ANTI-ROLL BARS (available option)

Anti-roll bars are used to stabilize the car from excessive chassis roll, which
occurs when the car leans in the turns due to centrifugal force. Anti-roll
bars are generally used on smooth, high-traction tracks. If the conditions
are very bumpy, anti-roll bars may not be necessary.

If you are driving on a high traction
surface and the car is oversteering,
use the optional front anti-roll bar
kit (#30 2460). This decreases front
chassis roll and steering, giving
more rear traction.

Anti-roll bar adjustment is performed
with disconnected shocks.

1. First, be sure you have adjusted
the downstops equally on both
sides.

2. Place the car on the flat board
and disconnect the shocks.

3. Lift up the front right wheel very
slowly. When the front left wheel
starts to lift off the surface, note how
far the front right wheel has been
lifted.

4. Do the same thing on the other
side. Lift up the front left wheel very
slowly. When the front right wheel
starts to lift off the surface, note how
far the front left wheel has been
lifted.

5. When properly adjusted, both
wheels should start to move up at
the same lifted position of the other
wheel. If this is not the case, then
the anti-roll bar needs to be
adjusted.

6. Make sure the wire is not
tweaked. If it is, correct it by
carefully bending it straight.

7. If the wire is straight, try to
decrease or increase the height of
the pivot link on one of sides by
adjusting the distance of the pivot
balls. Adjust it little by little until
both wheels move up at the same
lifted distance.

Initial Setting:

Wheelbase:  6mm (2+4mm) in front
of arm, 3mm behind arm

When adjusting the wheelbase, you need to adjust the distance that the
adjustable ball protrudes from the rear bulkhead. 

••  SShhoorrtteerr  w

whheeeellbbaassee::  Extend ball further out of rear bulkhead

••  LLoonnggeerr  w

whheeeellbbaassee::  Push ball further into rear bulkhead.

Initial Setting:

Ball extends 10mm from rear bulkhead

To change the length of the adjustable balls, loosen the setscrew in the top
of the rear bulkhead, and slide the ball in or out according to the wheelbase
setting.

Make sure that the left and right settings match. For accuracy, use the depth
gauge of a caliper to measure the distance between the top of the ball and
the side of the bulkhead.

Use the following table as the guideline to calculate the wheelbase setting.
