Spring rate of billies PSS and stock springs?

[Hadden]

Hi,

do someone know the spring rate of the billies PSS kit for 172, and the one of the original stock prings?

Thanks!

Stock springs are 125lb from memory. (tahts for the stock 172 the Cup is different)
I think Blistein are 400lb but thats doesn't mean that that much harder damper play a big part.

Nope the rears will be much higher about 180 I'd think.
