Suspension

just a curious question about strut/shock and lower springs.
everything i look up says it excludes the hicas… could someone explain this to me? should i jus ignore…ex. im looking into kyb’s (gr2 or agx) and some eibach springs. should i jus buy the needed parts for a 91 240sx???

anything would help.

question has been answered , can delete post

i’m still cerious… i think hicas is adjustable but why would that realy matter.
