Oh great, another motor mount option - just what we needed... *Insert sarcasm here*
We know what you're thinking, but you're right. This is exactly what the community needs.
Over the years, we have heard the same gripes about motor mounts over and over again from owners in each community: "My car rattles so bad ever since I installed my motor mount." Yet it seems like most manufacturers have the same response:
We've heard your voices and developed a proper solution.
EPDM Bushings
Our motor mounts will utilize two press-fit EPDM bushings, unlike most other aftermarket mounts on the market. EPDM is the perfect bushing material because of its high resistance to outside atmospheric elements (heat, ozone, weather), chemicals, solvents, abrasives, tearing and vibration. Because EPDM has a higher density than urethane, this means we are able to use a softer/lower durometer bushing to keep engine vibration to a minimum, all while improving rigidity in comparison to the factory mount(s). Unlike urethane bushing inserts, EPDM bushings will not mushroom, wallow out or breakdown over time with use. There's a reason this type of bushing is used by OE manufacturers.
In an effort to streamline logistics and purchasing for both the end-consumer and Dealers, we will only be offering one mount option with one standard "stiffness" for each application. Currently, our team is testing a variety of bushing durometers at both sides of the mount, from 55A to 80A. We will collect real-world data from numerous different vehicles and drivers to find a one-size-fits-all combination of bushings that suits most anyone.
All bushings will be press-fit into our precision-machined billet 6061 aluminum motor mount assembly. This press-fit connection eliminates any possible gap to ensure that there are no metallic vibrations or noises, allowing the EPDM to absorb any engine or chassis vibration. Bushing shells and center inserts are Zinc-coated to aid in corrosion resistance.
Rear Motor Mount: I-Beam Design
The first two projects we've decided to tackle were the rear motor mounts for the 2016-2021 Honda Civic 1.5L Turbo / 2017-2021 Honda Civic Type-R FK8 (shared) and 2022+ Honda Civic 1.5L Turbo. Just looking at the factory rear mounts and putting together some first article design concepts, it's easy to see the similarities of an engine's connecting rod. Immediately, we ran off with an I-beam style connecting rod-esque design cue. I-beams work excellent for mounts and connecting rods because of their resistance to bending, stress, vibration and reflection. We were able to add a significant amount of material to increase rigidity and strength over the factory.
Stay Tuned!
After our testing is finished and production has started for our first two mounts, we will be working to develop more motor mounts for relevant platforms. Stay tuned for final pricing, data and expected release date.
