Product Description

Hawk Performance
Replace the weak factory brake pads on your 2015-2018 Mustang GT Performance Pack with this Hawk HPS 5.0 rear brake pad kit! The HPS 5.0 compound is great for ABS equipped Mustangs as it has just the right amount of torque. Too much brake torque and your ABS goes into ICE mode, too little and there is no improvement to the product. Pedal feedback, noise, brake torque and dust control was Hawk's goal with the High Performance Street 5.0 compound, and they delivered! Hawk's HPS 5.0 brake pads allow the driver to challenge themselves and their S550 with a new and unique driving feel! These pads are gentle on rotors while remaining virtually noise free!

HPS 5.0 Compound
Hawk HPS 5.0 brake pads are perfect for high performance street cars that's purpose is daily or weekend driving. While they will perform on the occasional track visit, their main purpose is a slightly more aggressive pad over stock applications.

Important Installation Instructions
All brake pads require a burnishing or bedding-in procedure in order to achieve optimal performance and durability. During the bedding-in process the pad conforms to the rotor surface and generates an import transfer film. Prior to installation, make sure the brake system is free and clear of debris, brake fluid is replaced and all brake components are properly installed and in good working order.

Fitment Note
Will NOT fit Shelby GT350.

4. Allow at least 15 minutes for the brake system to cool down.
5. After step 4 is completed, your new brake pads are ready for use.
