Tamago's guide to ultimate yaris handling

[turboyaris]

i gotta interject, as far as tire pressures and camber is concerned.... I would say you would be wise, in investing in a tire pyrometer. Longacre makes some basic models for 100-150$. This will allow you to take tire temps at the outer side/middle/ inner side and determine that if the middle is higher then the outer and inner side your tire pressure is too high and you need to reduce... Likewise, if the outer edge temp is higher then the inner edge temp, you want to add more negative camber. basically with this method, you get much easier quantitative data to help determine what to do.

As for using this with autocross, a quick little self made track, should get you enough data to setup your camber and tire pressures properly.


This process will get you theoretically ideal setup, however, if you need to compensate for another handling issue, then adding or subtracting camber or tire pressures may be needed.
