Product Description

The EBC S13KF1668 Stage 13 front brake kit is a performance-oriented upgrade designed for Subaru WRX and WRX STI platforms. It combines EBC Yellowstuff high-friction brake pads with RK OE-style vented rotors to deliver improved stopping performance, higher thermal stability, and more consistent braking behavior compared to factory components.

Yellowstuff pads are engineered for strong initial bite and stable friction under high-temperature conditions, making them suitable for spirited street driving and occasional track use. The Geomet-coated rotors resist corrosion while maintaining smooth, balanced braking performance through repeated heat cycles.

This kit is intended for direct front axle replacement on compatible Subaru WRX/STI models with matching OEM brake specifications. Proper rotor verification and bedding-in are required to ensure optimal performance, pad transfer layer formation, and long-term durability.
