The Brembo GTR front big brake kit for 2002–2021 Subaru WRX is a front-specific upgrade with 6-piston billet calipers and two-piece 350x34mm rotors finished in nickel and slotted Type 3. The slightly larger 350x34mm two-piece rotors provide the braking surface specified for WRX applications across the listed years as a direct front brake replacement.
