Keep in mind, this is an odd size- and the CF requires Z rated tires.

This makes your choices limited. The Michelins on some CF are the better of the two for traction/handling in non-snow areas. The Continentals on other CFs are an all-season tire that are capable in snow areas but give up a bit in handling. I would suggest looking on www.tirerack.com for prices. I would also suggest not letting anyone without the special tire machines needed for these low-profile tires touch your car. It is a difficult tire to mount, and one little slip could cost you $500 for a new rim, or damage the tire, or sensor.
