Default Jag IRS rear spring rates

Anyone care to share their spring rates for their jag IRS. And wheel size (15, 17 or 18).

I am reading plenty and the variety of info, some of which I find perplexing.

I know that there are many variables such as corner weights, spring angle, wheel size,engine weight and output, driver/passenger weight, however just seeking some rates that others may be running.

Reading through past posts, it seems that between 300 -350 was suggested. However i have come across recomendations from 200 up to 400, then other readings in that a 350 spring rate, with two shocks on each side means that this is an effective rate of 700. Is this right? It does not seem to be a good balance when there may be a say 350 on the front.

Feel free to school me on this as the Jag IRS is used in many varied builds, cobra and non cobra and I have over read in distiguishing fact and fiction.

Cheers.
