| MM Adjustable Rear Swaybar |
 |
|
Maximum Motorsports’ revolutionary
new adjustable rear swaybar for Mustangs is far superior to anything else
you’ve ever seen. When your goal is ultimate handling, you need the ability
to fine tune the balance of your car. Neither the Mustang’s stock rear swaybar
nor any other aftermarket swaybar gives you the tuning capabilities that
you’ll have with the MM Adjustable Rear Swaybar. |
| Maximum Motorsports’ rear swaybar
is more effective than the stock swaybar because of the way it attaches
to the axle and chassis. The stock swaybar mounts to the lower control arms
and has its effectiveness reduced by having to act through the control arm
bushings. The MM swaybar mounts to the axle and acts directly on the chassis
through end-links made of spherical rod-ends. Because of the mounting method,
and the shorter length of the bar, a smaller-diameter bar provides a wheel
rate similar to a stock swaybar (see chart). Wheel rate refers to the rate
of roll stiffness of the swaybar as measured at the wheel. Adjustments in
swaybar rate can be made by changing the position of the end links on the
arm of the swaybar. Moving the end links towards the bar effectively shortens
the swaybar arm, increasing the swaybar rate. |

|
A note of caution: one
of the factors influencing total wheel rate is suspension bind (restriction
of movement). The total wheel rate is the sum of the swaybar wheel rate,
the wheel rate of the springs, and the wheel rate of any suspension binding.
Potential binding of aftermarket control arms is something to take into
consideration when trying to tune your Mustang’s handling characteristics.
For more information on rear suspension geometry, see the section on Rear
Lower Control Arms. |
| Maximum Motorsports offers multiple
rear swaybar sizes to ensure that you will have a swaybar rate to suit your
needs. See the above chart for a comparison of stock swaybars to the range
of adjustment of the MM Swaybars. |
| 3/4” X .095” Wall Tubular Swaybar. This
bar provides a match to the stock 79-93 Mustang swaybar when set on full
stiff. In the full soft position, it is about 40% softer than the stock
early Mustang bar. This softer bar is recommended for people with other
companies’ rear control arms, which may be causing binding and unwanted
rear roll stiffness. This bar is also recommended for people with our control
arms, (or stock control arms), who want increased rear traction coming out
of corners in autocross or road race situations.
3/4” X .120” Wall Tubular Swaybar. This
bar will adjust to slightly softer than the stock 79-93 Mustang swaybar
when set on full soft. From this point the rate can be increased by 40%,
almost matching the 94-95 GT bar. This bar is recommended when oversteer
or wheel spin are not a problem, and you want increased control over body
roll in a neutral-handling car.

3/4” Solid Swaybar. In the middle of its
adjustment range, this bar matches the 1994 and newer Cobra bar. This bar
will adjust to slightly softer than the 1994 and newer GT bar. The bar will
then stiffen about 25% over the GT bar and about 20% above the Cobra bar.
This bar is recommended for cars when oversteer and wheelspin are not a
problem, and for drivers who wish to tune out an understeer problem in the
car. This bar is recommended only with stock lower control arms or MM’s
lower control arms. With this bar, stock upper arms should be used, or a
three link or torque-arm suspension.

1-1/4”
x .250” Wall Tubular Drag Race Swaybar. Designed for the
serious drag racer, this setup is intended to be less extreme in
stiffness than other race-only units. MM’s swaybar helps traction
by limiting body roll during launch. Bolts on and adjusts like our
other rear swaybars listed above.
