Product Details

The EBC S9KF1221 S9 Brake Kit combines EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors for a complete, performance-focused brake upgrade. Purchasing this kit saves approximately 15% compared to buying the pads and rotors separately.

The S9 Kit improves upon the S5 Kit by pairing Yellowstuff pads with USR fine-slotted rotors, which are engineered to reduce wind noise during operation — a common characteristic of more aggressively drilled or slotted rotor designs.

Kit Contents:

  • EBC Yellowstuff high-friction brake pads — GG-rated for maximum stopping power
  • Fully shimmed, chamfered, and slotted pad design for optimal rotor contact and noise reduction
  • EBC's patented Brake-In coating applied to pads for faster seating and reduced bedding-in time
  • EBC USR sport slotted rotors — fine-slot pattern minimizes wind noise while improving bite and pad degassing
  • Caliper lubricant included

EBC Yellowstuff pads deliver a GG friction rating, making them one of EBC's most aggressive street and performance compounds. Combined with the USR slotted rotors, this kit is well-suited for drivers seeking confident, high-performance braking on spirited street driving or light track use.

Wow, super fast shipping and the best prices!

Quick and easy. Just hope it fits my car.

It was very quick and easy and I appreciate the 2nd day air shipping option.

Love autoplicity

Right item, right price !

Quick and Easy

Inventory is easy to use and I was able to find what I was looking for with no problem at all. Not only that, Autoplicity had what I was looking for for the cheapest price I could find anywhere else. $50 cheaper than any store I walked into, and cheaper than any other web site i looked at.

great selection

Easy peasy lemon squeezie

So far, so good. Best price I found. Very reasonable shipping. Parts were loose packed and rattled around a bit but nothing damaged. The hole for the EGR in the header was just a small hole and I had to drill it out. There were no instructions or any do

so far so good

Excellent transaction, received item very quickly and it was a lot cheaper than any other online retailer that I was able to find, could not even find cheaper on e bay.
