Coil Springs.

i was thinking maybe they changed design for the cf2? but yours is a cf2 isnt it jeff?

Hey Ben notice you still got them quality safty boots on haha I cut a half a coil off mine & I think it came down about 30mm like an idiot I didnt measure it before I pulled the frontend apart but it has an eaven gap around the tyre now & looks heaps better now to do the rear Cheers Reid

[ben]

actually these saftey boots are not so safe anymore.. there getting pretty thin.. might be time for some more saftey boots:)

Jeff I dont understand your analogy ??!! how can you compare the lateral load of a straight length of coil steel to the compression load of a wound coil its two diferent forces IE: leverage verses compression .so are you saying if i had a coil with only two coils as oposed to ten coils it would be virtually rigid??  I did my aprenticeship in the brake/suspension game and thats not the way i was taught         Cheers Neil

The bottoms on mine are as Ben says. This can be seen by looking underneath the bottom wishbone.
You can see the helical spring seat.
Rouge, you may have non standard springs!

Nope, never changed the springs. I would say I'm probably wrong.

Hey Ben get a bright coloured pair this time there easier to find when you walk out of them By the way Jeff is right the shorter the spring the stiffer it is Ive cut plenty of coil springs & they made the cars ride firmer Thats why in the old days to get the race sedans to handle better they would cut a coile or 2 off not only made them lower but also stiffer My 2bobs worth Cheers Reid

Hi Neil, Years ago I did a basic engineering course which contained a module on springs.
If I remember rightly, we were told that the shape of the spring does not alter its characteristics, in that it's movement per given load will be the same whether it is straight or coiled.

Therefore I question whether the two forces of leverage and compression are really different, as the load on a coil (compression) will produce more movement the further away (along the spring) it is from the fixed point.

What I am saying is that chopping a coil is the same as shortening a straight spring....making it firmer.
The number of coils, or their pitch, has negligible effect, (until binding occurs) as it is the length that is all important, but the thickness  of the spring steel will of course also have a major effect.
Regards, Jeff.


edit.. I found this site that explains cutting springs quite well..
It seems we are both sort of right, and George, below.

Hey guys, would it not be cheaper and safer to buy new ones ? safer in that if you buy what you want, it is approved & covered by a warranty, cheaper $185 in that if it fails your insurance will hold up, and cheaper than a cut one failing and destroying your van.

The $185 is the quote i got from king springs for a replacement spring for a cfs, that is an exact size, and height swap. They also told me i can get a lowered spring, i did not want to lower mine so i dont have any info on those. Hope this helps, or not. lol

x2 cuttting spring went out years ago now days its not worth it

[ben]

was it a fad grandad?
