Motor Gearing:
The following chart shows final drive ratio numbers for the
TC6. Refer to motor manufacturer’s suggested gear ratio
for starting point. You may need to adjust the gearing
according to your track size.
The following formula’s can be helpful in determining
final drive ratios and pinion size.
TC6 Internal Ratio = 2.0
Final Drive Ratio = # of Teeth Spur x Internal Ratio
# of Teeth on Pinion
# of Teeth on Pinion = # of Teeth on Spur x Internal Ratio

Anti-Dive (front):
Anti-dive is a front arm angle where the rear mount is higher than the front mount. Adding anti-dive reduces weight transfer to the
front on deceleration entering corners. It also reduces caster at the wheel.
Pro-Squat (rear):
Pro-squat is a rear arm angle where the rear mount is higher than the front mount. Running Pro-Squat will increase rearward
weight transfer on power.
Anti-Squat (rear):
Anti-Squat describes a rear arm angle where the front mount is higher than the rear mount. Increasing anti-squat will make the rear
suspension stiffer. It tends to give the car more entry steering and reduce rearward weight transfer on power.
Kick-Up (front):
Kick-up describes the angle of the front suspension arm, where the front mount is higher than the rear mount. Increasing kick-up will
give more entry steering, as well as increasing caster at the wheel.
