Triple Eight relatively easily. It’s obviously
part of the work James and Ty did was
integrate that into the car and how it would
look.” Around this time an interim alumin-
ium version of the console was designed and
produced to fit the new keypad module.
At this point think about the height of
the four 2014 WR drivers. Yep you’ve got
Tander and Percat in the beanpole category
and Courtney and Slade who, err, aren’t.
The beanpoles felt the solid-mounted
shift lights being argued for by their shorter
teammates could be of benefit, but needed
to be mounted higher than on the steering
As a result, a prototype shift light module
was mounted on top of the composite dash
pad in Percat’s car (#222).
Initial on-track evaluation was made by
Percat at the pre-Sandown Winton test day
in early September. Other drivers also evalu-
ated the system and provided feedback.
The modified aluminium console allowed
assessment of the keypad module and the
electrical change, which simplified the wiring
system to a single connector.
Other feedback at the test was positive.
Drivers liked the steering wheel size, an off-
the-shelf Sparco product, and switch layout.
The console was easy to reach and use. The
only change suggested was the location of
the pit speed switch. The prototype com-
ponents remained fitted for the Sandown
event to #222. Afterwards, the drivers
reported the re-location of the pit speed
switch was an improvement.
The prototype components remained fitted
for Bathurst and Surfers Paradise. After
more evaluation, including durability testing
of the switches and so on, the design was
approved and two versions of the steering
wheel were released in late October:
• Version 1 WR-70031897 Steering
wheel with dash. This included the external
shift-light module, mounted on top of the
composite dash pad. This was as per the pro-
totype used in #222.
• Version 2 WR-70032105 Steering wheel
without dash and shift lights. The dash and
shift lights were mounted to the steering
Successful evaluation of the keypad
module meant approval was given to
proceed with a composite console. Design
work was done through October, with
release of component WR-70032843 and
aluminium tooling late that month.
“Going to a composite obviously required
some tooling, so that required consult-
ing with the composite department and
machine shop as to what they can make and
once you settle on the design it is a case of
tooling up and making the first piece and
then dummy fitting to make sure it meets
the requirements,” says Nilsson. “We were
comfortable with where we got to on that
one so we didn’t rapid prototype it. We
tooled up, made our first pieces and went
through that process.”
The original prototype continued in #222
at Phillip Island, while #22 (Courtney)
upgraded to version two, meaning the steer-
ing wheel binnacle was used for the first
time. Courtney also tested an interim alu-
minium version of the jelly pad.
Courtney felt the solid-mounted dash and
shift lights were an improvement because
they did not move around and were more
stable in peripheral vision.
But he requested the radio paddles
mounted behind the steering wheel spokes
Production of the first composite console
was completed that month.
At Homebush, #22 ran the same equip-
ment as Phillip Island but with a modifi-
cation to the paddle length. Meanwhile,
#222 ran the first full production assembly
of version one steering wheel and was
upgraded with the composite console.
“We got to the end of last year, signed it
off as an installation and then production-
ised it,” says Nilsson. “We still had a few
tidy-ups to do through the design, just
through bits and pieces of feedback, but
then James (Stone) spent towards the end
of last year finalising the design and releas-
Final specifications of two steering wheel
• WR-70033067 Steering wheel without
dash and shift lights. Dash and shift lights
to be mounted to the steering column bin-
• WR-70033068 Steering wheel with
dash. External shift-light module, mounted
on top of the composite dash pad.
ABOVE & LEFT: With the dash and shift
lights away from the steering wheel,
Walkinshaw Racing designed a new
switch panel (or console), where the
majority of functions can now be found on
a programmable keypad module.
The version of the steering wheel where the dash and shift lights
are instead hard-mounted behind the wheel on the steering column.
