. A longer front camber link will usually make the car feel stiffer. This will help keep the car flatter with less roll, but can
make the car handle worse in bumpy conditions. A shorter front camber link will result in more front end roll. This will increase
high-speed steering and make the car better in bumps. Too short of a front link may make the car feel twitchy or "wandery"
meaning that it may be difficult to drive straight at high speed.
Front Shock Location
can be adjusted easily by simply moving top of the shock to another hole in the shock tower. The standard
location (center hole in the tower) works best on most tracks. Moving the top of the shock out one hole will result in an increase
in steering and the car will react quicker. Moving the top of the shock to the inside hole in the tower will slow the steering response
time and make the car smoother in bumps.
The bottom of the shock can also be moved in or out on the suspension arm. Moving the bottom of the shocks to the inside hole
in the arm will result in more low-speed steering and less high-speed steering. Mounting the shocks in the inside hole will require
limiters in the shocks to limit the travel, and the springs should be changed to stiffer ones. Moving the bottom of the shocks to the
outside hole will reduce overall travel, increase high-speed steering, and reduce low-speed steering. This position may be good for
oval tracks and high-traction surfaces.
Rear Shock Location
can be changed just as easily as the front. Again, the standard location is the best place to start for most
tracks. Moving the top of the shock in on the shock tower results in less side-bite (traction in corners) but makes the car smoother
in bumps. Moving the top of the shocks to one of the two outside holes will give the car more forward traction and side bite as well
as keeping the car from bottoming out on big jumps. A softer spring should be used if the shocks are mounted in one of the two
outer holes in the tower.
Moving the bottom of the rear shocks to the outside hole in the arm will improve stability but may not handle bumps as well.
You may also notice that the car is faster in the turns. The downside is that the car will not straighten out or "square up" as well.
Rear Anti-Squat
is one of the most commonly used adjustments of the XXX-BK2. As per assembly instructions, there is 1
degree of antisquat. Adding the additional shims under the front of the block will result in 2 degrees. This will result in less side-bite,
which will cause the car to have more steering from the rear end. It will also give the car more forward traction and get more air
off of large jumps. By removing the shims will result in 0 degrees of antisquat. This will have more side bite but will have less
forward traction and get less air off of jumps.
Rear Hub Spacing
can be adjusted by moving the spacers at the front and rear of the hub carrier. You will probably find that the
middle (standard) location works best on just about every track. Spacing the hub back might help on large, high-speed, outdoor
tracks. Spacing the hub forward might help on tight, indoor tracks.
Battery Location
is sometimes overlooked, but can be a useful adjustment. Start by running the battery spaced forward. Moving
the battery back can improve rear traction on slippery tracks. Moving the battery back too far can cause the rear end to swing
though turns on some tracks. This is a result of having the weight too far back.
Arm Length Adjustment (VLA),
the
XXX-BK2
is like having four cars in one. With the addition of a longer arm position, you can
have an aggressive setup by using the standard mounting positions or a more conservative setup by using the longer position. For
most tracks the standard setup will work well, but for extremely bumpy, rutted, and high bite tracks the longer arm length will help
slow the reactions of the car, making it feel less twitchy.
The longer arm setting will help to increase steering during the middle, exit, and during on power turns. It can also be used as
a valuable tuning aid to balance your car if you are experiencing too much chassis roll in the front or rear. For example if the rear
of the car is experiencing too much chassis roll in the front, then the longer arm position could be used to balance the car. For
instance, European tracks often have long sweeping turns, which require a very stable car, the longer arm position should prove
to work very well.
We are sure that you will find the
XXX-BK2
to be the most versatile and easiest car to drive fast with great consistency. We
at Team Losi hope this information helps you to enjoy your
