Brembo 08-14 WRX STI Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Silver

This is the Brembo Rear GT Big Brake Kit for your 2008-2014 Subaru WRX STI. It's a serious upgrade for the rear brakes, featuring a four-piston caliper and a two-piece, 345x28mm drilled rotor designed to handle the demands of spirited driving and track use. If you're looking to significantly improve your car's stopping power and heat management, this kit is a solid choice.

The calipers are cast aluminum, which keeps weight down while maintaining strength. They're paired with a two-piece rotor construction, where the rotor disc is separate from the hat. This design allows for better thermal management, as the aluminum hat can dissipate heat more effectively than a solid, one-piece rotor. The rotors themselves are drilled, which helps to vent gases and heat away from the pad surface, leading to more consistent braking performance, especially under heavy use. This kit is designed to be a direct fit for the specified WRX STI models, simplifying the installation process compared to custom setups.

When installing a big brake kit like this, it's always a good idea to consider upgrading your brake fluid to a higher temperature rating, such as DOT 4 or higher, to take full advantage of the kit's capabilities. You'll also want to ensure your brake lines are in good condition, as they can expand under pressure, which can reduce pedal feel. This Brembo kit is a well-built system aimed at providing improved stopping performance and durability for your performance Subaru.
