A final note about camber links: keep an eye on the balance of the front and rear links.
Having a short link up front and a long one in the back can make the car feel less
confident and consistent. If you find yourself liking a long rear link, try a longer front one
to go with it, and vice versa.
SHOCKS
The shock absorbers on your X – 6 Cubed offer much adjustment potential, and with
good reason: they’re working all the time, through corners, bumps and jumps, even just
going straight! On your shocks you can change the spring rate, the damping and pack,
mounting locations, and travel limits.
Changing the spring rate is pretty easy: change the springs. AE makes standard
shocks, the V2 shocks, and big bores with lots of different springs, which will give you
plenty of options. In general, stiffer springs will make the car feel more direct and jump
a little better; they’re suitable for high traction surfaces. Softer springs are better for
bumpier surfaces, and can help generate traction on low-traction tracks. That holds true
for each end of the car. Stiffer front springs will take away steering but can make it
easier to drive, while soft springs add steering. Too soft will make the car hook spin out
mid-corner. Stiff rear springs will add steering, especially in long sweepers, but at a
loss of rear traction. Going softer in the rear will add bite, good on bumpy tracks, but
take away steering. The big bore shocks & springs generally give a more “plush” feel,
especially on rough tracks or those with large jumps. By using spring retainers from
other manufacturers, big bore springs can be put on standard shocks; this often works
very well on smoother indoor tracks with smaller jumps.
The damping in your shocks is a combination of the pistons inside and the oil they travel
through. Heavier damping (thicker shock oil) will make the car smoother on the track,
and better landing jumps, but will make the car bouncy in bumpy or choppy sections.
Lighter damping makes the car more reactive overall and better through bumps, but it
will bottom out more jumping and be slightly harder to drive.
You should also consider the “pack” your shocks have. Due to fluid dynamics, the
resistive force of our dampers greatly increases as the piston moves faster. The faster
the piston moves, the more it “packs up,” and it does this on any stroke, even if there is
only one. The smaller the shock piston holes, the more quickly the shock will pack and
the greater the force will be. Larger piston holes are the opposite. By adjusting the
shock pistons and oil together, you can tune both the static damping and pack
separately. To change the pack while leaving the static damping similar, adjust the oil 5
wt for each piston change. So if you started with #2 pistons and 30 wt oil, you could:
