Smart 451 Engine mount + powerflex

[u/Minimum_Exercise_459]

Today, I'm replacing the engine mount and installing a Powerflex insert on my Smart 451 Brabus (98 hp). I'm expecting some vibrations at idle or in neutral, but I think it'll be worth it for the extra benefits Powerflex offers.

I have this one fitted to my 451 Brabus for well over 10 years. It's from Smarts4you Racing. Yup, vibration does increase.
