Final Drive Chart: The chart provided below gives you the final drive of the motor to spin the
axle 1 revolution. This chart is NOT just the pinion and spur, but has the transmission ratio
included as well.

Rear Toe Stagger:
Rear Toe Stagger: Difference in the amount of Rear Toe-In among the rear tires. Typically used
only on high bite tracks with MORE toe-in on the Left Rear tire than the Right so the rear of
the car helps turn the car LEFT under acceleration.

Wheelbase (Front End): Wheelbase is the distance between the front and rear axles.
Running the entire front end assembly in the forward position makes the wheelbase longer
and therefore more stable on long/fast tracks with flowing turns. Running the entire front
end assembly in the rear position make the wheelbase shorter and therefore more suitable for
short-tracks where you are constantly turning.
Wheelbase (Rear End):

Wheelbase (Rear End):
Wheelbase (Rear End):
Wheelbase (Rear End): This adjustment uses the plastic spacers on the kingpin the rear
bearing carrier rides on. With the spacers in front of the carrier it will lengthen the wheelbase
but will increase steering. If the spacers are behind the carrier it will shorten the wheelbase
but increase rear traction. This is completely backwards from how it works for the Front End
only because in the rear of the car you have the weight of the motor and the torque it creates.
Shortening the wheelbase here makes more of the car hang over the rear tires and promotes
more weight transfer.
- To determine the final drive in your car:
1) Divide the Spur Gear by the Pinion Gear, which
equals a “Ratio”.
2) Multiply the “Ratio” by the “Transmission Ratio”
which will equal your “Final Drive”.
***Transmission Ratio = 2.4 for this car.***
- Gearing choice can vary greatly depending
on track size, surface type, amount of traction,
you motor and driving style. For starters
consult your local hobby dealer or fellow
racer at your local track for the ideal gear
choice for your application.
