those are the spring rates front and back. 
the ride high/adjustment is not mentioned but a tthe top of the page it says that it is as much as -120mm on some models. so it will depend per car etc.
However, i would fairly confidently say that it will be at least -60mm mybe even 80/90 etc all the way up to 120 but 60mm is plenty anyway.
You best bet is to follow the link, find a phone number and ring them up, they will be able to answer all your questions
