Spring Rates for Nitrons

[MrChips]

Evening all!
I'm going to be ordering a set of Nitron NTR1's soon and just wanted some opinions on spring rates. It appears that Nitron supply them with 400lb front and 325lb rear, but the TVR Power ones that have Eibach springs use 350lb rears?

Anyone used any other spring rates, or felt the need to change from the "standard" setup?

They'll be going on a Tuscan 2S, which will solely be road use, and I'd prefer supple rather than firm in terms of setup as I don't want it to feel jarring etc.

Cheers

After a lot of experimenting I found that 400 lbs at the rear and 325 or 350 front works best on the Tuscan because of the big ass.
This gives an optimum balance.
Furthermore, don't set the Nitrons too hard, about 10 rear and 13 front (from full soft).

this is for a 2S.
