i have a dyane and one of my rods snaped Sad

so i took it to a friend of my dads and he welded on a headless bolt. I wanted to drop it so all i did was unscrew it.

also a quick question do any of your lowered cars have any trouble through an mot, it isn't scraping height so would it be ok?

last page or so seems to have added confusion to the subject.

raising and lowering has little effect on the load on the spring, the car still has the same mass the spring has the same amount of give, There is a change in load due to the geometry of the cranked nature of the arms and the tie rod locations. This makes it feel as if the spring is softer.

If you lower your car on standard springs by lengthening the tie rod then there will still be the same amount of travel in the spring and you may well end up riding on the bump stops or bottoming out

lowering by fitting shorter springs has the advantage that a shorter spring is stiffer so there is more chance the spring can do its work without the suspension bottoming out. There is also less chance of having too little thread in the tie rod end.

Springs are just steel rods rolled up so they take up less space.
If you put one end of a steel rod in the vice and hang a weight on the free end then generally :-
a long rod will move more
a short rod less
a thicker rod also less
a short thick rod the least

a good spring manufacturer will be able to work out what you need taking in to consideration the diameter of the spring the amount of turns , free length and wire diameter.

shorter stiffer springs are available in the UK originally for the race cars.

Hi guys, I might have found a company here that could produce springs for the lowered 2cv...does any of you have the dimensions of the 179 ECAS springs, are they coiled in the same direction as the "normal" ones, how many bends/coils are there, is the material thicker than standard?

this company deals with all sorts of springs for tractors and agricultural machinery, their specialty is making springs and safety pins of all sizes

Any info will help, tnx;)
