I've looked into it, but i want a 265 rubber in the back, and i couldnt make that work in the front without making modifications to the car that i do not wish to make. also, i've read that since our car was engineered for the staggered set-up, switching to a squared setup without making changes to support that setup isn't favorable for handling? wish i could remember where i read that. just some food for thought.

Only downside that I know is you will need to use spacers and negative camber (shims, pull alignment pins or camber plates depending on tire size). Spacers for clearance in front or to flush the rears.
Going 18x9.5, 265/35's myself.

Two potential advantages to going square:
Reduced understeer Ability to rotate tires (even tire wear) Issues usually revolve around having enough room to run this type of setup. The Z4M has the E36 front-end, so IIRC other threads on this you can't get anything like a 265 width to fit-255 probably does with some tire/wheel combos, but ability to set camber is somewhat limited then due to space IIRC. If tire wear is an issue, then I think agree with The Hack (other thread) where he states that you don't really save as net wear is pretty much the same--the difference is you replace 4 tires less often rather than replacing 2 more often. Understeer can pretty much be managed with camber settings, and I'd rather go that route personally as it facilitates more even tire wear (assuming you track or auto-x a bit, or like to canyon carve). I seem to recall some folks saying the car did not handle well square and it really wasn't designed to run in that config. Eccentric--what requirements are you trying to fulfill with a square set-up? |

I'm currently running a squared setup for track days and I can say that it reduces understeer significantly. I'm running volk te-37 18x9 et40 with toyo r1r 255/35. But for DD'ing, I'm not sure if it makes any difference. Also, I prefer a staggered combo for street, since it looks way nicer.

i run square, only because i'm too cheap to have 2 different sets for street/track. great for auto-x. i don't even bother to rotate considering how the back right will always pick up the nicks/rash and last thing i want is to spread the damage to 2 wheels lol. i dont drive anywhere near the limit on the road so it's not noticeable. but to cmark8's point, i do run spacers on the rear for aesthetics when it's not tracking.

Thanks for the input guys

I wanted a setup^2 for 3 reasons: I think it has great aesthetic appeal; I originally thought it would be nice to be able to rotate the tires; I wanted to reduce understeer. But it seems, as you mentioned, that all of my reasons, other than the aesthetic ones, could be satisfied in other (cheaper) ways. |

re: the car not handling as well as it was not designed to run in that config, the counter argument to that would be the e36 m3 which originally did come square until people started complaining about the back end coming out so bmw changed to staggered.

if you're going to change the suspension then you're pretty much reegineering the set up. squared will make the car more tail happy but there are ways to remedy that. try to balance it out with other mods.

The car is a totally different beast with with the front camber at -1.5 and 1/16 toe-in (vs. the max stock -.9 we could get--lots of push with that). No rollover at the track last weekend--and I think as we improve our driving skills we'll take things up to -2.+ front (not good enough IMO for those settings yet). -1.5 front is pretty good for and aggressive street set-up. Even as a DD we get pretty even wear up front (toe is key there) since the car sees some back-road use. The Hack gives a great suggestion here on how to use these as "adjustible plates" for Auto-X or Track. Certainly worth a try IMO given the minimal expense (but it doesn't provide the cosmetic appeal of course). |

I'm also interested in the square setup to allow for tire rotation because I'm trying to be cheap.
