Depends on the model of your coupe. It's been a while since I've owned a civic so bare with me. I think that if you have an EX/SI, they came stock with front sways so you shouldn't need the gsr lca's. Although, I don't think they came stock with rears so you will need gsr/aftermarket lca's to fit the rears. If you have the lower trim models, you will definitely need the lca's, bars, end links, brackets, etc.
