getting tired of ride quality.

so about a year ago i put h&r sport springs on my 06 330i. looks wise great. but the ride is horrible.

since i already have the springs should i replace the shocks with koni fsd?
or would i have to buy the whole kit?

i might just say f it and put back factory springs back in. but its so high!

Shocks are probably at the end of their life with the H&R. I don't think the factory springs will solve the problem

You need some aftermarket shocks that can handle the shorter, stiffer H&R springs. Koni Yellows or FSD would be perfect.

FSDs are not for lowered springs or stiff springs. Some ppl differ. Yellows can be adjusted to suit the comfort level/handling you desire.

FSD's are actually designed to work with Eibach Pro-Kit. Koni and Eibach partnered on them.

However, you are right, Yellow at the softest setting will be much more appropriate for someone seeking a comfortable ride.

Also, don't get coil overs as some others have suggested - they will not help your quest for comfort at all.

Call us up we'll make sure to get you squared away and happy

Koni Yellows are the way to go. You can install and forget, but if you ever want to adjust them, you have that option available to you.

If you prefer the external adjustable rear shocks, they are available through us. The standard Koni Yellow is only standard adjustable, you will have to remove the rear shocks from the vehicle to adjust them.

Interesting that the yellows get the positive vote, compared to the FSD.

Are we really comparing 'like for like' and not 'apples and pears' here? I researched this subject before fitting the FSD, to keep or even improve the primary ride quality, while getting a better secondary ride quality.

Someone explain how a yellow, on a soft setting, is a better damper (shock) and gives a better primary ride as well, compared to the FSD.

Not saying it is wrong, as damping feel is very personal like tire choice, just what's the reasoning and rational for the Yellow?

opaque18: I can highly recommend the FSDs, as you've seen on the other thread...

HighlandPete: You have to keep in mind that many of the forum members are biased towards lowering, sharper ride, and less comfort...

Also, the Tirerack review does compare the FSDs with Yellow on full-soft:
http://www.tirerack.com/suspension/tests/koni_fsd_b.jsp

The FSDs were more comfy AND performed better on the track! Not sure why anyone would buy yellows to put on full-soft setting, aside from ride height.

The Tirerack test was one of the key reports I read back in 2007, when looking to get FSDs.

Personally I don't think too many really get what the FSD is about, it isn't really a sport damper in the conventional sense. It's a clever design to give a better ride quality, without sacrificing the handling. The fact it can separate the two functions, can mean damper valving to improve the handling in some applications, that is a bonus.

But from my perspective, once you go for lowering, you start compromising the main purpose of the FSD, as reduced suspension travel, higher spring rates are eroding the working parameters and benefits of the FSD, and other damper designs come more into play with those changed and more sport influenced parameters. Originally Koni didn't recommend FSDs with any other spring combination than OEM. Since changed, but at what compromise?

Simply put, IMO, the FSD sits in a different market sector, than the traditional sport damper.
