Duratrax Raze, Assembly And Operation Manual

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
buggy. 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
comes with 2° and 3° rear toe-in blocks.
RIDE HEIGHT
The Raze shocks use preload clips to adjust the buggy’s ride
height. By adding the included preload clips to the shock, the
buggy’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 buggy 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 are that if the rear end is stiff it will give
the buggy 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. Optional springs are available to tune your Raze.
See our website (www.duratrax.com) for a complete listing
of optional parts.
Thinner shock oil makes the shocks react faster which works
well on rough tracks, but makes the buggy less stable and
may cause the buggy to bottom out over large jumps. Thicker
shock oil makes the buggy smoother over large jumps and in
straights, but less reactive over rough sections.
DIFFERENTIAL OIL/GREASE
The Raze comes with sealed differentials filled with medium
grease. You can tune the buggy 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.
