STI heavy duty drivetrain mounts feature increased rubber hardness to reduce driveline movement and torque reactions. This improves power transfer and increases reliability under extreme use. Essential for cars with increased power outputs. These mounts are produced on the same production line as factory parts and share same rubber molds but they are not standard factory parts (not even on STI models). We sell only genuine STI mounts imported from Japan.
Usually ships in 1 to 2 weeks.
What is the difference between this part and my original factory one? The rubber durometer (hardness) is noticeably increased. Otherwise they are identical to the original parts.
What are the benefits of the heavy duty drivetrain mounts? The harder rubber limits drivetrain movements which enhances throttle response and increases reliability under hard launching and shifting.
Are there any downsides to using this product? The increased rubber hardness will transmit more engine vibration and gearbox noise to the chassis. However, it is generally still considered tolerable for daily driver applications.
