ADJUSTING REAR TOE
Adjust rear toe using the 2 lower pivotballs in each rear upright; the pivotballs must be adjusted in
equal but opposite directions.
•
MORE rear toe-in (rear tires point in more):
Turn IN the forward lower pivotball, and
turn OUT the rearward lower pivotball equally
• LESS rear toe-in (rear tires point in less):
Turn OUT the forward lower pivotball, and turn
IN the rearward lower pivotball equally.
IMPORTANT:
Ensure you adjust the rear lower pivotballs in equal but opposite directions, or you
will change the rear camber setting.
ANTI-ROLL BARS
EFFECTS OF ANTI-ROLL BAR ADJUSTMENT
FRONT ANTI-ROLL BAR
The front anti-roll bar affects mainly off-power steering at corner entry.
REAR ANTI-ROLL BAR
The rear anti-roll bar affects mainly on-power steering and stability in
mid-corner and at corner exit.
Stiffer
• Decreases chassis roll.
• Decreases front grip (increases rear grip).
• Increases off-power steering at corner entry.
• Quicker steering response.
Softer
• Increases chassis roll.
• Increases front grip (decreases rear grip).
• Decreases off-power steering at corner entry.
• Slower steering response.
Stiffer
• Decreases chassis roll.
• Decreases rear grip (increases front grip).
• Increases on-power steering.
• Quicker steering response in high-speed chicanes.
Softer
• Increases chassis roll.
• Increases rear grip (decreases front grip).
• Decreases on-power steering.
TOE
Anti-roll bars are used to adjust the car’s side (lateral) grip. They can also be used in conjunction with a softer spring rate to handle bumpy tracks
more efficiently without excessive chassis roll at mid-corner. Anti-roll bars resist chassis roll and by doing so transfer wheel load from the inside
wheel to the outside wheel. The stiffer the anti-roll bar, the more load is transferred. However, as the outside wheel is not able to convert the extra
wheel load into extra grip, the sum of the grip of both wheels is actually reduced. This changes the balance of the car to the axle at the other end
of the car; increasing the stiffness of an anti-roll bar on one particular axle (front or rear) decreases the side grip of that axle and increases the side
grip of the axle at the other end of the car.
The overall traction of a car cannot be changed, but it can be balanced by distributing wheel loads. Anti-roll bars are a very useful tool to change
the balance of the car. Chassis stiffness plays a very important role in the effectiveness of anti-roll bars, and a stiffer chassis makes the car more
responsive to anti-roll bar changes.
ADJUSTING ANTI-ROLL BARS
ADJUSTING THE FRONT ANTI-ROLL BAR
•
SOFTEST front anti-roll bar:
Turn both blades so the fl at part is
horizontal
.
•
STIFFEST front anti-roll bar:
Turn both blades so the fl at part is
vertical
.
You may adjust the front anti-roll bar to anywhere between the softest and stiffest settings by altering
the angle as appropriate.
IMPORTANT:
Ensure that both blades of the front anti-roll bar are set equally.
