If you're looking to upgrade your classic ride, the Baer SS4 rear brake system for the '65-'66 Ford Mustang is a solid choice. This setup comes with a robust S4 4-piston caliper paired with a 12-inch one-piece rotor that's both slotted and drilled, giving you that extra bite when you need it. The zinc plating not only looks good but helps fight off rust too—always a plus for us enthusiasts.
One of the standout features here is the billet backing plate. It's not just a pretty face; it serves as the caliper mount and houses the Banksia 1-piece park brake assembly. This is a big deal because it’s a more efficient design compared to the old-school drum-in-hat systems. Plus, it uses the same shoes as the later model Corvette C5/C6, making replacements a breeze.
Now, let’s talk about fitment. This system is designed specifically for '65-'66 Mustangs with either a 9-inch Ford rear small bearing housing or an 8-inch Ford rear with a standard bearing housing. So, if you’ve got one of those, you’re in luck!
