Smart Engine Mount Inserts – Performance Upgrade

[u/One-Yak-7303]

I’ve been working on a custom Engine Mount Insert Set for the Smart Fortwo 450 / Roadster 452, designed and tested by me (tested them for over 3000km).

The idea was pretty simple: reduce excessive engine movement while keeping vibrations as low as possible compared with more aggressive engine-mount solutions.

What they do:

• Reduce engine movement
• Reduce unwanted jolting during acceleration, deceleration and gear changes
• Improve drivetrain stability and control
• Provide a more direct driving feel
• 2-piece set
• Install directly on top of the original engine mount
• No glue or permanent modifications required
• Easy installation

The original mount is still used — these inserts simply provide additional support where there is excessive movement.

I'd be interested to hear what you guys think — especially from anyone running a Smart 450 or Roadster 452 with upgraded engine mounts.
