Sigma front spring rates

[Connrod]

Does anyone know what the standard front spring rate is for a sigma engined car, it has the super sport suspension fitted at the moment as it was a race car, I am converting for mainly road use, its fitted with 250lb springs at the moment which may be ok for the track but i want some a little softer for the road.

Can't answer the specific question re Sigmas but I run 250 springs on the front of my VX, lowering the rate can introduce real issues with the front suspension bottoming out on dips, so be careful.

I think the standard is 170.
