I've run a search and came up with bupkis several times, so here goes:

Anybody know the spring rates for the STOCK OZ springs?

What about the rates for the Progress springs. Yes, I know they're a progressive rate spring, but that doesn't mean they don't have rates. It just means that the rate varies depending on the compression of the spring, so we'll have a range.



According to the Evo forums, the Evo stockers are 180 Front and 225 Rear (this is the kind of info I'm looking for)

Thanks all

 

I don't know off hand, but my butt tells me that they are probably around 150-200. That's comparing them to the 280/392 rates on the Tein SS kit.

 

Cool, and the s-tech lowering springs are 130F/230R..... so the stockers are even softer than your guesstimate. s-tech's lower 1.77F/1.06R

we should get lots more info and sticky this for comparison purposes. Here's Teins site for us "Regular" lancers: http://tein.com/ti/r66.html
