What makes this motor mount different from the original rubber ones?

This mount is made from Hyper-Flex polyurethane, which is more resistant to wear and tear from engine movement and under-vehicle fluids than standard rubber. It's designed to last longer and handle more stress, whether you're driving on the street or at the track.

Will this mount cause a lot of vibration in my car?

While it's built for performance, this mount is designed to be soft-running enough to absorb vibrations for street use. It aims to balance performance needs with comfortable daily driving.

Does this motor mount come with any hardware?

This motor mount is sold individually and typically does not include installation hardware. You may need to reuse your original hardware or purchase new components separately.
