going square how did you like it?
 

Hello,

I am thinking of going square for handling 18x9.5s.

Did it improve feel on corners or any other things to consider.
pros
tire rotations
lower cost tires (than 19s)
better tire selections

cons
sunken rears w/o spacers

Car is not a daily driver, motorcycle is
so now trying to be safer car when rains, ice and snow

streetable decent track day car as well (work in progress)

Any suggestions on the square setup appreciated.

In rain ice and snow wider isn't better
For all other times, wider is better.

That said, go 18x10

follow up on 18x10
 

Thanks yeah that is true.

But won't a 18x10 hit the wheel wells in the front?
Or is it simple to mod if they do?

I guess because stock is 18x9.5 any buddy running 18x10 with no issues road and road track?

with the right offset you can fit 18x10.5 up front on stock body

enkei pf01
 

The enkei's only go to 9.5

who goes to 10.0 for a racing wheel?

I'm running 18x10 +34 as a square setup right now, I have two sets of wheels in that size/offset. With stock camber settings, the top edge of the front tires stick out a little visually, but on aftermarket coilovers lowered a bit with about -2.5 front camber it looks fine. I'm using some thin 10mm through-hole spacers in the rear (extended studs all around anyways), but honestly it's just for looks and nobody would notice much without the rear spacers. There's no one perfect offset to be able to rotate front and rear without spacers and get perfect show-car alignment to the bodywork, but this is close enough for a track car. The upside of being able to rotate/flip tires around all 4 corners easily is pretty huge.

As for brand, I'm using Forgestar F-14s in Matte Black (hides brake dust better!). They're not the lightest wheel on the planet, but they're light enough and they've held up to abuse well. They're definitely stronger than the super-cheapo wheels out there. At ~$1400/set it's a good deal for trackday wheels. I usually order them through ModBargains and it's a 5-6 week wait as they mfg them to order (since nobody stocks 18x10+34 in them).

i have 18x10.5 Enkei's right now all around

prices on good vs low end
 

Thanks for the info on 18x 10 much appreciated.

But out of my price range by 2x at least.

Do people sell race wheels used? If so where is a good site?
I might be able to go to 2k but don't want to go over that yet.

Entry level race rims? Saw advan, forgesta and a couple others at $1k+ a rim. I'm a beginner trying to get used to a decent setup..

lol and I work for county gov. I just took a 2014 sport put ebc red, Z1 ss lines, 34 row oil cooler, hotchkiss sways, front and rear nismo brace and I am maxed but I see the use for the 18s.
How about this what is in 1.5k range for set of four for a couple track days a year and swap for snow tires? is enkei race good enough?

the feel of 9.5 vs 10s??

Right now my turn in feels like the body in the rear is slipping over the suspension by 2-3 inches on a spirited turn. Like loosing grip in back end but I dont think that is it. very funny greasy feel in rear.

enkei 10.5
 

Any issues with rubbing? turning rub, won't mind extreme parking lot turn limits lower.

How much are you lowered?

Right now I'm 1cm then plus 1/2"

Sounds like stock caster, camber toe might handle 1" which I could shoot for??

Would mod if had to but also want blizzak or other snow to fit.
what is the smallest tire that can fit 10.5? I could and will look up.

Enkei 18x10.5
 

We run Enkei RPF1 18x10.5 square lowered with no rub - we do run spacers tho. Tires are Pirelli 305s. PM me - I can do a set of these new in 18x10.5 shipped for WAY less than 2K.

I too have 18x 10.5 Enkeis. I migt get into some rubbing issues once lowered as Mr Focus has already warned me, but I think it's about 8-10mm problem and can be solved with a simple fender roll if needed. I think my offsets are about 38 mm? Not sure, but I think PF01's are more like 25.

I havent gone with the square setup on my 370z yet, but can say when I ran a square setup on my 350z I loved it. The car was so neutral and great to drive. That said, I cant wait to have a similar feeling with my 370z.

I ran a 18x10.5 square setup, Enkei PF01, +38 front with a 10mm spacer, +15 rear (with perfect fitment, no spacer). I ended up changing the front rim to the PF01 in 18x9.5 +35 which fit perfect. Both my stock rims and Enkeis are 275 square, RS3s on my stock rims and R888 on my Enkeis. Increasing the front tire width helped a TON with understeer that I experienced in my first two autox events I did on the stock RE050's.

Oh and for reference I'm lowered on Eibach springs on these setups.

Maybe some confusion on per-wheel vs per-set here? The Forgestars I'm talking about retail at $1399 for all 4 (as in $350/wheel). And bkleeman above is saying well under $2K for a set of 18x10.5 RFP1's (which I would totally grab if I was in the market for another set of wheels right now!).

or last ditch 9.5 and 10/10.5 work.

ive said it before, my RPF1's in 9.5+45 with 20mm spacer and 10.5+15 are perfect. i just so want 295/315!! just to say i have it haha
