HELP, Koni Yellow or FDS

hey guys i have an e90 with eibach pro kit springs on it and i love the drop, however it has been a few months on them and i am ready to get some shocks to get a better ride quality out of them for daily driving. I do not track my car and dont care too much about the adjustable feature. I just want the the set of shocks that gives me best ride comfort. I have come down to a choice between koni FDS or Koni yellows, recommendations please . . .

Even if you don't track the car, the Koni Yellows will be smoother than the stock OEM setup and the stock OEM sport setup. Even with the runflats on, you will notice car taking bumps, potholes and expansion joints very nicely.

I can't comment on the FSD, but some members have mentioned similar comments as for the Koni yellows.

I was in between the two also but decided to go with the sports yellow because of its been out longer and it has a proven performance record; you also get adjustability as an added bonus; plus, the vendor I went with actually recommends the yellows over the FSDs even though the FSDs are more expensive.

FSD's are wayyyyy more comfortable.... they are perfect for the street especially if you have the prokit. If riden in a car with the yellows and the FSD's. The yellows are great if you go to the track and like the ability to adjust the shock. But hands down the FSD's have the most ride comfort.

Koni FSD's are the ones you want for the comfort. They were designed with the stock springs in mind and have adjustable dampening.

If you want a sportier suspension setup go with the Koni Yellows, they are great shocks (my personal choice but from sound of it go with the FSD's they are what it looks like you want to get).

As stated, the FSD will give you the most comfortable ride. For a sportier ride the Koni Yellows are the way to go. Let us know if you would like a quote on any of those.

I had Koni Yellows and H&R sport springs installed today and what surprised me most was how the ride actually improved. The stock sport suspension is extremely harsh, especially given the poor quality of the handling. The Konis give you very accurate feedback without jolting you over the rough stuff. (And needless to say, the Konis improve the car's handling immensely.)

FSD, not FDS.

As per comments above, FSD provides more comfortable ride when not driving hard, but they stiffen when needed.

That's the amazing reason why the FSD is one of our top sellers for shocks. I think it's an amazing technology that everyone should take advantage of

I just installed Yellow Konis with an existing set of Dinan springs.

Compared to the stock shocks...night and day difference. The stockers showed no wear on removal, but simply could not keep up with the much higher spring rates.

The car would "CRASH" over pavement joints and would bottom on large bumps. Lowered springs demand serious damping control from the shocks!

Initial Koni Settings:

Fronts at Min Firmness
Rears at 1.5 turns = 3 out 4 firmness

Results:

Ride Much Better, but still bouncy on small bumps. Basic road irregularities.

Current Settings:

Front 1 Turn = +1
The Rear is 3.5 out of 4 and rides very controlled and firm but not bouncy.

I would suggest the Sports. The FSDs lack adjustment and it seems you need to match the spring rate to the shock damping.

Just got back from 2 days of HPDE (Track). What an improvement! The Koni Yellows were perfect, with minimal body roll.

Does that mean they are not as well suited to lowering springs as say the yellows ?

Havent I seen somewhere a Koni/Eibach kit endorsed by Koni ?

The FSD's are made for the eibach pro kit...valved accordingly...

that being said, I would have to disagree with statements saying that the koni yellows give you a "sportier" ride than the FSD...

Heres the difference:

Koni Yellows are slightly more adjustable, but ride harsher at all times
Koni FSD has no adjustments, but has a more comfortable ride on a daily basis

the FSD handles just as sporty as the yellows, just doesnt let you feel the bumps as bad in the slower areas with less pushing since its a dual valved shock...in other words, its a better shock in general, its not a less sporty ride, its just a more refined shock, with same/better handling characteristics vs the yellows
