What is the main benefit of the USR slotted rotors in this kit?

The fine slots on the USR rotors help to sweep away dust and gas that can build up between the pad and rotor. This helps maintain consistent braking performance and also reduces wind noise compared to some other slotted rotor designs.

Do the Yellowstuff pads require a break-in procedure?

Yes, the Yellowstuff pads in this kit feature EBC's patented Brake-In coating. This coating helps to seat the pads quickly and effectively with the new rotors, ensuring optimal performance shortly after installation.

What is included in the EBC S9KF1146 kit?

This kit includes a complete set of front brake components. You'll receive the EBC Yellowstuff brake pads, the EBC USR slotted brake rotors, and a packet of caliper lube to assist with installation.

About this part

Product Details

If you're looking to get more stopping power out of your 2005-2010 Chevrolet Cobalt, this EBC S9 kit is a solid option. It bundles together EBC's popular Yellowstuff GG-rated brake pads with their USR fine-slotted sport rotors, giving you a complete front brake upgrade.

The Yellowstuff pads are known for their high friction compound, which means they grab harder than stock pads, especially when they heat up. Paired with the USR rotors, which feature fine slots to help clear dust and gas, you'll notice a more responsive feel at the pedal and improved performance during spirited driving or track use. The rotors also come with a Geomet anti-rust coating to keep them looking good, and the pads have a patented Brake-In coating to help them seat quickly with the new rotors. This kit is designed as a direct fit, meaning no modifications are needed over your factory setup.

This kit includes everything you need to get started: the front pads, front rotors, and even a packet of caliper lube to help with installation. Just remember, while these are great for street and track, EBC does not offer a warranty for race use.
