Don't Forget The RestRemember, the laws of physics state that an object in motion tends to stay in motion, especially if it's a steel car pushing 4,000 pounds. So if your B-body isn't already equipped with disc brakes, it's probably a good idea to convert it. Fortunately, companies like Master Power Brakes have kits for most B-body Mopars. If cheap is more your style, you can still find A-body disc brakes and spindles on cars in salvage yards that will bolt onto your B-body and work way better than drum brakes. Also, don't forget the rest of the suspension. Upgrades here can lighten your car as well as improve acceleration, braking and handling, and ride quality.
