255 Square possible?

Taskmaster · 10-25-2018, 11:04 AM

Is it possible to fit 255 Square on these cars? If I HAVE to, I would run a spacer, but I would prefer something like I had on my E92 (17X9 ARC 8 ET30)

It's possible, but likely won't be a bolt on fitment. Some degree of fender modification and camber plates will be needed.

I don't mind that -
18" wheels and I need an offset that can be rotated and accommodate a 255 tire.

Found this for anyone else who wants to look:

Because the 2-Series fitment requirements are so specific, we have listed only four different wheel sizes which can be used for nearly all types of street, track or race driving. They work well with anything from all-season tires to all-out racing slicks.

Square Setups
Recommended for most types of street and performance driving. Allows proper front-to-rear tire rotation to extend tire life & improve handling balance.

Front & Rear: 18x8.5" ET35 or ET38 with 225/40-18 tires
Popular fitment.
Typically a direct fit. Certain compounds that run wider-than-average may require front negative camber.
235/40-18 tires can be a direct fit, but we strongly suggest dialing in front and rear negative camber to prevent rubbing. Amount of camber varies depending on tire brand and ride height.
245/35-18 tires require at least -1.5 degrees of front camber, and -1.8 degrees of rear camber depending on tire brand and suspension setup.
255/35-18 tires require at least -2.2 degrees of front camber and -1.8 degrees of rear camber depending on tire brand and suspension setup.

Front & Rear: 18x8.5" ET45 with 225/40-18 tires
Front 3mm or 5mm spacers required for suspension clearance. Certain aftermarket suspensions may require larger front spacers. See below.
235/40-18 tires require 5mm front spacers.
245/35-18 tires require 5mm front spacers and at least -1.5 degrees of negative camber.
255/35-18 tires require at least 10mm front spacers and at least -2 degrees of negative camber.

If I was doing a 255 square set up I would look for 18x9et50 and use a 15mm front spacer.
Will be tight on the front but could work, but I havent tried it.
I assume this is for track so you probably want a decent amount of camber anyway.

These are Arc8s in 17x9et42 + 5mm spacer on the front with 245/40 A050 R comps and -2 camber.

YES!

I think what's posted here so far mostly applies to stock height F22s. Plus, note that tires of the same size can vastly differ from one manufacturer to another, and even from one model to another.

255 square (and even 265s) are definitely possible, but most, if not all, are lowered on coilovers with fenders rolled and more negative camber.

Understood, but I'm looking for a wheel that I can rotate to do so. No spacers if possible.

This looks perfect to me:

^ That's f22_shayan. I'm sure he can tell you more about his spec, but he's on coils (KW V2) and no camber plates.

Nugget · 11-01-2018, 07:29 PM

I'm on Ohlins with camber plates.
Those 245s are bigger than a 255 road tyre.

You aren't going to fit big tyres on a square set up without having to use front spacers.
You could do 18x8.5et40 but it would be a compromise in the rear.

Compromise in the rear how? (I'm serious, I don't know)

A higher offset (eg et50) will make it be easier to fit big tyres in the rear, but will need a spacer to clear the strut on the front.

So why not do a ET50 Square and run 255? I don’t mind if it pokes a bit.

Nugget · 11-04-2018, 07:47 PM

I feel like we are going around in circles.
That's what I recommended, but it would require a spacer to clear the front struts and you said you didn't want spacers.

Hey, I appreciate the advice you have given so far - I know nothing about wheel offsets. Your advice is 18x8.5 ET3X would be the best fit without a spacer and could run 255s. THANK YOU.

Just so I understand, Running a lower offsets or running spacers would cause it to poke- right? What is the lowest offset I can run, even with a little poke?

hey yea thats me! back then i was on V2's without camber plates and didnt have much of an issue with Rub, i had the federal 595Rsrr's (245/40/18 squared) which ran very wide. if you want to run that size, try and get about -1.5* of camber and youll be fine.

now im on TCKline double adjustable coilovers with TCK camber plates (-2.8* camber) with squared 245/40/18 NT01's

Have any leads on a lightweight 17x9et50? 17x9et45 seems much more common.
