COMPONENT
‘LIFING’
CHART
–
As
the
performance
of
our
cars
increases
and
the
number
of
hours
racing
the
cars
complete
grows,
we
are
able
to
more
accurately
predict
the
lifespan
of
a
car’s
components.
Please
see
below,
the
revised
‘Radical
Component
Lifespan
Chart’.
The
chart
gives
the
recommended
life
expectancy
of
components
under
‘normal,
on
‐
track
racing
conditions’.
If
some
of
your
racing
time
is
done
‘off
‐
track’
or
you
hit
kerbs,
pot
holes
or
other
cars
–
hard,
then
you
will
need
to
considering
reducing
the
timescales
recommended.
On
the
other
hand,
more
‘gentle’
trackday
use
will
obviously
extend
the
recommended
time!
One
new
addition
to
the
list
is
the
wing
support
stays,
the
life
of
these
is
greatly
shortened
if
the
wing
is
used
to
push,
and
particularly
pull
the
car
around
in
the
pit
lane,
garages
and
trucks.
It
works
perfectly
to
support
the
wing
and
the
downforce
generated
in
the
direction
intended,
and
not
at
an
angle
to
the
centre
‐
line
of
the
vehicle.

If
you
own
and
drive
the
car,
but
do
not
prepare
or
run
it
yourself,
it
is
your
responsibility
to
be
sure
that
the
engineer
who
does
has
a
copy
of
this
manual,
and
has
read
it.
