These are some guidelines for choosing different spring rates
for your setup on your Kyosho Inferno. Remember that every change you make to
your setup will effect something else. It is a good idea to experiment by
changing settings to get a feel for how changes effect your car with your
driving style. Further reading on the subject of chassis set will also help. Try
and hang with experienced drivers at the tracks you race at will also help
immensely!

Explanation for the
spring rates in the charts above:
The part number of the Kyosho spring has the wire thickness
and number of turns included in it.
For example:
IF350-716 equates to:
7 turns of 1.6 thick wire.
This can be extrapolated to all the springs and you will see
the pattern evolve for the spring rates.
Thicker wire = stiffer spring
More turns in wire = softer spring
Just think of this like a spring is a piece of wire. If you
straightened out the wire and held it on one end, the longer it is, the easier
it would bend by pushing on it from the opposite end. The same would hold true
for a thinner piece of wire, it would be easier to bend as well. This is how
springs are actually working. The longer the wire the easier it is to bend and
therefore the softer spring rate it has. An advantage of lower turns and thinner
wire is you can create a spring with lighter weight vs. a spring with thicker
wire and more turns. Keep this in mind when choosing springs to run as well.
I hope this explanation helps rid some confusion about how
the above charts work.
