Do they have reduced prices on their winter tires at certain times of the year?,also they mention that the Z may have "Locating Pins" on the hub and that these will need to be removed to use their wheels, has anyone had any experience with this?

 

The Locating Pins are one on each side on the front hub that is there to prevent stupid people from trying to put the rear wheels on the front of the car. You will see them when you take off the fronts and then just take them off.
