Product Description

The EBC S4KF1346 is a Stage 4 front brake upgrade kit pairing Redstuff ceramic pads with USR fine-slotted rotors, engineered for performance-oriented Nissan and Infiniti platforms including the 370Z, G37, Q50, Q60, Q70, M37, M56, and FX50. Redstuff's ceramic and aramid fiber compound cuts brake dust by up to 90% compared to OEM, delivers 20-25% more stopping power from cold, and handles repeated hard braking without fade - making it ideal for spirited street driving and premium import owners who demand clean wheels without sacrificing performance.

The matched USR slotted rotors are precision-machined from G3000 gray iron to EBC's exacting British standards. Narrow multi-overlap slots expel heat, water, and friction gas while promoting flat, parallel pad wear throughout the life of the kit. The thermic black anti-rust coating protects the rotors and wears away naturally in the pad-contact zone during bedding. This kit installs directly in place of factory front hardware with no modifications required, and includes caliper lubricant for a complete, professional install.
