Bring Modern Six Piston Stopping Power To Your Classic Mustang
Factory drum and early disc brakes on a 1965-1969 Mustang were never designed for todays driving demands. The Wilwood 140-12947-D front hub kit replaces the original setup with forged Dynapro 6 billet calipers and 12.19in drilled and slotted rotors, giving your classic pony car the pedal feel and fade resistance of a modern brake system while keeping a period-correct look.
Key Features

- 12.19in diameter SRP drilled and slotted rotors in black electro coat finish
- Direct bolt-on fitment for factory disc or drum front spindles
- Dual 5 x 4.50in and 5 x 4.75in bolt pattern hubs for wheel compatibility
- Aluminum hub construction with a plus .09in hub offset
- Dynamically balanced rotors for smooth, vibration-free operation
- Fits most 15in diameter wheels and larger
