Spring rates for Nitrons ....
Discussion
On the S I was running 400 fronts and 350 rears ... The springs were fine and the ride would have been much better if the dampers had been up to it ...
My understanding was that as standard (and confirmed below) was 280lb rear and 300 lbs front.
I have a friend who ran 700lbs front and 500lbs rear on his S very successfully in the sprinting field. You know him Pete !
The ride on the car for normal road use was very good. But too harsh for the Griffith.
A 12.5% increase would give only 315lbs and 360lbs.
My experience has been that the better the quality of the damping the harder the spring rate can be without detriment to the ride quality.
Digga, your spring rates sound about right to me ..
Guillotine, are you sure that your spring rates are harder at the rear and softer at the front ???
My basic school boy maths says that the standard rears are 87.5% of the fronts and therefore to enhance them in line with the orginal would lead to a 350lbs rear and 400lbs front.
325lbs rear is too soft with according to the maths, but that does in no way take account of dampers, car set up and driver preference.
This also doesn't take account of it being a rising rate soring either and this is what leads to the initial 'barge' like action of my beloved Griffith on track ...

Johno,
in a garage awaiting 'some' work.

Indeed .... still there, but there is progress .... that progress will result in the necessity for the new dampers
... The old are knackered anyway and were due a change, but I might aswell do the whole lot at once. Should see it back in time for Touring in Scotland at the end of July/August !!
Drop me a mail and I will expand.
