going square how did you like it?

wstar

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).

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.

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.

bkleeman

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.

spacers???? my 18x10.5 +15 rpf1 is perfect in the back. what spacer do you need back there? also 18x10.5 +15 for the front is crazy offset anyways. am i missing something or do you have a different wheel? i only see 1 18x10.5 from enkie.

if i did a 10.5+15 on the front (again i only see 1 rpf1 in 18x10.5) where im flush now, itd be like putting a 23mm spacer on.

Same wheel front and back. We're only using spacers on one end, but I dont recall which - I'm 600 miles away from the car at the moment so I can't go look. Our rules allow for a 10.5 wheel up front and an 11 in the rear but Enkei doesn't make an 11 and that's the only offset for a 10.5 so that's what we went with. We go through a LOT of wheels so I wasn't going to switch over to a more expensive wheel just to get an 11.

The Pirellis we use have a rather tall sidewall and we can adjust ride height so we have a lot that we can play with regarding fit.

Wow. Well if you're 100% ill take your word. But that wheels like a 51mm spacer on the oem. I'm 23mm smaller and 1.2" lower with -1.5 camber and poke 1/8". Maybe you run -4 camber?

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.

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!).

i wanted to sell mine for a more sqaure but having second thoughts. like wstar said there is no perfect setup so i can sell these and get new RPF1's in the same wheel but all i end up doing is buying different spacers and moving them to the rear and i lose front end weight and move it to the rear so...

my wheels were like $1300 and for a RPF1 how you can beat that??!! you can get them here and there for $1000-1200 easy.
