I'm fairly certain that I'll be purchasing a set of APEX wheels here in the 1st week of march in the group buy. My question to all you fitment gurus is as stated in the title. I'm running a stock suspension M3 'vert and I've already decided to stick to 19" wheels, but I'm uncertain of the size to run for the wheel.

My question is what are some of the disadvantages/advantages of running a squared set-up vs a staggered. APEX recommended that I could either run a squared 19x10" ET25 with 275/30/19 on all fours...OR 19x9.5 ET22 + 19x10.5 ET22 with 265/30/19 and 286/30/19...

Also what kinds of tires to run with each? I tried to look up PSS with the staggered set-up, but I couldnt find any in the 285/30/19 configuration...

Any advice? Thanks in advance,

AP

I'd like to know as well. Subscribed.

You will have more tire choices and cheaper if you go square set up in 18x10 et25. Advantage of square is that you can rotate tires to any position as they wear which is a definite plus for track use. Also square set up will dial out some of the understeer inherently built into the the cars suspension set up.

For mostly street use, I shouldn't notice the staggered vs sqaured should I?

Also in the aesthetics category, am I really going to notice the extra 10mm in the back or am I going to notice the fronts looking significantly wider more?

For street use you most likely won't be able to tell between square and staggered. Looks wise you will notice the front being wider more than the rear. There is more room out back so extra width isn't seen as much. I personally like the purposeful look of wider matching fronts and then you also get deeper concave if you match front and rear wheel as well.

I'm almost certain im going to go with the squared setup! I like the deep concavity and it'd be nice to ahve the same depp concavity on all fours. Plus I can finally rotate the tires...

Good call do a little more research on tire width, 275-30-19 will be close to rubbing up front.

I'd read in a bit more on the gurus before I'd go squared. There is a reason to why BMW have designed with staggered. Changing the width ratio front vs rear will impact under/overstear. There are a few good threads on this where people discuss their experiences.

Cheers

Bump. Any new advice? Staggered or Squared? Will 275/30/19 rub at all on stock suspension?

[jnathan68]

As others have pointed out, BMW, and other manufacturers, go staggered for multiple reasons (looks, handling, cost) and changing to a square setup will affect steering feel and handling. How much it affects each will depend on tire size, tire type, type of driving being done, etc.

Going wider in the front to match the rear will increase front grip and cause more rotation (over-steer).

Sorry, can't help with exact fitment but I am sure there are others who can chime in.

[imserious]

I wouldn't worry about handling changes in street driving. You won't feel it unless you drive like a maniac.

For the street, it's a matter of aesthetics and ability to rotate tires.

Handling will change at the track.

Has anyone gone square w Apex Arc-8's? Just purchased a set of 19x9.5 ET22. Going to mount them once it gets warmer. Going to drop them a bit on springs (probably swift) then too. I'll want to be as flush as possible. Any recommendations on tire sizing to not rub? Currently rubbing on my stock 220's & 265/35/19 Blizzaks & 15mm spacers all around...

I'm on 18x9.5 ET15 265/35/18 PSS's square.
On my E46, i had to dial in some major camber in the front (w/ camber plates) to handle this setup.
The E9X takes the 9.5 square much better; currently on stock suspension with springs & rides/drives well.
You'll be fine.

Good thread. I'm one of those odd people that like the stock 220's. Is anyone running a square (rear) set-up using these wheels? I'd like to see pics as well on the car if you are...

Bumping this in hopes of not having to start my own thread since I posted in here.

I have the square 19x9.5 ET22 Arc-8's. I didn't go with Swift, but ended up going with KW height adjustable sleeves. Will have them pretty maxed out if not completely, particularly in the front. Additionally will be looking to be as flush as possible so I might run small spacers unless I feel like I don't need them.

I have two Continental ContiSportContact 3's in 265/35/19. I don't want to be rubbing but currently on my stock 220's in that same size tire, I am rubbing at stock height & spacers. I want to run the tires square too for rotation convenience. Do you guys think I'd be good with that size tire in the front & back on the Apex's?

Is it possible to run staggered and change the setup of the suspension to dial out the understeer? Pretty sure must people who are worried about the understeer will be going on track and will have coilovers fitted.

Yes you can try but tire width seems to be easiest. You can change tire pressure, front bar stiffness, rear bar stifness, camber, spring stiffness, shock stiffness or aero to effect front rear balance also.
