Our race car suspension
consists of 2 upper and 2
lower arms, a pull rod, a
rocker and a coil (spring +
shock). This year we
introduced a variable rate
suspension which gives us
the softness that we want to
maintain traction on the
road surface and offer the
driver a better ride. It
also gives us the stiffness
necessary to limit body roll
when cornering or nose dive
when driving. When cornering
a weight shift happens, from
the inner tires to the
outside tires. So you have
more weight on your outer
tires which can cause a lift
in you inner tires. And when
that happens you are loosing
traction and when you are
loosing traction you are not
accelerating. So our
suspension is designed to
also limit body roll too.
The wheel rate (which is the
measurement of the
suspension) tells how
stiff/soft the suspension is
on the car. In front at a
stationary position of the
wheel it is 62 lb/in and in
the back it is 74 lb/in. The
spring compresses 2 up and
.5 down.
