“A lot of time was spent optimising the grip shape of the steering wheel. Having played a significant role in the design and execution of JDub’s GT-style steering wheel, we caught up with #88 race engineer Dave Cauchi to explain the finer details of the entire process.
The team collaborated with partners HP 3D Printing and EVOK3D to produce three main pieces for the race car steering wheel: a two-part mould to form the soft polyurethane exterior that wraps around and cushions the steering wheel lightweight cores that sandwich the armature plate and form the bulk of the steering wheel rim and the housing for the mounting of switchgear and lights to the hub. Here at the Red Bull Holden Racing Team, we like to tackle the wheely big issues.Īfter we asked Jamie ‘JDub’ Whincup to step in front of a camera and explain the difference between the standard Supercars steering wheel and his preferred ‘GT style’ wheel, we thought we’d dig a bit deeper and discover what it takes to design, build and test one of the most important components of our supercars.Ī racing car steering wheel is an assembly that typically includes three parts: an armature and grip (rim), or the part that the driver holds to steer the car (this is typically made from a strong aircraft grade aluminium) the hub and quick-release mechanism, which connects the armature to the steering column and various switchgear and lights that are mounted to the armature or hub and allow the driver to exert control and receive information about the state of the car.
