Hi, Guest
the only difference betweem ST and SVT is the caliper brackets and rotors. if you want to do the upgrade, then thats all you need plus your pad of choice to replace OEM.
I suggest simply doing a full upgrade, for the main reason that the brackets are upwards of 250$ from a dealer EACH at wholesale price when SVT kit comes with rotors, pads and everything else for less, then you can see off your ST rear discs and make a turn around for your self.
^^ for rears only.
