Also considering the weight difference is 1.1lbs per rim plus the added weight of the tire, he's still already shaving a lot of weight from the rims/tires compared to the 19's.

But it is always better when you're talking about running the same size tire. We are not talking about skinny tires. We are talking about a 275, period! In that case a lighter 9.5" will be perfect. A 10.5" heavier, more weight on the outside of the wheel will be worse! Period! Can't believe I have to explain this to you.

Going to the 9.5" he does impose the 285 is the MAX the rim can handle though. He also hasn't stated what his goals or future plans for the car are. If he plans on adding more power, the 275 on the rear could easily become a weak link. I brought it up as a "consider your future plans" and upgrade route.

I understand that. He didn't ask us what he needs to run, he told us what he wants to run. And since some of the fastest 370z drivers on this forum run 285 square, I'll go ahead and say again, a 275 square on 9.5" will be perfect! And his future goals can allow him to step up to a 285 if need be. What if he wants to race Doran? He's only allowed 245/275 tires. Now the OP has to sell his wheels since a 245 can't fit onto a 10.5" wheel safely. We can argue this all day but a 275/285 rear is more than enough if you know what you're doing and the cars setup properly. You suggesting one day with more power he'll need even wider tires in the rear just goes against him again and others running faster than you or I, making him un-square.

Why downgrade a portion of your setup to get to neutral or to rotate tires. You should upgrade the part that is lacking, not downgrade the part that has more.

I disagree. Square with proper setup will not be a down grade! Lol 10mm is nothing he'll ever feel, or you. Why do you think so many go square?

But then again, you're the ONLY one who knows what you're talking about and anyone who does anything different is an idiot right?

Lol why would I bother with you? You think heavier is better when we're talking about mounting the same size tire onto a wheel. So others never make mistakes right?! Does PharmDZ have the fastest 370z? Does he know his track times? Has he done 10.5" vs lighter 9.5" wheels to see if his times come down? What a retarded statement to think just because people out there have pulled the trigger on certain things that they must know more than me. I bet whats his face must be smarter than me too buying a $2000 titanium cai vs me making one for $100. Because I know that cai makes 100 more HP than me! He must be smart for doing it! Haha what a joke! There is no arguing this. Unless you run 295 square, going heavier bigger wheels is a waste, period. Then like you said there's a trade off. Whats faster? A 285 on 9.5" weighing XXX vs a 295 on a 10.5" that will 100% weigh more? 10mm is not enough to get you faster when you end up gaining more weight. Those guys I can bet will be faster stepping down a size and losing weight.

I agree. I'm not saying there isn't more than one way to skin a cat. But you boldly said one way was better and you gave a reason why and you're just incorrect.

I don't do bad on AutoX, just they are the limiting factor preventing me from going in as fast as I want. So yes, I would like more tire in the front and plan on getting it shortly.

Well I don't know your car and I don't know you're driving so I can't argue with you on what you need. If you need more than go for it. I do find it strange though tons of other cars with way more power than you though run smaller fronts so each their own.

Agree.
