The compact MPV of Proton Exora with 2 variants was released in 2009. Followed by the Facelift revision of Proton Exora Bold debuted in 2011.
Both variants of Proton Exora were powered by the 1.6L CamPro CPS engine and limited to a four-speed automatic transmission. While the Proton Exora Facelift is powered by the new 1.6L CamPro CFE DOHC I4 turbocharged engine and CVT technology.
Both generations were using the same car chassis platform. Let’s move forward to the suspension, the suspension is made up of Independent MacPherson struts at the front and torsion beam system at the rear.
How many bars available for Proton Exora and Proton Exora Bold?
In Ultra Racing, the bars that are available for Proton Exora and Proton Exora Bold are Front Strut Bar, Rear Anti Roll Bar, Front Anti Roll Bar, Front Lower Bar, Rear Lower Bar and Side Lower Bar.
The functionality of each of the bars after installed on your Proton Exora & Exora Bold are explained below.
Stage 1: Front Strut Bar & Rear Anti Roll Bar
Stage 1 which includes Front Strut Bar and Rear Anti Roll Bar, is the primary set to enhance the performance of your car.
Front Strut Bar / Front Tower Bar
The Proton Exora & Exora Bold doesn’t come with the OEM front strut bar from the car manufacturer. Ultra Racing has developed a 2 points front strut bar, located at the top of the absorber (left and right) in order not to affect the normal procedure of service and maintenance.
The car chassis will affect the left and right strut tower and suppress changes in body distortion that occur during running. Furthermore, continuous stress will cause distortion little by little. As known by majority, tire friction, suspension forces, defects from rain water and old car with age will affect a car’s life span. Aftermarket suspension and modifications will also increase the burden of the car chassis.
One of the methods to deal with such a situation is to install a front strut bar/front tower bar, by connecting the left and right strut towers to increase rigidity. Apart from being easy to install, it is the most effective reinforcement part that demonstrates high performance.
Rear Anti Roll Bar / Rear Sway Bar
The OEM rear suspension setups of the Toyota GR Yaris comes with multi-link suspension and OEM rear stabilizer bar. The OEM rear anti roll comes with a solid 21.5mm. Thus, Ultra Racing decided to develop a solid 24mm, the purpose of upgrading the OEM rear anti roll bar as it significantly improves the handling performance and maintain the comfortability of the car.
A normal road is not flat as a race track, it comes with an uneven and bumpy road surface. When the left and right suspension alignment are different such as during cornering, the stabilizer twists the bar and suppresses the roll by its restoring force. This will result in an understeer or oversteer and also there’s a risk to lose control if over body roll.
By installing the suitable size of anti roll bar, it is possible to suppress the roll of the vehicle’s body without stiffening the suspension and improving cornering and traction. In addition, since the left and right wobbling is suppressed and the posture is stable, there is no discomfort and the risk of motion sickness is reduced.
Stage 2 (Lower Arm Bar)
Stage 2, comprising Front Lower Bar, Mid Lower Bar, Rear Lower Bar, Rear Lower Side Bar, Rear Strut Bar and Room Bar for Toyota GR Yaris are able to reduce the car chassis flex and strengthen the main chassis platform. It is highly recommended for heavy load vehicles such as SUV or MPV as it helps to enhance the stiffness and handling during higher speed and cornering.
So, it’s time for you to push the handling and performance to the limits with Ultra Racing now!
