Suggested price For the V6 FRPP is 1100 from Ford for the 2010. It is supposed to work with 2011 with an extra part or 2 for the front Struts

But truthfully, unless they have rebuilt the LA freeway system I would stick with the 18 inch tires.
And my Stock 2010 Mustang does pretty good with just the stock suspension. Lowered, new struts and stocks and different Sway bars in the Spring.

 

Thanks for all the info. May just go W/ an auto and work from there.

 

I was hoping the get the PP with my V6 auto too. As other have said, get the 3.31 rear axle ratio.

 

Maybe ford will let us order one or two etc.

 

Don't hold your breath waiting for that...
