Make no mistake about it, most classic car enthusiasts like to go fast. We spend countless hours in the garage figuring out ways to go faster. Adding more horsepower guarantees you’ll impress your buddies and have a blast every time you pull away from a red light, but that extra giddy-up can cause some problems too. Every time you play a little at a red light, the next stop light shows up faster than it used to. You could try cruising in a different part of town, but where’s the fun in that? The bottom line is simple—that extra horsepower may require a brake upgrade to maintain safety.
