The more I read the more confusing it becomes. I currently own a 2008 350Z Enthusiast model with stock tire and wheel sizes. Wheel F 18x8 R 18x8.5, Tires F 225/45-18 R 245/45-18. I want to put Bridgestone Potenza RE760 Sport all around. First setup is F 245/45-18, R 275/40-18, Second setup would be F 245/40-18, R 245/45-18. I don't track but drive aggressive. Thanks for the help.

Second setup is fine. Square setup (width-wise) will provide more neutral response and helps curb understeer.

Personally I wouldn't put 275 on an 8.5" wheel or 245 on 8". In your case, I'd run the stock size combination unless a pair of rear wheels used upfront, then I'd run the 245/40 & 245/45 combination.
