Sold in sets of 4 pads (front set or rear set). These are the "new and improved" HP Plus brake pads.

Hawk Performance's HP Plus brake pad compound is ideal for Autocross and Track Day drivers looking for a high performance race compound that can take the heat of the track and get you home safely without having to change the pads.

HP Plus utilizes a unique Ferro-Carbon, high-tech friction material that was developed and manufactured for sport driving in autocross, Solo II and "track day" applications. The Ferro-Carbon formulation offers lower wear rates and higher torque values than other competitive materials.

Extremely high coefficient of friction makes HP Plus the perfect upgrade over stock for high performance streetcars used in autocross competition or that experience repetitive, heavy braking.

Key Features:

• Designed to have extremely high friction output - the highest of any normal Hawk brake pad.
• Fade resistant.
• Worthy for Autocross & Club Racing events.

All Hawk Performance HP Plus / Autocross brake pads provide a limited lifetime warranty, ensuring products to be free of defects from manufacturer's workmanship and materials.

Notes on Friction: Due to the dramatic friction levels produced by this product to achieve "race-level" braking, rotor wear, noise, dust, and pad life may be affected.

Notes on Applications: If an application references ABS (Anti-lock Braking System), then you need to check if your BMW 4 Series has ABS. The easiest way to tell is by opening your hood and checking for a metallic box with a lot of metal lines coming out of it. This is the ABS unit. Also, for applications that reference rear brake pads, please check to make sure you have rear discs, not drums. To avoid brake imbalance, do not just upgrade the rear pads (purchase the front pads also).

Important Notes: For all new Hawk brake pads, we recommend following Hawk's Bed-In Procedure for maximum performance, which can be found in the brake pad instructions.
