Hey guys, can anyone offer incite to the benefits or draw backs of using a square setup, e.g 9.5J all round as opposed to 8.5 up front then 9.5 in the rear. I'm more inclined to stick with staggered as this is what the Nismo guys recommend?

Cheers!

 

9.5 all around is one thing, and i would run it if they didn't make a 10.5 rear. Now for the square thing. With a 9.5 f and r combo , you can run 275/35 front and 275/40 rear getting a nice setup that gets rid of most of the understeer.

Personally i would never run anything smaller than a 9 up front.

 

running a square fitment front and rear typically nets a balanced and neutral feeling for the car throughout turns and quick transitions. Depending on your sway bar set up, it will give an equal amount of understeer and oversteer or at least very close to equal.

The Z/G is a little nose heavy and it benefits from a nice wide front tire to aid in turning and braking grip. Assuming you put the exact same size wheel and tire on the front and rear it will also allow you to do tire rotations to maximize tire life which for some is a concern...i personally think its an awesome look as well.

Going staggered does a couple of things. First it dials in some extra oversteer, but you can always dial that out with sway bar and alignment settings. it also gives what I detail as a snappier turn in due to a smaller contact patch that the car has to fight versus the rear.

I agree with terrasmak, a 245 is a little small up front, but it is very street friendly. A thinner front tire will be easier to drive on the streets because its less prone to groove tracing.

For large fitment, I think a 18x9.5 and 18x10 front to rear is a good staggered size. 18x9.5 or 18x10 all around works really well for square fitments with a 275 tire.

good luck, commiting to wheels is tough.

 

How does putting a wider tire on the rear dial IN some oversteer? Defies physics unless the alignment or springs/sways are adjusted. Then it's not necessarily because of the tires since there multiple changes made at once.

 

Been discussed a dozen times. Been done a dozen times. But thanks for asking.

 

You mean understeer, I hope. I should know, I run an 11" rear.

 

what do you guys think about putting 10.5 19's all the way around? Would they fit good or would it involve body work and a big headache?

 

It's been done. All depends on the offset, tire size, and camber you use. Personally I think it's pushing the limits more than necessary. A 275 tire is usually recommended for a 9.5" wide wheel and if a 275 is good enough for the front of a C6 Z06, it's good enough for me.

 

So much false info in this topic its disgusting. Idrive_MD gave u a nice basic gist of it, you can research more to your liking. Dont listen to the ones commenting on his post they have NO IDEA what their talking about...

 

reason I ask because A guy is selling 19's on here that are 10.5. I just dont want them poking past the fenders like paco and his crew.

 

Are you sure ???

 

if it was me choosing wheel and tire combos i would look at my F/R weight distribution and equal the F/R tire width to it. So you left with finding were you body sits in the car's weight balance and how you are going to balance the lack of rear weight in the Z or the excess of front weight.

9.5 with 275's look more square on the rim and protect the rim more.

 

you should do some reading on wheel fitment..

 

Excuse me, I had a quick question and have been searching for a specific answer but couldn't find exactly what I'm looking for...

What is the largest size tire you can put on both the front and back of an 08 350Z to create a non-staggered set-up and not modify a single thing on the car like having to roll fenders, camber & toe adjustments, spacers, etc....?

Part 2: What wheel size and offset range would I want to get to achieve this? Thanks!

 

I guarantee you that 18x9 +30mm offset with 275's fits easily.

The widest I've seen fit that I would put on my own car is 18x10.5 +15 with 285/30/18.

What "fits" is relative to who you ask though. MANY wheel/tire combos I see on here I would personally say don't fit.

 

i'm running 18x10 +19 offset (5mm spacers so actual offset is +14), 265/35 all-around. steering feels more neutral than a staggered set-up imo.

Without getting all technical, I much rather a square setup over a staggered. Square being same wheels sizes and tire sizes.
