In addition, the
upper arms are at about a 45 degree angle from the direction
of the cornering load. Some binding in these arms is induced
during cornering as one arm enters into compression and
the other enters into tension.
Do NOT use
urethane in the upper arms to improve the side to side motion
of the axle. Because of the three dimensional movement of
the upper arms, severe binding will be induced as the suspension
moves--with or without a Panhard bar. This effect may not
be evident in a drag-only car, but if you plan to drive
the car on the street at all, we do not recommend urethane
in the upper arms (see the Rear Lower Control Arm section
for more information).
The Panhard
bar is a lateral suspension link between the rear axle and
the chassis, and is the best method to control the side
to side location of the axle relative to the chassis. The
Panhard bar is in a direct line with the cornering load,
and acts through spherical rod ends, therefore no bind is
induced during cornering. By nature of its design, a Panhard
bar does a better job of locating the axle than the Mustang’s
four-link suspension.
Maximum Motorsports' unique Panhard Bar:
- MM's Panhard
rod is the longest possible at 38" between pivot points.
This minimizes the amount of rear axle movement associated
with the arc of the rod's movement. The longer the rod,
the larger the radius. The larger the radius, the smaller
the sideways movement.
- Slots on
the MM chassis mount allow for vertical height adjustment
to keep the Panhard rod level at different vehicle ride
heights. A level bar reduces the effect of the rod's movement
arc.
