TOE-IN AND TOE-OUT
Toe-in is when the fronts of the tires point towards each
other. Toe-in increases stability during acceleration and
high speed. However, toe-in also decreases steering when
entering a corner. Toe-out will increase steering into corners,
but will decrease the overall stability during acceleration. The
front typically is set-up with 0° to –2° of toe-in. Toe-out is
when the fronts of the tires point away from each other.
Rear toe-in affects the traction of both the front and rear of
the truck. Rear toe-in increases the amount of traction in
the rear, but decreases steering. Decreasing rear toe-in will
increase steering, but will give less rear traction. The Raze
ST comes with 2° and 3° rear toe-in blocks.
RIDE HEIGHT
The Raze ST shocks use preload clips to adjust the truck’s ride
height. By adding the included preload clips to the shock, the
truck’s ride height will increase. Removing the preload clips will
lower the ride height. Typically, a good place to start is with the
ride height set so the dogbones are parallel to the surface.
FRONT SHOCK ADJUSTMENT (IN AND OUT)
Moving the tops of the shocks out will increase steering
resulting in quicker reaction. Moving the tops of the shocks
in will result in slower steering reaction, but will be smoother
over bumps. Mounting the bottoms of the shocks in the inside
holes will give more slow speed steering but will take away
some high speed steering.
REAR SHOCK ADJUSTMENT (IN AND OUT)
Moving the tops of the shocks in will result in more traction
in the corners and will be smoother over the bumps. Moving
the tops of the shocks out will give the truck more steering
and handle large jumps better.
SHOCK OILS AND SHOCK SPRINGS
Many different combinations can be used between the shock
oils and shock springs. Some basic guidelines when setting
up the Raze ST are that if the rear end is stiff it will give the
truck more steering and have less rear traction. Stiffening
the front will result in less steering and more rear traction.
Changing the shock pre-load adjusters results in ride-height
change only. It does
not
change the spring tension.
Thinner shock oil makes the shocks react faster which works
well on rough tracks, but makes the truck less stable and
may cause the truck to bottom out over large jumps. Thicker
shock oil makes the truck smoother over large jumps and in
straights, but less reactive over rough sections.
DIFFERENTIAL OIL/GREASE
The Raze ST comes with sealed differentials fi lled with
medium grease. You can tune the truck by changing the oil/
grease either heavier or lighter.
• For loose track conditions, use a lighter oil/grease. For high
traction conditions, use a thicker oil/grease.
• For more pull in the corners, use a thicker oil in the front
than in the rear.
• To reduce steering and increase overall forward traction,
use a thicker oil in the rear than in the front.
