction, the thrust angle of the AWD model will
change approximately 10' ["L" is almost equal to 7.5 mm (0.295 inch)].
Thrust angle: 0° ± 20°
NOTE: Thrust angle refers to a mean value of left and right rear wheel toe angles in relation to vehicle body center line. Vehicle is driven
straight in the thrust angle direction while swinging in the oblique direction depending on the degree of the mean thrust angle.
Thrust angle: r
r = (a - B)/2
a: Right rear wheel toe angle
b: Left rear wheel toe angle
