What makes the EBC USR slotted rotors different?

The USR rotors feature a fine-slotted pattern precision machined from unique EBC rotor alloys. These slots help to dispel gases and debris that build up during braking, which can lead to quieter operation and a more consistent pedal feel.

What is the benefit of the Yellowstuff brake pads?

Yellowstuff pads are made from a specially designed softer compound. This compound is intended to provide an improved pedal feel, particularly at lower speeds, and also contributes to a longer lifetime for the pads themselves.

Does this kit include everything needed for the rear brakes?

Yes, this S9 kit is designed for rear fitment and includes both the USR slotted rotors and the Yellowstuff brake pads for your specified Porsche models. The rotors are vented and have a 299mm diameter.
