Second, after driving my car for almost two years and doing some mods (and going back) I really don't think the springs/dampers on this care are too "soft." Yes, the car has some excess body roll from the factory, but that is a swaybar issue, not a spring/damper issue. The stock dampers/springs do a nice job of allowing you to feel the road while still being able to absorb bumps. A mistake a lot of people make is that a well tuned performance suspension needs to be bone-crunchingly stiff in order to work. I don't agree with this -- it assumes whatever you are driving on is as smooth as glass. Roads are never this smooth, and frankly, most tracks aren't this smooth either. The 4 I've been to in SoCal are varying degrees of smoothness. A very, very stiff suspension will hit a bump and get upset, rather than absorb the bump. It's a fine balance, but people frequently tune their car with the goal of "as stiff as possible" when it doesn't really make the car any faster -- it just makes it slower (much harder to handle in real-world conditions) and less comfortable.

What I meant on my original comment was that some people swap springs to aftermarket ones without even knowing if they are even going to a softer springs |

However, I think it might be difficult in the spring department because (as far as I know, could be wrong) most OEM-style progressive springs do not specify their spring rate(s), perhaps due in part to the fact that the rate changes based on compression. That being said, I absolutely agree that a baseline metric would be super helpful. Something, anything so I can determine if the spring I am buying is objectively softer or stiffer than stock.

all the bump stops do is allow the shock to travel more, which to be honest is out of there spec. I ran the hr springs, and the ride is rubbish. The dinan work well on stock edc.
If you want more of a drop you really need coilovers. When I switched to coilovers I could not believe how much better the ride was. It felt so much better. Quote:

On oem dampers, sure you'll shorten the damper life, but then this always the case with aftermarket springs. To be honest, I'm not sure about the internals of the oem shocks to know the limits of the workable travel. Anyway, so far so good with my combo and I prefer a solid damper/spring combo to a set of coilovers any day.. Richard |

That is certainly not true. Spring rates definitely affect how much body roll there is in a car. Comfort, and absorbing bumps aside, if you're talking about controlling the yaw dyamics in both lateral and front/rear shift, then stiffer as well as shorter springs will reduce this.

New member here, after looking at some of the horror stories in this thread I don't know if I want to lower the car, which springs to choose or if I would trust any shop to do it. I had all my cars lowered in the past including a 95 BMW and seems like lowering these new BMWs are a problem for a simple spring installation ....
