Show original supplier description
The STI ENGINE MOUNT RH (ST4100055110) is a performance-oriented engine mount specifically designed for the Subaru Impreza 4DooR (GD). Constructed with hardened rubber on the power unit's mounting points, this mount effectively reduces vibrations compared to standard components. The primary benefit is an enhanced driving experience through improved throttle response and a more direct, precise shift feeling. This makes it a popular choice for enthusiasts seeking to optimize their vehicle's performance. However, potential buyers should be aware that installing this product may increase vibration and noise within the car's body. The product is explicitly noted as being "for competition only." Additionally, the product explanations provided are based on Japanese specifications, which may differ from regional standards. This mount is compatible with the Impreza 4DooR (GD). Other compatible vehicles mentioned in search results include various Impreza, WRX, Legacy, and Forester models from different model years, though direct fitment should always be confirmed.
