DIXCEL Rear Brake Rotors - Subaru WRX tS/Club Spec (VB) Brembo / WRX STI (VA) - 326x20mm
Upgrade your Subaru WRX or WRX STI's rear braking performance with Dixcel brake rotors, engineered in Japan and developed through decades of OEM supply and motorsport experience. Dixcel rotors are designed to deliver consistent braking performance, stable pedal feel, and reliable control for daily driving through to more spirited use.
This listing covers the Dixcel brake rotor types shown for the Subaru WRX STI (VA) fitted with factory Brembo rear calipers, and the Subaru WRX (VB) models equipped with factory Brembo calipers including the 2024 WRX Club Spec and 2025 WRX tS Spec B, all using 326x20mm rear rotors. This rotor also suits VB WRX owners who have completed an OEM STI Brembo caliper swap. If your VB WRX is running the factory single-piston sliding calipers, this rotor is not the correct fitment β please check the standard VB WRX listing instead. Multiple rotor types are available, ranging from street-focused replacements to higher-performance applications. Use the product options on this page to select the rotor type best suited to your driving style and vehicle configuration.
