Gazoo Racing's GRFour Yaris (GXPA16), also known simply as the GR Yaris, is one of the hottest cars to hit the streets in the last 12 months. Toyota Heritage were very lucky to be involved with one of the very first cars to arrive on the East Coast and started making plans for production of sway bars immediately.
GR Yaris sway bars are one of the newest products to join the many that Toyota Heritage already offers the Toyota enthusiast.
Once Toyota Heritage had a GR Yaris available and could get it up on the hoist the DNA of Toyota AWD was imediately apparent. The GR Yaris factory sway bars were measured up and assessment was made as to how easy it would be for GR Yaris enthusiasts to undertake a sway bar swap out at home. Toyota Heritage could see that the GR Yaris rear bar would be a realtively easy affair, and could be done with simply taking off the rear wheels and lowering the exhaust. The rear sway bar also can be fitted using the factory supplied links from Toyota. The front sway bar on the GR Yaris would need the sub-frame lowered though.
The sway bars were then taken into the Toyota Heritage workshop where some baseline testing was undertaken to assess the torsional rigidity of the GR Yaris factory bars (nb not Rallye Pack bars). This process essentially requires the GR Yaris sway bars to be braced in a special test rig and a standardised suspended weight applied to one end. Several tests must be undertaken to get a good data set of the torsional movement of the bar end.
After the first Toyota Hertage GR Yaris sway bars were produced they were also taken into the Toyota Heritage workshop and were also rigged-up and tested in the same fashion as the factory GR Yaris sway bars. Toyota Heritage parametric tested its 22mm rear GR Yaris sway bars along with its 22mm and 24mm front GR Yaris sway bars in this early phase of development.
The results were most interesting. Toyota Heritage's standard GR Yaris front and rear bar package, which is ideal for street and track use, provides increased torsional stiffness of 15% to 30% (22mm rear) and -20% to 15% (24mm front) over factory sized bars.
Perhaps the best thing about Toyota Heritage's GR Yaris sway bars is that the customer can select any size for front or rear starting from 18mm and going up in 1mm increments to 24mm diameter. Then for the serious GR Yaris owner Toyota Heritage can also offer bar thickness beyond 24mm diameter. Already a number of 25mm rear bars have been sold but so too have 18mm rear bars. If red is not your preferred colour then Toyota Heritage can also powder coat its GR Yaris sway bars in a colour of your choice. Its all down to the GR Yaris owners preference and diring style but there is certainly a sway bar size available from Toyota Heritage that suits most any application from Motorkana to Rally to Track.
Toyota Heritage GR Yaris sway bars are Australian made, three-way adjustable and powder coated to the highest standards, and come complete with bushes, brackets, links and lateral locks.
