Show original supplier description
The STI Mission Mount is a performance-oriented upgrade for the chassis and body, featuring increased rubber bushing and mount hardness. This design effectively suppresses elastic deformation, which reduces losses in power and torque transmission and delivers a more immediate response for steering and throttle inputs. It is specifically targeted toward owners who participate in sports driving or competitive motorsports such as one-make racing and gymkhana. It aims to provide sharper throttle response, more precise gear engagement, and enhanced power transfer by minimizing unwanted flex and elastic deformation. The result is a more connected driving experience where drivers can feel every shift and throttle input more directly. While the increased hardness provides significant performance benefits, it is important to note that vibration and noise may be increased during regular driving. This is a normal trade-off for the enhanced responsiveness and a more engaged feel behind the wheel. Professional installation is recommended for optimal results, especially when combined with other drivetrain modifications. Always verify fitment for your specific model year and configuration before installation.
