Nothing is ALWAYS better, I can't believe I have to explain THAT to you. Putting a 285 on the 9.5" rim works but it is not always optimal. If he was running an R-comp tire with very stiff sidewalls, then yes stuffing the widest tire that fits on the rim would be ideal. Putting that same 285 on a 10.5" rim with a street tire with a softer sidewall would yield drastically different results. So the answer is IT DEPENDS!

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.

Just simply amazing. You do understand that people going faster or slower on a particular setup is due to more than just the tires. It's the total package, not just one single item. As for comparing it to a RC in a full race series? I highly doubt the OP is going that far. At that point, having to buy one more set of rims/tires is NOT a big deal. At that point, he'd have SEVERAL sets of rims/tires. Being square is not an automatic win or lose.

People go square for a variety of reasons. #1- Bring the car closer to neutral and #2- Add in longevity from being able to rotate the tires. It does NOT mean OMGWTF you have a square setup, you will now decimate all.
This ignores several things. Square is not necessarily the IDEAL setup for every track. Due to weight differences, and different tracks, the tires may heat up differently and adding width can help offset this. Different drivers and different courses also require slightly different setups. Some drivers prefer a bit of understeer, some want neutral, and some want slight oversteer.
So yes, reducing traction even by 10mm just to get square still reduced overall traction on the vehicle. If you wanted to change the balance to get more neutral, you can get there by adding more traction to the front instead of removing traction from the rear.

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 didn't bring up PharmDZ as a he is right and 10.5 is the best. I brought that up as proof of your failure at READING COMPREHENSION... a point which you made for me AGAIN.
And as much as you argue that 10mm doesn't matter... do you think 1lb is going to be that huge of a difference? Your same argument can be used against you. Have you gone and tested every wheel/tire combination back to back and are you a good enough race car driver that you can without a doubt say that any change was due simply to the change in tires? I didn't think so.

And please, where did I ever say that one way was better? I simply asked why not go with this. You are the one RIGHT now saying that I am incorrect. I to this point am STILL saying IT DEPENDS on a bunch of factors that the OP has NOT answered yet.

Agree.

Lol...so you don't know my car or what power I make? but you're sure that other cars with way more power run smaller fronts? That about sums up you and your argument.
"I don't X, but that won't stop me from arguing Y." If you READ, something that you clearly suck at. I mentioned Auto-X, which pretty much is get as much tire as you can. But I'd love for you to show up with your cheap plasti-dipped rims and $100 dollar exhaust and "go faster" than me on an AutoX.
Here's another tid-bit for you. Simply adding wider rims/tires may NOT make you faster if you do not upgrade the rest of the suspension and get an alignment to take advantage of the extra traction. As I've been trying to tell you over and OVER, there are a LOT more factors than simply saying a 9.5 is lighter than a 10.5 so it will ALWAYS be faster and staggered is bad.
Once again, great job on failing at reading comprehension. Maybe if you paid more attention at school you'd be able to afford to powder coat a whole set of rims or buy a real exhaust.
