CASTER ADJUSTMENT
FRONT CASTER
For most conditions, 5.0 deg front caster is a
good starting point. Decreasing caster increases
entry steering but will cause more on-power push.
REAR CASTER
A good starting point for rear caster is 0.5°.
0.5 caster generates more cornerspeed and
makes the car easier to drive in long sweepers.
Recommended for both carpet and asphalt tracks.
5.5 caster improves rotation and steering, mainly
recommended for tight tracks.

ALU UPPER CLAMPS - 1.0mm
The new upper clamps move the inner pivot 1.0mm closer to
center. This position lengthens the upper arm and reduces
camber gain to free up the car. Mid corner steering improves
in long sweepers, and traction rolling is reduced in very high
traction carpet conditions. Recommended for large open tracks
or high traction carpet tracks.
