Basically I'm thinking of purchasing coil over springs and was wondering if they would fit on to the orginal suspension?? cos I'm really not sure :/

 

yes, just pull the strut apart buy taking the bolt off the top, be careful though they will fly apart when the bolt comes off its not that bad though. i shortend my strut to the top of the coilover at its lowest, just cut it an rethread the top. if u dont want to cut it just put it together, but they will wreck ur struts if there to low.
