When tuning the Touring Car make sure that you have equal lengths from one side to the other on the shocks
and upper rods. Also, make sure to have the shock pre-load adjusters at the same setting from left to right.
They do not have to be the same front to rear.
PINIONS
The Touring Car comes stock with the 12 tooth pinion. To obtain higher top speeds you can install a larger
pinion gear onto the motor. This will, however, decrease your acceleration and run time.
TIP:
Smaller pinion
equals more torque, less top speed. Larger pinion equals more top speed, less torque.
CAMBER
Camber refers to the angle at which the tire and wheel ride
in relation to the ground when viewed from the front or
rear. Negative camber is when the wheels lean inward and
positive camber is when the wheels lean outward. Usually
adding a small amount of negative camber (0° to -2°) will
increase traction. However, adding too much camber will
decrease traction. The objective is to keep as much of the
tire as possible in contact with the running surface. Never
put in positive camber. Make sure that both sides are equal.
SHOCK OIL
The Touring Car comes stock with 30 weight oil in the shocks. The handling can be tuned by changing the
shock oil to either heavier (bigger number) or lighter (smaller number). By putting heavier oil in the shocks,
the car will have less chassis roll and become more responsive. Putting lighter oil in the shocks will cause the
car to be less responsive and have more chassis roll. For smooth, high traction surfaces, a thicker oil would
be best. For low traction or bumpy surfaces, a lighter oil would be best.
FRONT SHOCK ADJUSTMENT
Moving the tops of the shocks out (A) will increase steering
reaction but decrease front traction. Moving the tops of the
shocks in (B) will result in slower steering reaction but will
be smoother over bumps and have more front traction.
REAR SHOCK ADJUSTMENT
Moving the tops of the shocks out (A) will increase steering
reaction and decrease rear traction. Moving the tops of the
shocks in (B) will result in slower steering reaction but will
be smoother over bumps and have more rear traction.
