I'm building coilover struts for my 1200 ute. It has L20b installed so is heavier than a series.
Can someone with this setup help with which spring rate they are using and how it drives(harsh or soft)
Shocks are 300zx and its for daily driving and spirited cornering

Stock springs (with a series) are around 90lb/in (if memory serves me correct)
I've heard 250lb/in rides harsh.
So I'm thinking 175-200lb/in is a good comprimise. Would love to hear from fellow owners before I take the plunge.
I should add that I'm running 165/55/R14 tyres (which might add to the harsh ride of a higher spring rate)
Also tender or helper springs: Needed/recommended or not?
