Finding Balance between solid mounts and NVH
I first ran the Torque Solution front motor mount w/ the default/stock mounts it came with and the cabin vibration was bad (but expected). I felt like there was some room for middle ground.
VampyreX13 to the rescue!
- I discovered the 3D Printed slotted bushing by VampyreX13 on YouTube.
- VampyreX13 shares the 3D files for download on his Thingaverse page.
- It turns out the TC2 and TC1 use the same bushing, so this mod is shown below on the TC1 Torque Solution motor mount.
Huge shout out to VampyreX13 for making this possible!
Noise, Vibration, and Harshness (NVH)
Is a common side effect of running stiffer motor mounts.
When you upgrade from soft OEM rubber mounts to polyurethane or solid mounts, the engine’s movement is reduced—but so is its isolation from the chassis. As a result, more engine vibration and sound are transferred directly into the cabin. It can become most annoying at a stop with AC on.
OEM mounts are designed to absorb vibrations for comfort. Stiffer mounts prioritize performance by limiting engine movement, which improves throttle response and shifting—but at the cost of comfort.
3D Printed solution

- Be sure to print with 100% infill (Solid)
- I’m using 95A TCPU red in my example.
