Going square - 18" or 19"?

DemonicAW · Wed, Feb-22-2012, 02:17:19 PM

Looking to do my M3 over this spring, and I really want to go to a square setup. I know I am going to get the "do a search" but honestly the search function sucks and I've been researching this for days and can't find a definative answer. I am currently running OEM 18's which are 9" wide rear and 8" wide front correct? I have 225 tires up front and 255's in the rear. This car is my DD, ~10k miles a year.

My goal is either a 9.5" or 9" wide square setup, I really really love the look of 19's so I would like to go that route, but is the ride really much worse than the 18's? I am currently on OEM suspension, however I am most likely going to go with the Status Gruppe tuning coilover's with camber plates.

Are camber plates are necessary for a 9.5" square setup for both 18's and 19" rims? Or just the 19's?

I would like to get wheels with the same offset so I can rotate tires in the summer, although I understand spacers would be needed in the rear for this.

I'm leaning towards the Sportline 19" CSL Reps 9.5" all around and wrapping them in Hankook Ventus RS-3's or Mich PSS at 265/30R19 with the SGT coilovers, 10MM spacers in the rear. Just unsure of the offset, if this will even fit, or if its too aggressive a setup for a DD. Any opinions, pictures of your setups, and advice is very much appreciated!

Running OEM 18" squared with 12mm spacers in the rear. I need coils though.

If your going square you are doing it for track performance. If you are doing it for track performance, then there is no question go 18.

all of that.

I was just about to ask if this car will see the track. If not, Im assuming you're trying to save money on tires?

Heres a back shot of what it looks like. Getting ready to get back out to VIR

◘ 18'' is the way to go!

Not to be a jerk, but clearly you didn't search. The square set up phenomenon has been the most discussed topic for the past year.

19's look great but are heavier, harsher ride and cost more for tires.

18's have more tire selections, cheaper in price, weigh less, more track oriented, and obviously look a touch smaller.

You can fit a variety of square set ups on this car, 18's or 19's ranging from 18x9 - 18x10 & 19x9 - 19x10 respectively.
Tire sizes can vary from 255/35 to 285/30 all around.

Fitment depends on offset, ride height, and camber specs.

Yes the Sportline's will fit with that set up you mentioned.

OEM 18x9 Square

Apex ARC-8 18x10 Square

ZCP 19x9.5 Square

How's that for not having to search?

why are 18's better for the tack?
