Kinda surprised that nobody has mentioned a good alignment yet. Having all the wheels pointed in the right direction helps quite a bit.
Doesn't add grip or remove the need for driving skill, but the car tends to go straight more often under acceleration, IME. |

https://f80.bimmerpost.com/forums/sh....php?t=1056851 https://f80.bimmerpost.com/forums/sh....php?t=1003463 BMW's solution in later iterations was to tune it to be more back-loaded and add larger wheels in Competition Package but that all goes out the window once you add back some power or remap the boost. It's what it is and certainly the reason the next generation M4 will be offered with an AWD option and sadly, eventually without a manual transmission, in an attempt to electronically harness the power output. |

Put at least 295s on the rear. Until then modulate with your feet. Look at lap times of these cars before and after ZCP came out and there is clearly nothing squirrelly going on. On the '15 and '16s with original software yes, squirrelly, after that almost too tame down low with BMW's re-map...the CS is a well-balanced machine.

I don't know what y'all doing with your right foot. Or you've got greasy roads that you don't know about.
I just got back from a cold winter drive, did a WOT 1st-3rd gear pull in MDM mode and I had no squirrelly ass. Actually amazed at the level of grip. It was wet and zero degrees Celsius outside. Stock non-ZCP 6MT on snow tires (640M & 255-section Goodyears). I have seen DCT cars fishtail a bit because the 2nd and 3rd gear shifts are aggressive and if the road and tires are cold, there's gonna be some sideways action. Can be seen here at 1:50.

Correct, you need wider rims to accommodate wider tires, so you cannot use wider tires on stock rims, and I also love the stock rims on the M3 CS. And that's EXACTLY what I have been thinking, if I ever owned an M3, or any high horsepower car for that matter, I would probably buy some Sport 4S's, as Sport Cup 2's are a step too high IMO.

I would agree with the OP. My M3 Comp seems pretty squirrelly when the rear loses traction in a straight line. It tends to snap sideways. I've driven a lot of high hp rwd cars and some will stay straight when the rear tires start to break traction, and some, like the M3, tend to snap sideways. I tend to think its the e-diff doing that as opposed to what a standard mechanical lsd would do. It's probably the only thing I don't like about the M3.

I started with ZCP and it was typical M3/4 hooligan. The CS felt part hooligan and part serious about hooking up. The GTS feels very serious about hooking up and when the back end does step out; it does it in a much more relaxed manner. I feel the car should have come from the factory with this setting. The car now feels like a proper sports car and not a muscle car with more power than the chassis can handle. With a tune and I can now get to full depression of the gas pedal in second.

Actualy you did not. With full DSC, the electronics do a fine job of keeping the rear end in check

I comfortably fit 305 rear tires on my M4 with room to spare, as do many other owners. Some managed to fit even wider tires.
