We recommend that you DO NOT change the rear track-width, otherwise it
would decrease the stability of the car. But if necessary, you can change the
trackwidth to accommodate different wheels with different offsets.
Initial setting:
Rear Track-width: 189mm
DOWNSTOPS
Downstops limit how far the suspension arms travel downward, which
determines how far upwards the chassis rises. The amount of downward
suspension travel affects the car's handling, as it directly impacts the weight
transfer of the chassis. Restricting upward chassis travel (more downstop)
reduces the weight transfer of the chassis, making the car more stable.
Allowing more upward chassis travel (less downstop) increases the weight
transfer of the chassis, making the car more responsible but less stable; it is
also better on a bumpy track. The effect may change with the type of track
and/or amount of grip available. It is very important to adjust the downstops
such that the left and right sides are equal. Downstops are checked with the
chassis elevated above a reference surface.
Hint: Use Hudy Set-up Board and Droop Gauge Tool.
Perform these initial steps:
1. Remove the wheels from the car. Disconnect anti-roll bars if mounted.
2. Place the #10 7702 support blocks on the reference surface, then place
the chassis on the elevating blocks.
BODIES & AERODYNAMICS
Aerodynamics play an important role in the performance of the car. One
body may simply work better than another body. Aerodynamic effects are
more apparent at high speeds, and have little influence in slow corners.
In general, blunt-nosed bodies are more stable, and have less steering than
bodies with a sloped nose. Another important consideration is the rear wing.
The higher it's mounted, and the bigger it is, the more rear downforce it will
generate. A body with high downforce will help the car get lots of traction
throughout the turns. But high downforce usually comes at the expense of
drag, so the car may not be the fastest on a long straightaway.
Experiment with bodies that have different frontal areas and different wing
shapes to find the one that works best for you. Like most other tuning
parameters, body style is also a compromise. Experiment to find out what
bodies work best at your track.
TRACK-WIDTH
Front track-width affects the car's
understeer and steering response.
Increasing track-width will result in more
understeer, while decreasing it will result
in less understeer and faster steering
response.
The track-width is measured on the
outside of the wheels.
It is important that the track-width is
adjusted symmetrically, meaning that
the right and left wheels must be the
same distance from the center-line of the
chassis.
Hint: Use the Hudy Set-up Board with
Set-up Board Decal nicely marked with 1
mm grid.

Turn both pivot balls IN equally to reduce track-width, turn them both OUT
equally to increase track-width.
Remember to reset the front toe setting by adjusting the lengths of the
steering rods equally to compensate for the width adjustment.
Initial setting:
Front track-width: 189mm
