Were going to have to save this upgrade for later. I ordered pads and rotors last night.
I did a lot of research and it appears the C4 set up really isn't that bad especially if your running a lighter car. It appears that they were prone to spreading and the way to tell if your caliper has spread is the the pad will wear at an angle from front to back or back to front.
There are also C4 calipers that were not prone to spreading because of the way they were cast. The C4 calipers from Baer(which are the ones I'm using) are not prone to spreading(from what I read) but if they are I will find out shortly because the pads I was using had such a strong bite I can hear and feel the rotors screaming for mercy not to mention the heat checking in them that I had never noticed before.
As far as rotors go I had talked to a guy at the NASA event that told me that he had gone to a Stop Tech rotor that had been treated through a heat and cold process among other treatments(don't remember the exact details) and that these rotors withstood major abuse with no heat checking and for my car through tire rack were only $127 a pop. That is a great price. Not sure how many of you have shopped race rotors but I have seen them from $650 and up.
