I know what it will take to get the calipers to work but I am trying to find someone that can make the bracket. There was a guy that had a BBK he built on performancetrucks.net. He used Baer Eradispeed 15" front rotors and 14" rear. He then used the Camaro SS calipers which he said was the same as the calipers from a Dodge Viper. The rear he used the stock Brembo rear calipers using a bracket he made. He ended up buying a Stoptech kit and sold the entire kit 15" and 14" rotors, Brembo calipers, SS brake lines and new pads for $2000 shipped. Believe it or not it took him a while to get it sold. I paid more than that for my front kit obviously and the only difference I saw really was my kit has 2 piece front rotors. I emailed him to see if he has the file still and if he wanted to make another set so I can throw them on mine. Like you I just want it to match aesthetically because I do not like having big brakes with big red calipers on the front and stock on the back. If I can get some brackets for the back I will pull the rear end apart and put the 4.11 gears rear diff and rebuild the rear axle hub to hub. I then I want to have the calipers powder coated blue and then flush the fluid. Ideally I would like to have the rear end narrowed since I am running the 20" GMC declad wheels widened 2.5" with 325/50/20 and 275/55/20 on the front. I did have 275/40 and 315/35 but the sidewall was too small and the tires weren't wide enough. It looked really good from the side with spindles, Viking DA coilovers, DJM rear hardware, Belltech 5305 coils, adjustable panhard, and Airlift bags. But the 275/55 and 325/50 fill the fenderwell so much better and ride better.
