Power
Slot®
Rotors
Power
Slot®
rotors
are
1-piece,
slotted,
direct
replacement
discs
for
your
factory
brake
system
and
stock
calipers.
They
offer
improved
cooling
as
well
as
other
advantages
the
competition
doesn't
offer.
Launched
in
1998,
Power
Slot®
was
the
first
premium
slotted
replacement
rotor
program
in
North
America.
Innovations
include
e-coating,
double-disc
grinding,
full
machining,
mill
balancing
and
center-split
castings,
as
well
as
the
availability
of
directional
vanes,
cryogenic
treatment
and
the
use
of
Power
Alloy.
Today,
Power
Slot®
covers
more
than
2500
applications,
all
machined
in
Power
Slot's®
California
manufacturing
center.
Every
Power
Slot®
rotor
is
a
direct
replacement
for
a
factory
brake
rotor,
allowing
the
retention
of
factory
calipers
in
the
system.
Power
Slots
Power
Slot®
rotors
feature
a
signature
"short
slot"
design.
The
slot
improves
brake
system
performance
by
wiping
away
the
debris
of
used
friction
material
that
otherwise
accumulates
between
the
rotor
and
pad.
This
keeps
fresh
pad
material
exposed
to
the
rotor
surface
and
helps
prevent
pad
glazing.
The
edges
sweeping
the
pad
slightly
increase
the
effective
coefficient
of
friction,
or
“bite,”
amplifying
brake
system
response
to
pedal
input.
By
providing
an
escape
path
for
water,
slotted
rotors
can
also
improve
initial
brake
response
under
wet
conditions.
E-Coated
Finish
Every
Power
Slot®
rotor
is
finished
with
a
black
e-coating
on
both
sides
of
the
hat,
inside
the
cooling
vanes
and
on
the
outside
edge.
E-coating
is
a
superior
electro-statically
applied
finish
designed
to
withstand
400
hours
of
salt
water
exposure
without
rusting.
This
is
especially
important
on
both
mounting
faces
of
the
hat
where
it
touches
the
hub
flange
and
back
face
of
the
wheel.
Any
accumulation
of
rust
in
these
areas
can
lead
to
installed
lateral
runout
issues.
Double
Disc
Ground
Power
Slot®
rotors
feature
a
double
disc
ground,
taper
free
finish.
Double
disc
grinding
ensures
parallelism,
eliminates
run
out
and
provides
near
perfect
disc
thickness
variation
(DTV).
Double
disc
grinding
leaves
a
non-directional
finish
on
the
friction
surface
area
for
more
effective
pad
and
rotor
break-in.
This
special
finish
also
provides
quieter
and
smoother
stops.
Machined
Finishes
Power
Slot®
rotors
feature
100
percent
fully
machined
finishes
including
rotor
hats.
This
extra
process
provides
better
rotor
balance
and
creates
a
cleaner,
more
finished
looking
component.
Mill
Balancing
Power
Slot®
brake
rotors
are
mill
balanced
to
a
tolerance
of
less
than
2
oz-inch.
This
additional
machining
operation
reduces
feedback
associated
with
rotor
vibration
and
provides
a
smooth,
confident
application
of
braking
force.
Split
Castings
Center-split
core
castings
provide
proper
heat
transfer
and
thermal
efficiency,
resulting
in
superior
braking
power
and
safety.
Directional
Vane
Design
Most
Power
Slot®
rotors
match
the
original
factory
cooling
vane
design.
In
the
most
popular
sports
car
and
light
truck
applications,
Power
Slot®
has
improved
the
design
by
using
directional
(left-
and
right-handed)
vanes
to
improve
cooling.
This
represents
a
distinct
upgrade
from
the
original
equipment
rotors, which
usually
feature
a
straight
vane
or
pillar
vane
design. The
directional
vane
is
a
more
efficient
air
pump.
The
resulting
increase
in
airflow
translates
into
greater
resistance
to
brake
fade
and
faster
recovery
from
temperature
spikes
generated
by
aggressive
braking
maneuvers.
