What do you think the swap consists of? Chewing gum and duct tape?
You haven't done any modifications to your suspension or drivetrain, have you? You're replacing a lot more than "disc rotors", whatever those are. You're replacing the entire suspension. LCAs, UCAs, uprights, hubs, axles, etc.
Unless your engine is producing more torque than 4 lugs can handle, you're doing this swap for the wrong reasons.
