springs & bumpsteer

[golfpin]

help please, have got coil spring off a replica cobra, on the spring is painted 80 - 180 this I think the metricated version of what I know to be inch pounds; the 180 appears to be the overall length of spring but what is the 80 and how do I convert to inch pounds? On the same note this car is built on Jag suspension basics and has serious bumpsteer problems. To me the track rod length is too short causing the wheels to toe out from max droop to full bump by 20 mm plus and the available travel is only about 100 mm wrong shock I think, anybody car to comment.
Thanks golfpin

80 N/mm probably=500 lbf/in roughly
