Brembo 2E5.5003A4 GT Rear BBK 316mm 2-Piston Gold Caliper Slotted for BRZ 86 WRX

Vehicle Fitment

• 2013-2021 Subaru BRZ (ZC6, All Trims)
• 2013-2016 Scion FR-S (ZN6, All Trims)
• 2017-2021 Toyota 86 (ZN6, All Trims)
• 2015-2021 Subaru WRX (VA, Manual Parking Brake Models Only)
• 2022-2026 Toyota GR86 (ZN8, All Trims) - see Fitment Notes

Fitment Notes

• Does not fit any Subaru WRX equipped with an electronic parking brake (CVT-equipped models) - manual parking brake WRX models only.
• Does not directly fit the 2022-2026 Subaru BRZ (ZD8) without modification; the Gen 2 BRZ uses an aluminum front knuckle with a protruding boss that blocks the caliper bracket. Modification or alternate bracket required for ZD8 fitment.
• 2022-2026 Toyota GR86 retains a steel knuckle and is confirmed compatible with this kit; wheel clearance must still be verified before installation.
• Aftermarket wheels are required - OEM stock wheels on most trims will not provide adequate clearance for the 316mm rotor and 2-piston caliper. Verify clearance using the Brembo wheel fitment diagram from Race Technologies before purchasing.
• This is a rear axle kit only - covers both rear corners as a complete axle set.
• Fully compatible with factory ABS and traction control systems on all listed vehicles.

Features

• 316mm x 20mm high-carbon, 1-piece vented TY1 slotted rotors deliver significantly increased thermal capacity and swept area over factory rear rotors.
• Cast 2-piece axial-mount 2-piston calipers in gold anodized finish provide rigid, even clamping force on both rotor faces simultaneously, eliminating the flex of OEM sliding calipers.
• TY1 slotted rotor surface continuously sweeps the pad face clean, evacuates heat and gas buildup, and delivers sharper initial bite and more consistent pedal feedback.
• High-carbon rotor formulation enhances thermal stability, reduces NVH, and improves resistance to thermal cracking versus standard gray iron rotors.
• Corrosion-resistant rotor plating protects disc surfaces against rust and oxidation for lasting performance and appearance.
• Aluminum caliper body reduces unsprung weight by up to 40% versus comparable cast iron designs, improving suspension response and handling balance.
• Pre-assembled and pre-bled at the factory - no bench bleeding required and installation is straightforward with all included hardware.
• Available in matching Black (2E5.5003A1), Red (2E5.5003A2), and Silver (2E5.5003A3) caliper variants; cross-drilled rotor version available as 2E4.5003A4.

Product Description

The Brembo 2E5.5003A4 is the Gran Turismo rear big brake kit in gold for the Subaru BRZ, Scion FR-S, Toyota 86/GR86, and manual-parking-brake Subaru WRX. Sharing the same 316mm x 20mm TY1 slotted rotor and 2-piston caliper specification as the rest of the GT-2E5.5003A family, the gold finish adds a visually distinctive look through the wheel while delivering the same performance advantages - greater thermal capacity, more consistent pad contact, and a firmer, more linear pedal feel versus the factory sliding rear caliper setup.

Fixed 2-piston calipers apply even force to both sides of the rotor simultaneously, eliminating caliper flex and promoting uniform pad wear. The TY1 slotted rotor surface continuously refreshes the friction interface, wiping away gas and pad debris with each rotation. The kit ships pre-assembled as a complete axle set with Goodridge-sourced stainless steel braided brake lines, CNC billet caliper adapters, and all installation hardware - bolting to the factory suspension with full ABS and traction control compatibility. Aftermarket wheels providing adequate clearance for the 316mm rotor are required; buyers should verify clearance using the Brembo wheel fitment guide before ordering.
