Woodward Power Steering for
‘89 and Earlier 911’s and 914’s
Designed and built for us by Tony
Woodward, this unit is designed to fit into
any ‘89 and earlier 911 using the factory
aluminum cross member or ERP’s 935 style
cross member (ERP mounting kit available
separately). These units are unmatched in
their design and build quality. One of its
most ingenuous features is, the amount of
power assist is adjustable by simply
removing and installing one of 15 differently
sized torsion bars — the result is assist
amounts can range from hardly noticeable
to full finger tip assist! Why power steering?
Today’s ‘89 and earlier 911’s are going
faster and faster due to increased grip from
advances in shock and tire technologies
along with high amounts of aero downforce
— putting a higher and higher demand on
the driver’s strength. Coupled with the high
caster angles, wider rims with considerable
offsets, steering efforts have gone through
the roof. Driver fatigue is often associated
with a heavy steering car. Even more stock
cars benefit from it because it is less
strenuous for the driver, even in short sprint
races. Remember, starting with the ‘89
C4’s, Porsche has run power steering on
every car it has since built; even the entire
range of 996 GT3R’s and Cup cars. Uses
factory 930 style tie rods, tie rod ends and
boots or ERP tie rod bump steer kits — all
available separately.
Factoids: Fits 911’s, 930’s and 914’s with
some minor body modifications. Designed
to be powered by an electric power steering
pump mounted in the front trunk area along
with a small fluid reservoir. Specific
universal joints are available to adapt it to
the factory steering shaft; requires welding.

ERP 935 Front Suspension
The ERP kit benefit is adjustability.
Camber, caster, track width, even wheel
base and width are adjustable. The kit
uses an ERP monoball and its own
cross member to mount the arms and
steering rack; additionally, the arms are
longer and the inner pivot point is raised
20mm to improve the camber gain
characteristics and also reduces the
anti-dive tendencies under hard braking.

Tubular vs. Solid Torsion Bars
The controversy rages on, but the reality
is that the real benefit is lightness, not
that they are “faster acting”. If you have
a very light car - say less than 1900#
and you are trying to get every once out
of the car and you can not use coil
overs, buy the tubular bars.
