Show original supplier description
The Kartboy Big Brake Adapters V2 provide a solution for fitting more powerful 2-pot FHI or gold Brembo rear brake calipers to your Subaru. If you've acquired these upgraded calipers but found they don't directly bolt onto your stock backing plates, these adapters bridge that gap. The kit includes gold bolts, specifically noted for their use with Brembo calipers, ensuring proper hardware for the installation. These adapters are specifically designed for a range of Subaru models, including the Impreza from 1998-2007, WRX from 2002-2005, Legacy from 2000-2009, and Forester from 2000-2008. Ensuring your vehicle falls within these year ranges is crucial for proper fitment and to achieve the enhanced braking performance offered by the 2-pot caliper upgrade.
