NOTE ORIENTATION
The RX8 kit comes with both types of front anti-roll bars; blade-style or wire. Decide which anti-roll bar to use.
Pre-thread mount with the set-screw
After anti-roll bar is inserted, install and
tighten the set-screw
Blade parts may have been installed
earlier, see page 24.
ALTERNATIVE 1
(BLADE ANTI-ROLL BAR)
is recommended for long, fast tracks when maximum cornering speed is needed. With the blade anti-roll bar, the car will not dive in the corners and will
maintain maximum speed. Follow the “Alternative 1“ assembly steps (immediately below).
is recommended for smaller, technical tracks when fast direction changes and side weight changes are needed. Follow the “Alternative 2“
assembly steps starting on page 28; DO NOT assemble the blade bars as described immediately below.

HUDY GRAPHITE GREASE #106210
It is extremely important that the arms move freely on the
pivot pins. If they do not, use the #107634 HUDY Arm
Reamer to slightly resize the holes in the arms.

Ensure that the suspension arms move freely. Ensure that the eccentric holders move freely.
When the bar is set, verify that both sides move at the same time. If they do, the bars are set up correctly.
If not, make sure that both downstops are the same. If the arms still do not move at the same time, gently
loosen the screw which holds eccentric bushing and adjust the bushing until both arms move at the same time.
The position of the front arm directly influences the steering
Ackermann (angle of the steering linkages). When the arm is moved
to rearward position (shim in front of the arm), the angle of the
steering linkages changes and gives less Ackermann. By decreasing the
Ackermann, the car gets more turn-in & increased steering at corner
exit, but less cornering speed. The Ackermann can be changed by the
Quick-Saver™ (see page 33).
