ZCP not riding correctly

[BayBayBay]

I bought my car in Dec 2010 and have about 7500+ miles on the car right now. It wasn't until recently I noticed the ride has gotten ALOT softer regardless of what EDC setting I have it set on. The car seems to have lost the stiff sporty ride that I am used to and LOVE.

It's really bugging me that I don't know what is wrong. I mean there's no error messages, TPM is reading all tires normal, but I know it's not riding like an M3. Even passengers have commented on the softer ride even though I haven't made any changes to the car. I'm still running the stock DUNLOPs, does anyone think these have anything to do with it?

I'm hoping someone has experienced this and can shed some light. My next move maybe to call into Peter Pan BMW service dept.

Thanks team!

Wanted to add, I am noticing it varies day to day, and I drive the same route to work every morning. I promise, I'm not crazy. Maybe dynamic suspensions are not for me?

Nothing happened to your car in that period of time...... besides if EDC malfunctions it goes to full stiff and becomes very uncomfortable.

M3's ride very well, even with EDC. Don't confuse this with there being a problem with your car, just realize that BMW really nailed the ride/handling compromise with this car!

I hate to say this but it is all in your head, your car is fine!!! Nothing can go wrong that will make your car ride smoother, it is working properly!!! Even with Eibach springs in my M3 it rides quite smooth and dosen't hit hard at all.

Using my digital Accutire gauge, it reads 31.5 in front and 34.5 in rears

Bump it up... I run 34 front and 35 rear and responsiveness is better. I bet the perceived softness is froM running pressures much below the recommended level. 3 to 4 lbs more makes a huge difference. The pressure you are running is better for track performance than street responsiveness IMO.

I will give this a shot. I know a lot of people are thinking, "It's all in your head" - honestly, I'm pretty positive it's not, and I can also say, I have experience with dynamic adjustable suspensions on other cars sometimes not being consistent from every startup of the engine.

Reading the sticker on my driver's side door panel, it says 34/36 when cold.

That is correct... kmarei just had a few too many glasses of wine tonight

Any pressure recommendation “cold” is difficult to interpret, and is only a starting point. The difference between cold and hot could be 2 pounds, or 10 pounds. I have found most street tires suit me well at around 38 all around, at operating temperature.

After adding a little air to the front tires to match factory specs I still continue to feel the same cushioning softness of the ride.

Bump it up some more then. I don't think tire pressure is your problem, but there is nothing sacred about the recommended pressure. Up to around 40, it's just personal preference.
