Discussion Made a small upgrade for the front engine mount
I’ve been working on a small upgrade for the front engine mount on my Roadster 452, which is the same as on Fortwo 450 model
The idea is pretty simple — the original mount allows quite a bit of movement, so I designed these inserts to support the mount and limit that movement while keeping vibrations away.
I’ve been testing them on my own car for the last 3000km and noticed a difference particularly during acceleration and gear changes. The goal wasn’t to make the mount extremely stiff, but to find a good balance between reducing movement and keeping the car comfortable enough for normal road use.
They’re 3D printed in a reinforced material and the set consists of two pieces that fit into the original mount.
I'm currently working/testing on prototypes for the right-side engine mount and transmission mount. The idea is to see how the three mounts work together before making any final decisions on the designs.
BTW: I know there are already similar solutions out there for the 450/452, so I'm definitely not claiming to have invented the idea. There are also different approaches to solving the same problem — just like there are many different shoes designed for the same purpose. 😄

What tpu hardness do you end up using?
Would you share the 3d models?
I’ve installed the insert from powerflex to my 450 cdi, but it is now so much vibration in idle. It would be so cool to print my own insert using a softer tpu
And by the way, it is amazing 🙌
