The same logic applies to fitting front and rear
adjustable SuperPro Roll Control Sway bars, this is
to say, always have the rear bar set at a higher rate
position than the front. We do all of the hard work
for you in determining Swaybar diameter for
optimal increases in rate over the OE sway bars to
increase roll stiffness for a particular application.
Swaybars will make the suspension system and
tyres perform better, making the car more
responsive while delivering more grip. Fitting
SuperPro Roll Control Swaybars offer all round
improvements in handling and grip; it is the best

Q. If we're constantly being told polyurethane bushes are a
superior replacement alternative to rubber bushes, then
why do all car manufacturers continue to use rubber over
poly bushes? Why is it that aftermarket bushes are almost
always polyurethane and not, say, a hardened rubber
SuperPro: It all comes down to cost. It is cheaper
and more cost effective to mass produce a rubber
suspension component than it is to produce a
polyurethane component. Also, the vehicle
manufacturer is predisposed to appealing to a mass
market in making their cars feel comfortable to
A better, more durable and resilient material than
rubber is polyurethane. This is why PU
(polyurethane) is the “go to” replacement material
for performance and handling. However, it is all in
the mix. PU material is used to make everything
from skateboard wheels to carpet underlay!
SuperPro is a class of synthetic isocyanate resin
base material converted with various curing agents
to become a more durable product with the best
features of both rubber and PU.
The secret formulation and molecular structure of
our SuperPro material ensures that it is energy
absorbent; a bushing incorporated into a
suspension system has to accommodate
geometrical interference and reduce the impact of
energy transmission. It also has to be lightweight
and strong, resulting in a product that is superior
to OEM rubber products and all other opposition
products. We think of our blend of polyurethane as
an elastomer, or synthetic rubber.
The best way to think of SuperPro versus Rubber is
the same as engine oil, mineral oil versus synthetic
oil. SuperPro is a synthetic rubber with all of the
undesirable characteristics of rubber eliminated
and all the desirable ones enhanced. Having said
all this, it must be remembered that not all brands
of PU suspension bushes are the same!
Q. How does SuperPro perform test fitments on the cars it
makes products for? Is there real-world testing to the cars
before and after?
SuperPro: Our process starts at our R & D
department. In our R & D workshop we look at OE
design of the suspension set-up, the positioning of
the bushes and their function. We then apply our
knowledge of the properties of the material we
developed to produce a bushing or arm package
that will work the way we want it to.
Our primary goal is to enhance the function of the
bushing with zero increase in NVH (Noise, vibration
and harshness). As SuperPro is an Australian
company, what we manufacture predominately
services the Australian aftermarket repair sector. If
you have your road car repaired in Australia it will
have SuperPro or some other PU fitted as the first
option. This makes us acutely aware that our
bushings have to be better than OE, in all respects.
We enjoy the reputation as the best PU
manufacturer servicing this sector of the market.
Performance and handling benefits of SuperPro are
an extension of what we do.
Once our engineers have looked over the car, we
measure up and start the development process of
both SuperPro bushings, Arms and Roll Control
Sway bars. We make all our own patterns, moulds
and pour our bushings in our Brisbane facility. We
control the process from start to finish. Our
Swaybars are designed, rate tested and
manufactured in the same facility. It is important
to point out that we use the highest grade of
Australian spring steel in the manufacture of our
Swaybars, this allows us to achieve better rate
results from smaller diameters. Every Swaybar has
three layers of powder coating to insure they have
the highest level of corrosion resistance and are
supplied with SuperPro bushings.
Every Suspension Arm, Bushing and Swaybar is
test fitted to our R & D vehicles to ensure correct
fitment, alignment and function. All vehicles are
compared back to back against the standard car
and travel a required distance and time before they
are re-checked and assessed. On most
development projects we can get track time, as we
did with Harding Performance and their pretty fast
VW Golfs at all the Hot Tuner Challenges in the
development of our VAG range. We are always
assessing feedback, and if necessary, tweaking the
design of bushings.
For us R & D is an ongoing commitment making
SuperPro engineered to outperform.
