For adjusting the rear toe-in you have to purchase the #383302 adjustable turnbuckle set.
Adjust rear toe-in by changing the length of the rear turnbuckles. Shortening the turnbuckle gives MORE rear toe-in; lengthening the turnbuckles give LESS
rear toe-in.
Make sure both rods are adjusted to the same length, and NEVER use toe-out on the rear wheels (always use toe-in).
Rear toe-in angle Characteristics
More rear toe-in · increases stability under braking
· increases stability on power at corner exit
· decreases top speed
· if too much rear toe-in is used, the truck will be
twitchy to drive and harder to recover if it loses
traction
Less rear toe-in · increases steering
· decreases stability on power at corner exit
· increases top speed
· if the truck slides, it will be much easier to
control

You can use shock oils of different weights in a shock absorber.
Shock Oil Characteristics
Thinner · same characteristics as larger pistons holes
Thicker · same characteristics as smaller pistons holes
Silicone Shock Oil
Note that typically you should use piston hole sizes to suit the track conditions rather than
alter the oil viscosity.
Use only the genuine premium
quality silicone shock oils.
The shock oils are availabe
in 50ml size in these
viscosities:
SHOCK OIL
For each type of shock piston (conical or straight holes), there are three pistons with holes of
different sizes.
Piston hole size Characteristics
2 holes · harder damping
· slower chassis weight transfer
· slower response
· decreases chance of bottoming out when landing if used with “thicker” oil
· decreases chassis roll if used with “thicker” oil
· use with thinner oil if track is rough
4 holes · softer damping
· increases traction
· quicker chassis weight transfer
· quicker response
· increases chance of bottoming out when landing if used with “thinner” oil
· increases chassis roll if used with “thinner” oils
· use with thicker oil if track is smooth
PISTON HOLE SIZE
You can use shock springs of different rates to alter performance.
Shock spring Characteristics
Softer · more chassis roll
· more traction
· better on bumpy tracks
· increases chance of bottoming out when landing
Stiffer · less chassis roll
· less traction
· more responsive
· better on smooth tracks
· decreases chance of bottoming out when landing
SHOCK SPRINGS
You can use shock springs of different rates to alter performance.
