Lack of rear end grip.
Hi guys. Is there anyone else than me who feels that the rear end is "loose" on these cars? It doesn't require much until the traction control hits in. I have no confidence in the rear end and it feels like you have no real trust in the car when you drive it fast without traction Control or MDM. I had better rear end grip in my old 335i it feels like.. The car doesn't communicate well with me when it's on the limit of grip. As soon as you give it some throttle out of a corner traction control or MDM goes in instantly. just like the Michelin supersports are 15 years old or something.
I was thinking about changing my suspension to Bilsteins EDC B216 kit to see if that helps but i don't know. The car feels scittish at the rear as it is. Anyone else who feels the same? Any solutions to this "issue"? Johnny Last edited by M 4 FUN; 06-13-2019 at 04:05 AM.. |

Are you rolling on the throttle or jabbing at it? Rolling on the throttle helps a lot as it decreases wheel spin a lot.
Also -- check your threads on the tires. Are they corded? |

Are you a ZCP car or early build? If so pay for the coding its a night and day difference with GTS rear diff. Seems like the ZCPs were tuned to be hooligan mode.
Also traction control kicks in very conservatively not necessarily when you're at the limit. Get that coded to something less aggressive as well and the car feels 1000x more capable. The car is seriously held back stock and feels just as you describe. |

I also feel like the BMW star spec MPSS are a major let-down I have sets of MPSS on other vehicles I daily drive and the difference is astounding. The BMW spec ones seem to have almost no grip in comparison. |

What you are experiencing is BMW's poor chassis and shock tuning , which then requires a super conservative traction/stability & MDM systems.
I'll get a lot of hate for this but the rear answer is getting away from the F platform and moving do something like this...

Yes, it's slightly faster on some tracks but it's still too big for me and i am not a Camaro guy. I'm not a fan of the looks either with the high body panels and low windows. I like my M4, i just have to do some diff and MDM flashing . I see you run Öhlins R/T suspension on your M3. Do you like it?

The Ohlins had their pros and cons. PROS: they settled the rear-end and took ALL of the nastiness/instability out under all conditions whether it was braking or cornering and hitting a bump mid-corner. CONS: While the low speed and small bumps were smoother over stock because of the DSV technology , the bigger bumps were very jarring. Some bumps and dips on the freeways near me would cause me to lift out of my seat and set off the traction control system. It also still doesn't fix the rear traction issues or the MDM that still is very intrusive.

After having it almost a year now , it it one of the top 3 performance cars I have ever had. The 1st being my C5 Z06 , and the 2nd being my tuned Audi TTRS. Regarding the weight, it drives much lighter than its weight suggests and feels lighter compared to my M3 when tossing it around the corners. The M3 felt quite a bit more top heavy over the SS 1LE, despite the M3 having the carbon fiber roof.

Ok! Thanks for the Review of the Öhlins suspension. Ok, the American made cars have really shaped up over the last years, that's for sure. Good performance for the Money, no doubt. |

Stereotypes are a rather ignorant and narrowed minded thinking process. That's like saying because you drive a BMW, you are a preppy douche bag who drives like an asshole. If you are basing decisions on stereotypes and not facts/reality then you are missing out on some gems. Tunnel vision thinking is never a good thing.

Traction issues
I know it doesn't fully address your questions but this is my suspension and what I think of mine. After I installed Coilovers, Camber plates, Toe Link, F/R Steel bushings, Rear suspension link kit, a proper ride height, F 275,/R 305 or 285 square tires and my car feels great. I have no complaints during hard acceleration, braking and wild turns. I suppose you have to spend some dough to make it perform the way you want it.
