Square Setup - Opinions Wanted
 

I am looking for some thoughts on my specific options with the following equipment. First, I have two sets of OEM Sport wheels, so I can run square wheels with 4x 19x10s or keep the OEM wheel width stagger. Second, I already have a pair of 275/30/19 tires. Normally, I would have gone with a 35 profile on 275 tires or wider than 275 with a 30 profile but here we are.

So my question to you is how should I finish off this 275 square set up?

Four rear wheels with same profile tires?
OEM wheel stagger with same profile tires?
Four rear wheels with 35 profile in front and 30 profile in rear?
Four rear wheels with 30 profile in front and 35 profile in rear?
OEM wheel stagger with 35 profile in front and 30 profile in rear?
OEM wheel stagger with 30 profile in front and 35 profile in rear?

There is one other option I am considering, which is picking up a set of 305/30/19 for the rears. In that case, should I run the 275/30/19s on 19x9 or 19x10 wheels in front?

Please note that this car is my DD but I have autox or track plans (as financially able) for when it is no longer my DD. Any thoughts you have behind your reasoning are most welcome. I would have made this a poll if I just wanted answers without explanation :tiphat:

I'm running a square 18x10.5 wheel with a 285/35r18 tire. a 30 series tire should be alright with a 19 inch wheel. aside from that check the offset of the wheel for the front. (not sure of the oem offset off the top of my head). What are your suspension mods?

Stock suspension for now.

From all my research, it seems that a number of people have had success running four 275 tires on four rear sport wheels. I've run 285/30/19 in this exact same tire on the rear wheels before, so the 30 profile tires I have should work just fine on the rear sport wheel. I am really wondering what the difference is between running a 30 profile or the stock 35 profile and whether I should run one or the other based on whether I run a 9" or 10" wide rim up front. In a non-racing performance tire with softer sidewalls (i.e. not RE-11s), the lower profile should provide slightly better handling in theory, right? So my initial thoughts are wider wheel > narrower wheel and the lower profile isn't a bad thing (NO STRETCHING!).

I realize the wider rear wheel and its offsets may look a little funky up front - I think some people run spacers in the rear to help balance the look. TBH, I don't care about the look, and I have decided not to run spacers. So if the performance is there, it will look like what it looks like.

Personally, I'd rather make some money off of one of the sets of wheels. They will be worth more selling as a staggered set than selling all four fronts. But if you are going to keep both sets and don't mind storing the 4 front wheels and run the square setup you mentioned, you will get some poke at stock height, I'd expect, on the front. The smallest I'd go on the 10" wide wheel is 255/35, if you want no stretch. I've done this setup before and it works. That should fit ok up front.

Have you tried taking one of your 19x10's with 275's on it and put it on the front? Then you'd know how it will fit.

If it were me, I'd keep it staggered and sell a set of your Rays and use that money for a good set of tires or coilovers/springs.

Selling the extra set has been on my mind for a while. They are in the living room right now so I have extra room in the garage. I like having the extra set because I can bring just the wheels and tires to Discount Tire instead of the whole car. That way I can take the wheels on/off the car myself.

Also, I don't want to lower the car at this time. I already scrape my driveway at stock height. I hope to eventually put coilovers on it when it is no longer my DD.

I have no doubt that 275s on rear sport wheels mounted up front will work. There are a number of people on the forum that have done it successfully. And 255s are too narrow for the 10" rear wheel IMO - I've seen some tires that run narrow have a very slight stretch even in size 265 on the rear sport wheels.

I'M JUST GOING TO 245/45'SX18 IN THE FRONT AND 275/40'SX18 on the year..this is on a base 2011 370Z...hope to have this done in a week or two..

Hello there have u done the square set up
Sport rays 19x10 in all four corners
I juat have the two extra rears and planning to do the same share pics if u do it thanks

I sold my extra set of wheels a few weeks ago to a fellow forum member in need before ever testing this setup.

I had a line on an extra set of rears in Dallas while that was happening, but I never found the time to make the drive to pick them up. I'm not even sure if he still has them.

I personally like the stock wheels 9/10 width with 285 35 all around. Gives me great turn in, lift off oversteer when wanted and tons of grip

Thanks for ur commnets fellows
I'm planning to do 275-35 or 265/35 on the front and on the
Rear i would like to go wider 295/35 or 305-30?

^275/35 & 305/30 on sport wheels works well on my car. I'm also lowered on Swifts.

Would have some pics to share zbrah?
