Fitment Notes

• Rear rotor position only. Does not replace front rotors.
• Sold individually. Order 2 for a complete rear axle set.
• Double-drilled hub accommodates both 5x100 and 5x114.3 bolt patterns (-10 suffix).
• Does not fit Subaru BRZ models equipped with factory Brembo brakes. Verify your trim before ordering.
• Toyota 86 GTS spec uses this rotor. Confirm fitment for GT models separately.

Features

• XS Gold premium cross-drilled and slotted pattern - combines slot benefits with drilled holes for maximum friction dust and gas evacuation
• Double-drilled hub design fits both 5x100 and 5x114.3 bolt patterns for broad cross-platform compatibility
• Built on the 4000 Series platform with Thermal Stability Profiling (TSP) for improved heat resistance and structural durability
• Patented Kangaroo Paw ventilation - 144 diamond and teardrop pillars deliver up to 20% better cooling than straight-vane designs
• XG-150 high-carbon alloyed iron construction for superior resistance to warping and thermal fatigue
• CBN (Cubic Boron Nitride) machine-turned friction surface for precision disc thickness variation (DTV) control
• Thermographic Heat Paint (TGHP) markings for real-time visual monitoring of rotor temperature and fatigue
• Anti-rust coating on all non-friction surfaces for a cleaner, longer-lasting finish

Product Description

The DBA DBA42663XS-10 is a 4000 Series XS Gold rear brake rotor engineered for a wide range of Subaru and Toyota platforms sharing the 290mm rear rotor specification. Its double-drilled hub (5x100 and 5x114.3) makes it a true multi-platform solution, covering the Subaru WRX, BRZ, Legacy GT, Outback 3.6R, Scion FR-S, and Toyota 86 in a single part number. Cast from XG-150 high-carbon alloyed iron and processed through Thermal Stability Profiling, this rotor is built to withstand repeated performance stops without the warping or fade common in lower-grade alternatives.

The XS Gold pattern combines cross-drilled holes with CNC-machined slots to maximize gas and dust evacuation from the pad surface, delivering sharper initial bite and more consistent pedal feel. Kangaroo Paw ventilation pillars keep temperatures in check during spirited driving, while Thermographic Heat Paint gives drivers a clear visual indicator of peak braking temperatures. Ideal for daily performance use, canyon driving, and light track duty on the ZN6/ZD8 and GR/GH platforms.
