coil overs question
hello,
usually the coil overs have two springs...
does anyone know if there is any difference to have the small spring at the top or the bottom?

I don't know the answer mate, but just had a set fitted by LEDA with the small progressive sring at the bottom. I guess there must be a reason for it

it's a helper or tender (i think) spring. It's very soft and is only there to keep the main spring in place when you jack the car up, or if you're of a more insane bent, to keep the spring in place when you become airborn.
They're so soft that they compress so the coils are touching (i.e. become solid) as soon as the car's weight is on them, so they don't actually spring the car at all.

Tath is dead right.
If the small springs are made of 'flat' spring steel then they are there to keep a small pre-load on the main coil when the strut is fully extended (car jacked up or being driven with air under it.
I think Terry's will be made from round spring steel, and are therefore a significant spring rate to compliment the main coil.

You're right Graham - mine are rated from 250-550 lbs - so combined with the linear springs, give a variable (progressive) spring rate. Although I think they are flat still - but are more coils at the bottom than the top - so act progressively
