Bilstein B14 Spring Rates

[JamesAshleyRS197]

Hi All, Can anyone definitively tell me what the spring rates (in lbs/ft) are on the Bilstein B14 kit for the RS197? I've done some research over the weekend and 60NM keeps popping up but that only equates to 44.253 lbs/ft and that doesn't make any sense. I'm looking to do a 2.25" coilover spring conversion on mine but I need to know the original specs so I can purchase the right springs.
Thanks in advance

The imperial measurement is lbs/inch

You are right! My bad!

I think I've worked it out now. It equates to 531lbf/in.
