Busted up my 57 offset rim OK to get a 56 offset?

Well the story goes i have FR c5 z06 rims 18x9.5. the wheel offset is 57. I need to order a new rim because i cracked mine when i jumped a curb. The 57 offset is backordered about 1 month but i can get the 56 offset in 2 days. Should i wait or get my car up and running with the 56 offset? any quick help would be great.

thanks guys

sure....unless you think that 1/32" difference will make your tires rub
