Your options are 1 piece polished or a 2 piece rotor. I do know off the top of my head that the PM 2 piece rotors and our HogPro 2 piece rotors will not fit on stock wheels. 1 piece rotors are polished stainless, 2 piece consist of an aluminum carrier that is either chromed or anodized and then contrast cut. The reason the 2 piece don't fit on the stock wheel is due to the diameter and counterbore of the rotor in relation to the stock wheel. On aftermarket wheels this is not an issue as the hub is a separate piece that takes this counter bore into account.

 

That is exchange stock for polished stock.
