from the loks of the prices those are the full system so they would include the shocks/struts. you would be able to adjust them and get your setting so you can make hard turns seem really easy.
As for which to go with I would suggest the tein set up but that's just my $.02 They are very reputible and have tested and track tested there products time and time again....also you can find a few articles on them in SCC and SS. Good luck on your choice..
