Product Description

The EBC GD1511 Turbo-Groove rear brake discs are a direct, high-performance replacement for Subaru WRX and STI models spanning from 2007 through 2017 (GR/GV), as well as 2008-2019 Impreza WRX/STI variants. Engineered with wide full-sweep V-slots and blind dimple holes, these discs efficiently vent hot gases, dirt, and water, maintaining pad contact and reducing fade under hard driving conditions. Unlike drilled rotors, the blind-dimple design preserves structural integrity, minimizing the risk of cracking during spirited use or occasional track work :contentReference[oaicite:1]{index=1}.

Constructed from OE-spec G3000 cast iron and precisely balanced to OEM standards, the ventilated 316 mm discs handle sustained heat up to ~900 °C, offering consistent braking performance. The zinc/black coating protects unclad areas from corrosion without affecting friction surfaces. Certified with ABE/EU-type approval, they fit directly onto the stock Brembo rear calipers using the 5x114.3 mm bolt pattern, requiring no adapters or modifications :contentReference[oaicite:2]{index=2}.

Supplied as a matched pair, the GD1511 is ideal for rally-style enthusiasts or street drivers seeking enhanced cooling, reduced pad glazing, and improved longevity over plain rotors. Installation is straightforward - swap into the stock rear assembly for immediate upgrade in performance and braking response.
