Suspension
Lumina Sedan and LS models feature a standard
4-wheel independent Soft-Ride Suspension that is
specially tuned to provide a comfortable ride, plus
responsive and predictable handling. The suspension
also is tuned to maximize the tight, solid body structure.
This 4-wheel independent suspension features:
•
32MM FRONT
AND 16MM REAR STABILIZER BAR to
reduce vehicle body lean while turning.
• MACPHERSON STRUTS HAVE SPECIALLY TUNED
DEFLECTED DISC SHOCK VALVING at all four
corners for a smooth ride.
• VARIABLE-RATE COIL SPRINGS help maintain
comfortable and smooth ride characteristics,even
with load variances.
For a more performance-oriented feel, Lumina LTZ
models feature a Ride and Handling Suspension as
standard equipment. To accommodate for high
performance driving, this suspension features:
• FOUR-STAGE FRONT STRUT VALVING allow a
fine degree of ride control over a wide range of
suspension movement.
• 34MM FRONT AND 20MM REAR STABILIZER BARS that
further reduce vehicle body lean while cornering.
Steering
For precise control in demanding driving conditions,
power-assisted rack-and-pinion steering is standard
on all Lumina models. This system features a 15.7:1
ratio for quick steering response.
Brakes
Lumina Sedan and LS models have front disc/rear
drum brakes with standard power assist. 4-wheel
disc brakes are standard on Lumina LTZ.
GM’s ABS VI 4-wheel antilock brake system is stan-
dard on LS and LTZ models and optional on Lumina
Sedan. Some things to keep in mind about ABS:
• ABS helps maintain steering control during severe
braking situations by reducing wheel lockup on
most slippery surfaces. All the driver has to do is
maintain pressure on the brake pedal and steer
the vehicle.
• ABS adjusts brake pressure by modulating the brakes
several times per second, a rate even most skilled
professional drivers cannot attain physically.
• The system modulates the brake-line pressure at
the wheels. Drivers should not “pump” the brakes
in emergency braking situations. Rather, they
should maintain constant pressure on the brake
pedal, allowing the system to work effectively.
