You would be well advised to find out exactly what you are getting here, as there is very little info in the advert.
Usually you get what you pay for and these are definately on the cheap side.
The advert states that the brand is KW which they are certainly not, unless I am missing something.
Also it does not state if they are true coilovers or not.
Might be worth a punt, however that will depend on your expectations.
