blackbirdcustoms vs. impala ss rear brake kit

[jlaird]

I've narrowed my rear brake conversion to these two options. Are one of these setups more "heavy-duty" than the other? I'm going to be running large diameter wheels, so I want the better of the two if there is a difference. It's kind of hard to compare because you don't know what is in the blackbird kit until after you buy, but he did tell me the rotor is 1 1/4 thick which is thicker than any rotor in one of these rear break conversion kits that I have seen. Maybe somebody that has purchased his kit can chime in.
