Engine mounts are subjected to be most underrated upgrade available. They are responsible for keeping the engine and transmission in place and at the same time serve to absorb the vibrations to increase the comfort. Engine mounts are also responsible for transferring power to the wheels. Lots of this power is often absorbed in the soft stock engine mounts.

Hardrace engine mounts are designed to reduce drivetrain movement under hard acceleration and cornering, allowing all the available power to be transferred to the ground.

Street engine mounts

Hardrace offers two types of engine mounts, the so called street engine mounts and race engine mounts. The difference between the two of them is the durometer. While at the track, you care the least about comfort but a street driven car, we like to keep as comfortable as possible, at least, most of us do. Although when you replace your engine mounts with a aftermarket set, you will always notice an increase in NVH (noise, vibration and harshness), this is very limited with rubber mounts. Of course they have a higher durometer, but they will increase NVH levels only slightly compared to other materials like polyurethane. Hardrace street engine mounts have a durometer of 50 degrees.

Race engine mounts

Hardrace race engine mounts are initially developed for cars that are driven on the circuit or used for drifting. However, you could also use them in any street driven car. You will hand in a bit of comfort but in return you’ll get better power feedback. As they are stiffer compared to our street engine mounts, you should expect a few vibrations in the dash when idle. Hardrace race engine mounts have a durometer of 70 degrees.
