rim size help
 

I don't have excell on my computer fo whatever reason and I would like to purchase some rims for my 94 RX-7, just wanted to know what the widest rim I would be able to purchase (for front and back) without any real fitment issues. Sorry I'm not trying to be lazy but the excell program wouldn't open up in my comp and I haven't found a really good answer yet. Would 18x8.5 front and 18x10 rear fit fine?

ok so I found out I can do the rims that I want (gramlights 57 maximum) in a 18x9 front and 18x10 rear. I just need the correct offsets for them.. would 37 in front and 44 in the back work? sorry i can't open the wheel guide still
