Spring (Coil) load or rate for roaduse.
Discussion
the coils / springs fitted to my Ginetta G4/S4 are too hard for road-use. (i pressume it was setup originally for tracks).
anybody can tell me a spring-rate which would be ok for road use?
ford banjo live axle, 4 link, spax-dampers (non-height adjustable).
front-suspension same...too hard.
which springs can i use there? my front are the spitfire-type.

You need to know what the current springs are. If you can remove them, they might still be marked, or some motorsport places have gauges to measure spring rates. Then try dropping them by 10 or 20 lbs and see how its feels. I ended up dropping the spring rates from 325lb to 275lb on my G33 (fronts) before I was happy but I now have a workshop full of new unused springs. One level of springing may not suit everyone, so its really up to you.

unfortunately there is nothing imprinted or stamped onto my springs, nor are they the original ones.
and i do not have any companies around where springs can be "measured" on their load.
found an overview of technical datas from another ginetta owner in the history of my car. he fitted 150lbs on rear, 250 on front.
for the rear i can get differnt rates very easy, but front ones are spitfire shocks and i gues i cant use spitfire springs?

As a starting point contact Duncan Campbell at the Ginetta owners club. He has a similar car and also worked at the factory when it moved to the north of England and may well have access to the information you need.
Failing that, if you can get access to a corner weight gauge and have the existing weights checked at the front. Then measure the thickness of the wire used to make the spring and also try and get its free length dimension, you may need to remove a spring to do this. Then you may then be able to talk with one of the spring suppliers about the measurements you have and what you are trying to achieve and they may be able to make suggestions.
If you are not in the UK then you might try speaking with AVO shockabsorbers in Northampton in the UK through their website. They are very helpful.
