Note:
If
you
intend
carrying
a
passenger
for
the
majority
of
the
time,
the
above
procedure
should
be
carried
out
with
him/her
in
the
car.
BRAKE
BIAS
SETTINGS
Set
central
to
two
turns
towards
front
(clockwise
on
the
dash
adjuster).
Further
adjustment
can
be
made
to
suit
individual
circuits
and
tyre
configurations.
Adjust
bias
to
the
rear
in
wet
conditions.
GENERAL
CAR
PREPARATION
To
keep
your
Radical
looking
at
its
best
the
fibreglass
and
carbon
fibre
items
can
be
quickly
and
effectively
cleaned
with
polish,
while
all
chassis,
suspension
and
panel
parts
can
be
kept
looking
new
and
corrosion
‐
free
by
wiping
them
down
with
a
cloth
sprayed
with
WD40.
DRIVING
TECHNIQUE
If
you
are
unfamiliar
with
a
sequential
shift
car,
it
is
recommended
that
you
change
gear
using
the
clutch
when
going
both
up
and
down
the
gearbox.
Once
you
have
become
familiar
with
the
technique,
changing
gear
going
up
the
box
can
be
achieved
by
lifting
the
throttle
slightly
and
simultaneously
‘snicking’
the
gear
in,
without
depressing
the
clutch.
On
down
‐
changes
it
is
imperative
the
driver
depresses
the
clutch
and
raises
the
engine
speed
before
engaging
the
gear.
Smooth
gear
changes
can
be
best
achieved
by
using
the
‘heel
and
toe’
technique.
Only
change
down
one
gear
at
a
time.
As
with
any
dog
‐
engagement
gearbox,
aggressive
gearchanges
will
damage
the
gear
dogs
which
will
result
in
gear
engagement
problems.
Only
use
a
maximum
of
6,000–7,000rpm
while
getting
used
to
driving
your
SR5.
If
you
accidentally
down
‐
change
instead
of
an
up
‐
change
you
are
less
likely
to
over
‐
rev
the
engine.
If
you
do
over
‐
rev
the
engine,
make
your
way
slowly
back
to
the
pits
and
check
the
yellow
recall
button
on
the
dash.
If
you
have
revved
the
engine
over
9,000rpm,
switch
off
and
return
the
engine
to
Powertec
for
inspection
immediately.
Ensure
that
the
tyres
and
brakes
are
fully
up
to
temperature
before
pushing
hard.
The
Radical
SR5
has
phenomenal
braking
performance
and
will
carry
considerable
speed
into
a
corner.
Practice
braking
hard,
but
come
off
the
brakes
smoothly
and
concentrate
on
carrying
speed
into
a
corner.
On
exiting
the
corner,
the
throttle
should
be
fed
in
progressively.
Driving
smoothly
is
the
secret
to
quick
lap
times.
One
final
tip:
CHECK
YOUR
OIL
LEVEL
BEFORE
EVERY
RUN
!
The
SR5
can
pull
over
2.5g
when
cornering.
If
you
do
not
have
the
correct
oil
level,
even
with
a
dry
sump
motor,
you
risk
starving
the
engine
of
oil,
with
expensive
consequences.
