For Autocross & Track Days, some customers run a 'square' setup; the same size wheels and tires, front and rear:
- All four corners: 20x10" wheels with a +23mm offset; and 285/30-20 (for lowered cars) or 275/40-20 (on stock suspension) tires all around
Possible 2016 SS wheel sizes:
Front wheels: 20x8.5" +25mm offset, Rear wheels: 20x9.5" +39mm offset
How does Offset and Backspacing work? A quick note:
the more "Positive" Offset the wheel has, the more "tucked under the car" the wheel will be mounted.
Negative Offset (or less + Offset) makes the wheels stick out farther from the car.
