help with rims size and suspension
 

hey I own a 2003 civic (coupe) stock ,just got it 3 or 4 weeks ago. Am working on it now and I was thinking about putting some rims on it Rota Grid 17x9.5 or 17x 7.5 really don't know on wich one to decide. I was wondering if you guys think my car will need a suspension or any other type of upgrades so the rims feel smother and don't damage my car


thanks!:screwy:
