Steering
Wheel
Fitment
Explained
Aftermarket
steering
wheels
are
"universal"
(not
vehicle
specific),
but
will
require
a
hub
adapter
that
is
compatible
with
your
vehicle
and
has
the
correct
bolt
pattern
for
your
steering
wheel.
There
are
two
bolt
patterns
in
common
use
today:
-
6x70mm
PCD
-
NRG,
OMP,
Sparco,
MOMO,
Grip
Royal,
Works
Bell
-
6x74mm
PCD
-
Nardi,
Personal
Hub
adapters
with
12
bolt
holes
typically
support
both
of
the
above
patterns.
However,
"short"
hubs,
and
quick
release
adapters
(which
are
optional),
often
only
support
one
of
the
two
above
patterns,
so
be
sure
to
double
check
that
all
of
your
components
are
compatible
with
one
another.
