Stock spring rates?

[sreams]

Hello all,

I am considering Carl Nelson's springs for my CS. Ben got back to me saying the fronts are 225 lb/in and the rears are 250 lb/in. Does anyone know what the spring rates are or the stock springs, for comparison's sake?

Info on springs from myE28 site and knowing that a 72 3.0 weighs in at around 2800 lbs without fuel and an e28 (non M), at about 3000lbs. Obviously ballpark pending options like A/C but gives some insight (or just ask Ben!)

Hmmm... Using online conversion, that comes out to over 2000 lb/in, which obviously wouldn't be right. Any help with the conversion would be appreciated.

Here are some conversion examples:

looks like we're off by a decimal place...
