So, some time ago, I did some research on converting the SSEIs brakes to the GXPs larger ones on the front and rear. The fronts are coming right along with the 12.7" GXP Dual Piston Brakes from ZZP. The rears are giving me trouble. I was told that all the rear calipers are the same across all the platforms, and will just need a bigger bracket to fit larger rotors. So, I purchased the ZZP Cross Drilled and Slotted GXP 12" brakes for the rears, but with a bigger bracket or not, I don't see how this would work. I am going to return them, and get the normal ssei single plated brake rotor for the rear now, but before i do, has anyone ran into this problem? Has anyone made the conversion already? If so, how?

And also, how to do you upload pictures? From my library, i mean.

Not sure what ZZP has, maybe it's a W-body(Grand Prix, Impala, Regal) specific brake set.

All you need to upgrade is the caliper bracket, and the larger rotors.

So, the rotors I bought were gxp 12" but they came as dual plated rotors. So, I what you are saying I need to do is just find larger single plated rotors? And would you happen to know where I can acquire the larger brackets?
