So, what is this Anti-Torque Arm
thing and why do we need it? When
we first started building the 3800 supercharged in our
GSX we also started building biceps. As we increased
the torque and HP output from the engine we gradually
started to notice every time we floored it we abruptly
headed for the passing lane because of the torque steer
from the front end. With our 3.4"
pulley and Cold Air Intake
Kit it wasn't too bad. With 309 HP at the wheels
it is beastly. (When we were experimenting with
our Nitrous-NOS
kit, things got really hairy!!) We needed something
to tame the beast. |

| Our first
design worked great!!! Unfortunately,
the front mounting point reduced ground clearance by 2".
This is bad enough for a car with stock ride height,
but on our lowered car we were constantly hitting even the
smallest bumps in the road. They worked well, but
were only suitable for use at the track. (When driving
at night a side benefit was the "4th of
July" style fireworks display guaranteed to generate
"oohs and aaahs" from other vehicles in the near
vicinity:-) |

We cured this with the design you see
here.
How do they
work? Your control arm bushings compress
and expand while under hard accleration. This deflection
in the bushings changes the angle of the control arm with
respect to the centerline of the car. These angle
changes act similar to steering inputs from the wheel.
Unfortunately this is very unpredictable and bothersome.
To eliminate this unwanted movement, our torque
arm triangulates the control arm. Our steel tubing
and spherical rod end design forms a solid link to the
subframe. This link can not change in length thereby very effectively stopping the unwanted control arm movement. |

What about
ground clearance?
Our new attachment points do not appreciably affect your
vehicle's ground clearance. The rear mounting point
has been moved rearward to the subframe and rotated 90
degrees. Ground clearance here is not affected at
all.
The use of clevis and hitch pins on both
the front and rear means the bars can be removed and installed
in seconds! |

 |
| Although the front mounting point does
reduce visual clearance, typically this does not pose
a problem. This attachment point is located very
close to the tire. Any obstruction which the tire
rolls over causes the control arm to deflect upward which
raises the torque bar as well. High mis-alignment
spherical rod ends allow the normal up/down movement of
the suspension components to function as intended..

The picture
tells more than words!
With the vehicle resting on the floor you can see how
little the ground clearance is affected. Compare
this photo to the pictures of the old design above. The improvements are obvious!
