Hi Ben’

That’s unusual!
I can only guess at a couple of possibilities. The Jag spring kit I
purchased came with a selection of plastic spring packers. You’re
supposed to fit the requisite number / thicknesses according to the
colour code painted on the springs. If I had fitted all the packers
supplied, my car would have been too high at the back. As it is, the
back is about three-eighths of an inch higher than the front, unladen,
measured from the floor to the underside of the wheel arch at the
centreline of the wheel. Looks just right.

Alternative suggestion. Did the car originally have the “Sports-Pack”
SLS fitted which has lowered suspension? If so, and the Non-SLS
springs [and dampers(?)] fitted were of the “Non-Sports-Pack” variety,
I guess the back end would be too high in relation to the
“Sports-Pack” front end.

DO NOT go back to fitting the shorter SLS springs!

rear of the

car
sat too high with the springs that were provided.

Wrong springs obviously :wink: I believe that there are a number of
different types of springs for '40’s dependent upon many
factors.

the car was actually there
to
have the springs removed and the original sls springs
reinstalled to see if
the
car would level out.

Not a chance! the original springs are designed weak as part of
the weight of the car is always taken by the hydraulic struts.

My suggestion is to contact a franchised dealer, give him the
chassis number of the car and make sure he cross-references this
to the spring part number.

I think that this is the most important point as you will only
know whether you’ve got the correct springs on after the job has
been completed otherwise! How you get the work done is up to
you.
