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
