There are only one set of springs for xi's: 145/460.

The extra weight is why they went with the "sport" spring rates, and not the regular spring rates. Also, due to the front geometry being reworked to accomodate the axle, the motion ratio is a little higher, thus increasing the wheel rate while not increasing the actual spring rate.
