72 Cutlass Brake Upgrade Options
I have a 72 Cutlass that was a factory drum brake car. At some point in its past was upgraded to front disk brakes. My goals for the car are a mild pro-touring inspired build for street use (might attend some random track night in america events or something). 17x9 wheels have been purchased and am thinking of brake upgrades in the future and am looking for some insight.
Front:
Seems the CPP C5 upgrade is a good value to get some larger rotors/calipers. Best I can tell the spindle should work with stock or aftermarket arms, I have BMR front uppers (not installed yet) and plan to pick up the lowers as well. Ebay browsing doesnt seem like i could do any better piecing a kit together with c5 calipers, drum brake hubs etc. and I dont want to spend money on the big kits at this time. Going with the wilwood d52 calipers for now almost brings the cost up to the kit.
Could the CPP front kit work with existing master/booster/rear brakes until i upgrade the rear as well as after rear is upgraded?
Rear:
Currently factory drum, looks like 98-02 Camaro rear backing plates/brakes work on the a-bodies but I have seen some brake kits mention differences with oldsmobile and other rear ends. What is needed to make these work on an olds rear?
Trying to plan out my build. Front will be BMR upper and lower arms with tall upper and lower ball joints. Currently on 1" lower spings I believe but will be going lower.

I'm in a similar boat (68 Cutlass). I've been planning my upgrades for almost 2 years now, but keep getting derailed by other things.
One thing I came across in my research is feedback about the CPP spindles including bad geometry and poor tech support. A member called HWYSTR455 on the maxperformanceinc website posted his experience. That convinced me that I'll be going a different route.

Thanks for the reply on that. I was not able to find any reported issues but also couldnt determine how or if geometry was changed with them. Guess I will stick with stock spindles and tall upper/lower ball joints.
I came across a youtube video of someone using stock drum hub with c3 rotors? and c5 calipers and brackets from cpp. doesnt look like that is a kit anymore but I could probably fab some brackets. Are the drum and disk spindles different?
