so youve now got the longer ones on the front? :huh:
Guardian.:
IM SURE ITS Normally shorter stiffer springs on the FRONT, and longer softer springs on the REAR, not 100% but nearly. and seats has jack all to do with it.

There are 3 equally important measurements that determenting the compressed height (ride height). They are free length, the rate (how stiff it is) and the load on the spring.
A short but stiff spring can give the same or evan a higher ride hight than a long soft spring for the same load.
Give the lengths you mention, my guess is that they are blue, made?/distrobuted by Bearmach and are BA2102 and BA2104

See page 12 for their full specification
One question, are the coils equally spaced on you lift springs? If so then the rate should be constant, if they are not and some coils are closer together than others then the springs are most likely variable rate, which makes it more difficult to make accurate predictions of ride height.
If you can, with the springs still on your discovery measure the compressed length of all 4 springs, from this it should be possible to work out the sprung weigth on each spring and determine what rate and length of spring is needed give the desired ride height.

I should think you have them on the right way round*, its just the rear springss you have selected are too long and stiff compare to the front springs to give a balanced ride height. Easiest solution is to do like a friend and just put a large oil cooled welder in the back, which will weight it down nicely.

:shock: i must bow down to your superior knowledge of springs not only did you get the colour right you got the make and part numbers right aswell you are the spring king [-o<
well as you got all the above right im guessing you now know the coils are equally spaced i will have a measure up tomorrow i will measure compressed springs and hight from floor to arch and post a couple of pics up so you can all see what im on about cheers or the info
