Stock offset on 05 civic lx????
 

Okay, so I've decided on some 18" wheels, and have been doing a LOT of research, but I can't find what the stock offset for an 05 civic lx is. I think it's 40, but not sure. The wheels I want to get are Enkei RS-6's, and the offset for those is 38. I think this will mean my wheels will be closer to the body and farther from the body. Do I need spacers? Any help would be much appreciated.
