EBC S13KF1358 Yellowstuff Pad RK Plain Rotor Kit for 2015-2021 Subaru WRX 2.0T

Vehicle Fitment

• 2015-2021 Subaru WRX (Base, Premium, Limited, 2.0L H4 Turbo EJ257/FA20DIT, AWD)

Fitment Notes

• Front axle kit only - pair with a matching rear kit for balanced brake performance
• Does not fit 2015-2021 Subaru WRX STI - STI uses a larger 340mm front rotor (Brembo caliper)
• Does not fit 2022+ Subaru WRX (VB chassis) - uses different rotor dimensions

Features

• EBC Yellowstuff aramid-fiber pads deliver high friction from cold with zero warm-up required - ideal for spirited street and occasional track use
• Yellowstuff compound maintains strong, consistent bite even under sustained heavy braking and elevated heat
• Patented EBC Brake-In™ surface coating on pads accelerates bed-in after install for immediate safe performance
• Pads are fully shimmed, slotted, and chamfered for quiet, vibration-free daily operation
• RK Series rotors are precision-machined from G3000 gray iron to OEM specifications and 100% individually runout-inspected
• Thermic Black anti-corrosion rotor coating self-removes in the pad sweep area during the first few stops - no prep required
• Kit saves approximately 15% versus purchasing pads and rotors separately
• Includes caliper lubricant for proper installation and noise reduction

Product Description

The EBC S13KF1358 is a front brake pad and rotor kit built for the 2015-2021 Subaru WRX, pairing EBC's high-performance Yellowstuff aramid-fiber pads with OE-quality RK Series plain rotors. Yellowstuff is EBC's go-to compound for drivers who want strong, progressive braking from a cold start without needing a warm-up lap - making it equally effective for a hard daily commute or an autocross weekend. Unlike Redstuff (which targets low dust), Yellowstuff prioritizes maximum friction and heat resistance, gripping well even as temperatures climb under repeated hard stops.

The RK7337 rotors are cast from G3000 gray iron to OEM dimensions, balanced, and runout-inspected to ensure vibration-free braking out of the box. Protected by Thermic Black anti-corrosion coating, they install directly without any surface prep - the coating wears away naturally in the pad contact area during the first few stops. This kit is a direct-fit, no-modification upgrade for WRX owners who push their car harder than stock brakes are designed for, and want reliable, high-friction front-end stopping power to match.
