- Performance gearbox mounts are available as aftermarket upgrades or standard replacements for Porsche vehicles.
Benefits of upgrading or replacing Performance Gearbox Mounts for your Porsche:
Enhanced shifting precision: Performance gearbox mounts minimize transmission movement, resulting in improved shifting precision and accuracy, especially during high-performance driving.
Reduced drivetrain slack: Upgrading to performance mounts helps minimize drivetrain slack, ensuring quicker power delivery and smoother gear changes, leading to enhanced driving dynamics.
Improved throttle response: By reducing transmission movement and improving rigidity, performance mounts provide quicker and more precise throttle response, enhancing overall vehicle responsiveness.
Enhanced stability and control: Performance gearbox mounts contribute to improved stability and control, especially during aggressive acceleration and high-speed cornering, reducing transmission-induced weight transfer.
Reduced noise, vibration, and harshness (NVH): Stiffer gearbox mounts help reduce transmission-related vibrations and noise, resulting in a smoother and more comfortable driving experience.
