Description

The GrimmSpeed Pitch Stop Mount addresses the limitations of the factory pitch stop mount, which often allows for considerable engine and transmission movement during performance driving. This can lead to a less connected feel during hard acceleration, braking, and shifting. The GrimmSpeed unit is precision-machined from a single piece of billet 6061 aluminum for maximum rigidity while minimizing weight. It features a durable, heavy-duty anodized coating to withstand high heat and the elements, laser-etched GrimmSpeed logos, and is assembled with durable 80-durometer urethane bushings and stainless steel sleeves. This design significantly minimizes play between the engine and transmission, leading to a more stable and responsive driving experience, while aiming to maintain ride comfort. Key specifications include the use of billet aluminum for its strength and weight-saving properties, an anodized coating for longevity, and 80-durometer urethane bushings that provide firm support without creating an overly harsh ride. The mount is designed with a reversible installation, allowing the user to choose which logo faces upwards. This pitch stop mount is compatible with a wide range of Subaru models, including 2002-2023 WRX, 2004-2021 STI, 2002-2023 Impreza, 2004-2018 Forester, 2003-2012 Legacy, 2003-2009 Outback, and 2013-2023 Crosstrek. However, it is explicitly noted that this mount is *not compatible with automatic CVT models* for certain vehicle fitments. Installation is described as straightforward and direct. Many users report an immediate and noticeable improvement in vehicle stability and shifting precision after installation, with minimal or no added cabin noise.
