Congrats! Welcome to the headache of being an fc owner haha. That thing looks like its in pretty good shape tho. If I were u I would stick with some coils and dtss eliminators and call it a day. Maybe some rear camber adjusters too. And if its a s5 that means u probably have the viscous lsd. Try to find an s4 lsd and u will b a happy camper. Rx7club.com is a great fourm also, plenty of knowledge and info over there. Hit me up if u ever join, Slidinsilly. Im usually only in the drifting section tho.
