Fitment Notes

• Fitment is exclusively for vehicles equipped with the OEM 2-Pot Brembo rear caliper. Do not fit to vehicles with non-Brembo (standard) rear calipers - a different pad number applies.
• Subaru WRX STI GDB fitment: applies to 2001-2007 (GD chassis) with factory Brembo rear caliper only.
• Nissan Skyline R32 GTR fitment: applies to V-Spec and V-Spec II models with factory Brembo rear calipers only. The base R32 GTR uses Sumitomo rear calipers and does not fit.
• Nissan 350Z fitment: applies to Track and Grand Touring Brembo-equipped variants. Verify rear caliper type before ordering.
• Replaces superseded DBA part number DB1521.
• Due to multiple brake packages available within the same model year on some platforms, DBA recommends measuring existing pad dimensions and comparing against DBA's published pad shape diagrams before ordering.

Features

• Semi-metallic, carbon fibre-enhanced friction compound delivers high initial bite and consistent friction from cold temperatures through to extreme heat - ideal for the demanding rear brake loads on high-performance AWD and RWD sports cars.
• G-G Class Friction rating (0.45 average mu from low to high temperatures) provides a substantial step up in stopping force compared to OEM Brembo pads across the full thermal spectrum.
• Optimal braking consistency maintained up to 550°C (1022°F), making these pads well suited for club track days, spirited canyon runs, and street performance use on Brembo-equipped performance vehicles.
• Application-specific slots machined into the friction face continuously vent heat and evacuate friction dust and gases during braking, maintaining consistent pad bite and preventing glazing.
• Post-curing (scorching/TSP) process applied at the factory raises cold friction effectiveness out of the box and shortens the bedding-in period significantly compared to uncured pads.
• Carbon fibre, low-copper formulation is NSFI certified, reducing the environmental impact of brake dust without compromising performance.
• Application-specific multi-layered elastomeric coated NVH shims are included, reducing brake squeal and vibration for improved daily driving refinement alongside track performance.
• Direct bolt-on fitment - no modification to Brembo calipers, brackets, or hardware is required on any listed vehicle.
• Engineered for pairing with DBA 4000 Series or 5000 Series T3 slotted rear rotors for maximum system performance and heat management.

Product Description

The DBA DB1521XP Xtreme Performance rear brake pads are purpose-built for the OEM 2-pot Brembo rear caliper shared across some of the most iconic Japanese performance cars ever produced - including the Subaru WRX STI (GDB, GRB, VAB), Mitsubishi Lancer Evolution IV through X, Nissan Skyline GT-R R32/R33/R34, and the Nissan 350Z in Brembo-equipped trim. Built around DBA's semi-metallic, carbon fibre-enhanced friction compound, these pads are rated to maintain consistent G-G class friction up to 550°C (1022°F), delivering significantly more stopping bite and heat tolerance than the OEM Brembo pads they replace. The post-curing (TSP) process applied during manufacturing elevates cold friction effectiveness immediately out of the box, which is especially valuable for drivers who go from cold street driving to aggressive track use without a lengthy warm-up routine.

Fitment is specific to vehicles equipped with the factory 2-pot Brembo rear caliper. This is a critical distinction - the DB1521XP is not compatible with non-Brembo (standard/Sumitomo) rear caliper variants of the same models. For example, on the R32 GTR, only V-Spec and V-Spec II models came from the factory with Brembo rear calipers; base R32 GTR models did not. Similarly, on the Nissan 350Z, only Track and Grand Touring variants with Brembo rear calipers are compatible. Buyers should verify their rear caliper type before ordering. The superseded predecessor DB1521 is a direct replacement reference confirming this is a well-established, long-running pad shape that fits across a wide range of iconic platforms.

Application-specific slots in the friction face work continuously to evacuate heat, dust, and gas during braking, maintaining consistent bite across a full track session or a spirited mountain drive. The included multi-layered elastomeric NVH shims are tuned for this specific Brembo caliper application, keeping noise and vibration to a minimum for drivers who also use their vehicles on the street. For the best possible rear braking performance, DBA recommends pairing these pads with the 4000 Series or 5000 Series T3 slotted rear rotors, which are engineered to complement the XP compound and optimise heat management under repeated hard braking.
