I am looking into getting a 4 wheel disc brake system for my Charger, I will do the XV level 1 setup when I do the brakes as well. I want something that can stand up to a track day here and there but it will be 90% street car, and I want a parking brake if that matters. I also plan on running 17-18" wheels most of the time, but would like to be able to fit an 15" slick on the back for trips to the strip. Any advice is appreciated. I would also like to get everything as a kit if possible, once I decide on brakes I wil figure out what master works best with them but really like the hydroboost setup. FYI-It has manual 4 wheel drums now but want to redo the entire system, 4wheel drums=scary in city driving.
