I think I post this yesterday but I can't find It, anyway I am about to order a new spring for my engine aft mount, there are two types of springs, standard and reinforced, thinking about reinforced have you try It?

General Engine mount spring
Thomas, I have fitted the stiffer uprated spring to my car, it does help control the engine movement

Ian.
Update, just put the stiffer spring (not those red colour super sport versions but just a harder one) anyway start the engine and little car almost cut in half!! I mean now at idle is like there is no mount there and engine is bolted directly to the chassis. I think this Is a very bad idea except something is wrong here. Probably I will return to original spring.

Just saw your post, I would recommend the standard spring. I've read a lot that the reinforced is too stiff, and as you've shown, it's pretty tough on the poor 500
There is some sort of reinforcement plate that goes under the gearbox (I think?) and it's from the 126. It's almost like a torsion plate, and its said to help.

This is the new "original" spring I bought; too stiff because it has too many turns in the coil.
MAL_3609 by Peter Thompson, on FlickrI plan to replace it some time with the genuine original. But I then bought the 126 plate because the problem was the extra torque of the 126 engine. But now I think like you Thomas, to avoid the knocking the spring just needs to be softer.
I've tried a few things with engine mounts after having problems with a non-standard exhaust hitting the bodywork on my Giardiniera.
There's a spacer on the bolt that compresses the spring, Gordinir8's post sounds almost as though he might have forgotten it on reassembly, going from too soft to solid.
All things equal, the more coils there are, the softer the spring, because each coil needs to deflect less for the same movement.
The rubber bushes on the front "bridge" support of the gearbox can become rotten from oil contamination, or their tightening nut loose, the 'box will then sag and hit the bridge support.
I think the engineers at Fiat picked the right spring for the purpose of an original engine, any problems must lie elsewhere.
Just my 2 cents, one-car "expert" advice...

With the old original baybe tired spring if I push the engine with hand she goes all the way down to the bump stop, (Mount has a rubber stop inside) Now if I press the engine actually I am compressing the rear suspension!! It is that hard. Problem with my mount was the four rubber bushings which where worn and I replaced them togeather with the spring which I will discard. I think this one is only for racing use
Something about your description seems a little "off" to me...
If I push down on my engine, the car suspension goes down of course, but the engine mount spring also compresses, but not down to the stops.
The mount only has two rubber stops (doughnuts), not four.
I'm just wondering if a previous owner maybe lost the spacer tube that goes on the center bolt and piled extra rubber bushes instead (?).
Unless there are differently-arranged mounts I'm not aware of...

I think that's what giordini must have whilst gordinir has the original type.

My new spring arrived yesterday. I bought the 126 one because it looked stiffer but it was sent before I had chance to question them about it. Does anyone know if the 126 spring is the same as the 500?
FD Ricambi lists the same spring for both cars, but I have reason not to trust them 100%.
Where did you order El c. ?
I've now checked another supplier: different springs for the 500 and the 500R/126 (500R/126: fewer coils = stiffer)

I also used the original spring as the new uprated one was too stiff and caused everything in the car to vibrate. I wasn't too keen on it.
But the wife refused to get in the car.
So maybe I will put it back in

My engine goes down to the stops but ok not very easy. It also had side play due to very worn rubber bushings. Now the mount has four rubber bushings and a rubber stop. The spacer is also there. Here is a picture from Axel gerstl site (without his permission, i hope it is ok) from a mount rebuild kit, there are four rubber bushings.
Anyway i just put back the original spring and together with the new four bushings things are much much better than before, ofcourse a little stiffer spring could make things even better but hey it's an old little car.
