Spring rates

I need to replace the springs on my De Dion HPC which has wide track front suspension.  All up weight including fuel and me is 615 kilograms and weight distribution is 52% rear/48% front with equally weighted diagonals. 

I'm running Toyo Proxes R888R on 13" wheels.  Mostly road use and some track day.

I know that there are theoretical formulae for calculating spring rates but I would be very interested in practical experience and any information on what contributors find works best for them if anyone is willing to share it.

Many thanks,

Barry
