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

The USR fine-slotted rotors are designed to help clear dust and gas away from the pad surface, which maintains consistent braking performance. They also feature a fine slotting pattern specifically engineered to reduce wind noise during operation.

What does the EBC Brake-in coating on the pads do?

The patented Brake-in coating on the Yellowstuff pads helps them seat quickly and effectively to the new rotors. This process ensures you get optimal braking performance sooner after installation, reducing the break-in period.

Does this kit include everything needed for installation?

Yes, this kit includes the EBC Yellowstuff brake pads, the USR sport-slotted rotors, and caliper lube to assist with the installation process. It is designed as a direct replacement for your stock components.

Product Details

If you're looking to get the most out of your 1998-2003 INFINITI QX4's braking system, this EBC S9 Brake Pad and Rotor Kit is a solid option. It bundles together EBC's flagship GG-rated Yellowstuff high-friction pads with their USR sport-slotted rotors, giving you a significant upgrade over stock components. This kit is designed as a direct fit, meaning no modifications are needed to install it over your existing setup.

What sets this kit apart is the combination of high-performance pads and rotors. The Yellowstuff pads are known for their strong initial bite and fade resistance, making them suitable for both spirited street driving and track use. Paired with the USR fine-slotted rotors, you get improved brake cooling and dust/gas clearing, which helps maintain consistent stopping power even under demanding conditions. The USR rotors also feature a Geomet anti-rust coating to protect them from corrosion, and the fine slotting pattern is designed to reduce wind noise compared to more aggressive slot designs. EBC even includes their patented Brake-in coating on the pads, which helps them seat quickly to the rotors for optimal performance right away, and they throw in caliper lube to help with the installation.

This kit is a comprehensive solution for anyone wanting a noticeable improvement in braking performance. You're getting the pads, rotors, and necessary lube all in one package, often saving you about 15% compared to buying each part separately. Just remember that while these are great for track days, EBC does not offer a warranty for race use.
