EBC GD1321 slotted and dimpled brake discs are a proven fast-road and track-day upgrade for the Subaru Impreza GD chassis - specifically the GT and STI models. They’re not OEM replacements; they’re engineered for higher thermal capacity and consistent pedal feel under repeated use.
UK-machined, R90-certified blanks with silver corrosion protection
Wide-aperture slots + dimples aid pad degassing and water clearance - ideal for UK weather and spirited driving
No through-drilling means no crack propagation; better longevity than drilled alternatives
Third-generation GD Series design: refined cooling and uniform pad wear
