Description

The Cusco Master Cylinder Brace is engineered to improve brake pedal feel and responsiveness for 2015-2021 Subaru WRX and STI models. By stiffening the firewall around the master cylinder, this brace significantly reduces flex during heavy braking, resulting in a firmer and more confident pedal. This enhancement is particularly beneficial during spirited driving or track use, where precise brake control is crucial. Constructed from high-strength metal and finished for corrosion resistance, this brace is built for durability and long-lasting performance. Its direct-fit design ensures a straightforward installation process, typically requiring only basic hand tools and no permanent modifications to the vehicle. This makes it an accessible upgrade for Subaru enthusiasts looking to achieve better brake modulation and pedal feedback. While the product is generally an easy installation, some users with larger hands have noted that the space in the engine bay can be tight. Installation may be more challenging if a strut tower brace or front-mount intercooler is already installed, potentially requiring removal or adjustment of these components. The use of specialized tools like wobble sockets and techniques such as using tape to hold bolts can aid in the installation process. The product fits 2015-2021 Subaru WRX and 2015-2021 Subaru STI models.
