Get the Centerforce and Fidanza Combo.. a match made in heaven, NO DAMN annoying Chatter to hear of.. and Awesome GRIP!
your best bet for a Centerforce DF is NOPI for something like 430 shipped..
I can get you the Fidanza for 375 shipped.
Unless your doing the 3L Turbo I'd get the Centerforce.. I have had it for about 5000 miles with NO PROBLEMS, NO NOISES

whatsoever... and yes.. I do USE it bigtime to its full capabilities.
