I don't no much bur what is the big difference
If any between a square fit or staggered fit on my m3 what are the pros and cons thanks in advance

Square setup, assuming it's achieved via larger fronts, will increase your front grip to dial out some understeer. It would also allow you to rotate your tires (I recommend only front to back, not side to side).

Staggered looks cooler to some people and is part of the built-in understeer that BMW puts into its cars, which they do because they want to minimize incidents of people who don't know how to drive buying their cars, turning DSC off despite not being able to drive, and then going careening backwards off the road and giving BMW a reputation for building death traps.

Seriously though, while dialing out understeer sounds cool and everyone loves more grip, understeer is built in because it's an effective early warning system that you're exceeding the grip limits of the car and possibly just plain driving poorly, and losing grip via understeer is far easier and more intuitive to recover from than oversteer -- so be honest with yourself as to how good a driver you are before you start down that path. For example, have you attended several track events?

Looks like not a good idea then I dint have any pro training just what I have learned over the years

In that case I would recommend just sticking to stock sizes. Square setups are found more often at the track and are typically accompanied with different wheels. I'm not sure if the rear-size 265/35 tire would fit safely on the stock front wheels. The answer to that may also be different depending on WHICH stock wheels you have.

I'm not sure, but there are several threads about tire sizes where people mention the wheels they're using. Also, ZCP 19s are wider than non-ZCP 19s, so that will come into play as well. I'm actually just starting to look into a square setup myself for track use only and am trying to see what's possible on which rims. I'm sure the information you're looking for is in various threads around here.

Im going to keep looking around n I'm just going to put these up for sale or trade see what I get

IMO, stay staggard with this car. It doesn't understeer nearly as much as most other BMW's. The tail WILL come out pretty easily.

Yea I'ma stay staggered now just need to get rid of these for some new ones cuz don't think I can find a staggered fit good enough with these ones
