Title: Rear engine mount spring
Post by: Italdesign on March 16, 2009, 06:15:20 AM

This may seem a silly question but why is the engine mounting sooo soft on the Fiat 500/126?  I have fitted a Panda 30 head with a Dellorto DHLA 40 to my Niki. I am in the process of modifying my mount to better support the carburettor but I also wondered if a stiffer rear engine mount or some sort of stabilzing bar(for the motor) might help it run a little better.
 
Can anyone shed any light on this?   What would be the pros and cons of such modifications, and if this is advisable where might I be able to source the parts?

Regards
Stephen

i have used a cut down dirt bike spring in the past which was very much stiffer , and you can fit a stabilizing bar easily if you wish to stop the engine rocking i think you can buy the stabilisers in italy but its easier to rig up something yourself it wont be too hard.

Thanks for the suggestions.

I've since found out that Middle Barton Garage have a heavy duty spring for modified engines (cost 12.50 pounds).

it'd be interesting to see which is nicer over bumps.. mine feels much the same as normal until you hit a bump, harder springs would probably cause more general vibration..
