Spring Weights

[Spetz]

Hi guys,

Does anyone know which springs are the softest, from the lowering range?
And does anyone know the actual spring rates?
I have Tein SS coilovers with 5kg front and 4kg rear springs and wondering how King springs, Lovells etc compare

T1R, they're softer than that. Spring rates are 2.91kg and 3.65kg.

For comparison, the stock CJ Ralliart has spring rates of 3.21kg/mm front, and 2.6kg/mm rear. So, those are lowered, but quite close to OEM..

BUT

That also means you have more opportunity to dive and touch-down.. slightly stiffer springs can save scrapes...
