I have a 08 G37 coupe with Double 5 spoke rims. I have the opportunity to get a set of 12 G37X sedan 10spoke rims. First, are the 10spoke rims a 18x8 or 18x8.5 or 18x7.5? The pic has 10x8J engraved. I believe is 18x8 which are the same as my original rims. Wondering if any one else tried this on their coupe? Want to keep it 18's and squared for cheaper tire price and easy tire rotation. Also the 10 spoke has 2012 tpms and I read it will not work with my 08. Just need to confirm. I photoshopped the how it would look. Any advice is appreciated. Thanks.
