Camber:
Camber is the angle of the tops of the tires
when viewed from the front. Negative camber is when
the tops of the tires are angled towards the center of
the touring car. Positive camber is where the tops of
the tires are angled away from the center of the touring
car. Positive camber is very rarely used, if ever. A
small amount of rear negative camber is helpful to
increase traction in the rear. Negative camber at the
front will increase stability. Camber adjustments can
be made on the Street Force GP by turning the
“camber rods,” which are the upper links on the
suspension. Lengthening the camber rod will add
positive camber and shortening the camber rod will
add negative camber.
Shocks:
Changes in shock oils, springs, and pre-load
on the springs can dramatically change the way the
car handles. A thicker shock oil will make the touring
car turn faster but reduces overall traction and
handling over bumpy surfaces. Thinner oil will
increase traction at the expense of steering response
and the car will tend to roll more. In general, shock oils
between 60 and 90 weight will be best for your touring
car. You should experiment some to see what oils
work best for your track and driving style. Shock
springs affect the rate that the suspension rebounds
from a bump. Pre-load on the springs means that the
springs are already compressed some so that the
suspension will rebound faster. Sometimes you will
want to pre-load one side when the track has turns all
or mostly in one direction, for instance an oval track. It
will also increase the ride height.
Before Each Run
• Check for loosened screws on the touring car.
Engine vibration will loosen some of the screws,
particularly in the engine mount area. Use thread
lock on screws that thread into metal parts or use a
metal nut.
• Inspect the air cleaner for a torn or damaged
element. Also look for dirt in the air cleaner element
and wash it if necessary.
• Check the suspension and drive train for binding.
• Inspect all of the wires for damage. Also check the
connectors to make sure all of them are tight and in
the proper place.
• Check the fuel tank and fuel lines for leaks.
• Before starting the engine, turn on the radio and make
sure the servos move easily and in the right direction.
• Before running always check the condition of your
radio system batteries and replace/recharge if
necessary.
After Each Run
• Drain the fuel tank of any leftover fuel.
DO NOT
return it to your fuel jug.
• Put some after-run oil in the carb and turn the
flywheel several times to work the oil into the
engine. This will protect the engine from rusting,
especially when stored for a long period of time.
• Check again for loosened screws.
•
CLEAN
the touring car. Wipe off any oils that have
collected on the chassis, engine end exhaust. Oils
will attract dirt on the next run.
