I'm sure Nissan engineers tried a tire size or two and played with the stagger front to rear before settling on a 30mm offset F/R. I find the balance to be pretty neutral on the track, with maybe a hint towards oversteer with 275/305 and my suspension settings the way they are.

If you want the back end to come around even more easily though, I can see why you'd want that. I think a couple of members here have tried a totally square option just to have the flexibility of rotating all the tires as well. Totally agree the larger rears aren't needed from a traction perspective with NA builds though, RE-11's or the like in stock sizes would give you more than enough grip.

I hope that setup works well, feedback when you get it all installed and on the track

Well the use of need I guess was more personal. From my experience thus far with the car and stock suspension (with exception to Swift Springs) it has a tendency to understeer and plow through very tight turns therefore more grip was needed up front. I feel I have to fight it in order for it to bite more in a tight course like AutoCross. I also take it as a clue when some of the more popular racers on the board seem to like a more square setup.

So in an effort to see what I think works best I am increasing my contact patch up front. In stock form the car appears to have a tendency to understeer not oversteer which is why I said it needs a square setup but then again changing suspension may cure this issue as well as I feel the car needs a lot of negative camber up front. Who knows perhaps all it needs is negative camber and not the huge tire I am putting on now but I dont have camber arms yet so I am trying this first.
