I remain highly skeptic to a system that relies on two components (springs and dampers) working in tune where only one of them is adaptive. After this discussion and Racer20's inputs though I will try to drive both before ordering which I wasn't going to. Let's see how communicative,predictable,consistent and strong this latest active setup feels. I have no doubt it will be smoother.

Does anybody know what variables the EDC on the E9X M3 controlled? Was it just compression and rebound damper tuning?

So, if springs, bars, etc. all stay the same and only the shock valving is changed, then it's going to be difficult for more than one setting to truly be optimized. At least, that's true based on the somewhat limited suspension tuning knowledge I've accumulated over the years.

Adaptive systems know the spring rate and mass, and can figure out the excitation frequency from the sensors on the car, and apply the correct level of damping in order to achieve critical damping on a wider range of road inputs. Adaptive systems come one step closer to being able to provide true "skyhook" control (imagine the body of the vehicle being connected to the sky and remaining flat and level, with the wheels perfectly absorbing bumps under the car) Mercedes magic body control is yet another step.

Is the M Adaptive suspension worth it?
Ive got a deposit down for the first order spot available for a M4 at my local dealership. They asked me to circle all the options I want and i'm not sure if the Adaptive suspension is worth adding?

Take my word on this, go and rent a dodge minivan for 2 weeks, and then all you will be thinking about are suspension, transmission, hp. I think I will never ever complain about a car again, but as a learning experience that was priceless. |

I've enjoyed it on my 2011 E92 M3. It's definitely a little jittery in the firmest of 3 modes. Nice to leave it on comfort when just cruising and firm setting for spirited cornering.

Can the Adaptive System cope with these changes or does the Adaptive system Fails ? |

The car will not behave as BMW intended anymore. You may or may not notice the trade-offs, and you may or may not like it. The closer you stay to stock ride height and rate the less likely you are to mess things up. |

With the coilovers I can then fine tune to perfect the cars handling capabilities. I have read all your post and understand what you have stated about the Adaptive system, But do you think this system will out perform a good coil over system? And if I to change the spring rate to lets say going harder then stock do you think the system will cope with the change or will all the sittings get a little firmer. |

There's no way to know how the algorithm is tuned and what it is or isn't capable of accommodating, nor do we know how much headroom is left in the damper itself. I also don't know what you mean by "outperform." Laptimes? Fun-to-drive? Ride quality? The FACT is that an adaptive system has much wider bandwidth on the ride and handling spectrum than a passive system. But it'd designed around the stock chassis and spring rates. If you want to go beyond that, you could probably find an aftermarket coil-over set-up that will provide better laptimes, but you will loose the bandwidth that allows for a good ride comfort. The only way to know for sure is to buy the springs and try them, and if you don't like them, sell them. You wouldn't be out that much time or money.

Wouldn't the weight transfer reduction offered by stiffer springs be in fact negligible?
I understand that there is a slight weight tranfer that occurs when the car rolls due to Cg moving about the roll center. But IMO, this amount is negligible compared to the weight transfer generated by the cornering forces. Last edited by CanAutM3; 03-30-2014 at 04:23 PM.. |

Racer20,
How much more aggressive will the Adaptive system be over the standard. Lets say Adaptive in sports plus setting, will that be same as a standard passive suspension when it comes to handling, body roll, rebound. If not what setting will be close to a standard passive system. |

Now there H&R Sport and Sport Plus springs for the M3 e92 EDC suspention. Will it be better for the M adaptive suspention to install the lower springs?

Racer20... Got questions.
Do adaption damper systems typically adjust each damper individually? If so, does the control system look at yaw rates and include that factor into adjustments that are made? I been searching for stuff to read to get a better education on this and haven't found anything but basic marketing information. Do you have suggestions? |
