adjustable
Rear
Upper
Arms
(RUA)
are
an
absolute
necessity
to
maintain
proper
rear
camber
and
reduce
tire
wear
on
the
street
and
track.
The
stock
BMW
setup
has
an
aggressive
camber
curve
through
bump
travel,
which
is
very
apparent
on
lowered
cars.
Excess
negative
camber
causes
premature
tire
wear
on
the
inside
edge,
and
reduced
traction
on
acceleration
while
too
little
camber
will
limit
rear
grip
while
cornering.
Our
Rear
Upper
Arms
provide
a
wide
adjustment
range
for
precise
rear
camber
alignment
that
is
easily
optimized
for
street
or
track
driving
while
eliminating
bushing
deflection
with
smooth
articulating
Teflon
lined
rod
ends
in
place
of
the
soft
factory
rubber
bushings.
Our
kit
replaces
the
factory
links
commonly
referred
to
as
the
rear
wishbone
and
rear
guide
links.

FK
Spherical
Bearings
and
Rod
Ends
are
manufactured
in
Connecticut
and
utilize
a
Teflon
liner
to
provide
quiet
operation,
lower
friction,
smooth
articulation,
and
eliminates
bushing
deflection
under
load.
The
liner
is
also
self-lubricating
and
self-cleaning,
offering
robust
reliability
for
street
and
track
use.
The
PTFE
liner
is
chemically
bonded
to
the
inner
diameter
of
the
race,
and
offers
a
very
high
load
carrying
capacity
that
has
greatly
increased
dynamic
wear
characteristics.
The
operating
temperature
of
the
liner
ranges
from
-65º
to
325ºF,
offering
robust
reliability.
Sold
