Non-staggered tires - affects handling?
What will changing to a non-stagger tire set up do to the handling?

More oversteer. From purely racing perspective that makes the car more balanced, but in hands of less experienced drivers it would be easier to fishtail with that setup.
Most street cars are setup for excessive overstreer to make them more safe. |

So the wider rear tire provides more patch to keep grip? |

[*]Under steering is when the front end of the car slips or looses traction in a turn (figure A). In other words, the front of the vehicle is plowing (still going straight ahead). The front tires let loose first and the vehicle does not steer the way you want it to steer. Over steering is where the rear tires break out first, the rear tires are swinging out, and when you apply the brakes, it makes it even worse. [*]Most automobile manufacturers design for a certain amount of under steer because it is safer for the average driver.[/LIST]

I think in other countries (not US) you can get sport suspension with non-staggered setups; I don't think it makes any difference
I think BMW knew US drivers would spin out of control if they had the sport suspension and regular width back tires |

Oversteer I can handle, understeer blows! Maybe I need to stay staggered and deal with the tire wear? |

This seems to have gotten a bit confused. Let me take a stab.
Understeer, car tends to initially plow when reaching cornering limits. As stated this is typically 'engineered' into a car as it is considered safer for most drivers. The smaller front tires, or staggered size, is one way that BMW, Porsche, and others dial in this tendency. Oversteer, car tends to lose rear end grip and come around when reaching cornering limits. As stated, this typically makes the car feel more balanced during hard cornering, but does take some driving skill to utilize correctly. Eliminating the staggered tire sizing will induce the car to display more of this characteristic during hard cornering. Which is better? Personal taste and driving style dictates that. My .02, in general staying with the OEM staggered setup will not reduce the quality of your driving experience of these vehicles. If you insist on trying to drift through every freeway on/off ramp, you probably would prefer matched sizes. To each his/her own. |

I was looking more toward tire rotation and tread wear! Thanks for the info on what to expect. |

the car seems to not have much of a problem with initial turn in and seems pretty balanced, ad you can always give it some throttle to make it mid-corner loose

Heh im guessing normal everyday driving shouldnt include any form of under or over steer....
Unless you drive like a race driver on the streets, then again what streets have room for this? I am in qeues on my way to work in the morning and on the way home, so im pretty much getting the E92 for the looks, quality, image, and comfort of the ride basically. |

Spirited driving and racing are different! If you got the e92 for only those reasons, IMO you are wasting one fine engine! |

just wanted to restate. a equal tire width at both ends of the car will contribute much stability during off-throttle cornering. The staggered width is more for on-throttle with a wider contact patch allowing more grip to power out of a corner. |
