is it enkei or BBS?
stock size is 18x8.5 offset +38.
Perfect flush rims are 18x8.5 off +22. Better if you can find wider rims, such as 18x9.5 off +22 or +25. This setup wont rub if you on stock suspension, but if you are lowered on springs or coil, it will depend on your camber setup.
SSR type C RS or type F will look splendid on evo x =)
