View Full Version : Koni FSD or Sport..... hmm.

I know that the FSDs haven't been out that long so I'm wondering what the general consensus is on whether to go with Koni Sports or Koni FSDs is.

Anyone ridden in cars equipped with both that can shed some light?

I like the idea of the FSDs... I am a commuter and I don't track my car. However, I love me some spirited back roads on the weekends. :eek:

So, I'm looking for a buttery smooth freeway ride with great corner manners when pushed.

Your sig says Koni FSD in it.

?

I have OEM sport and FSD to compare. I like the FSDs quite a bit. It always surprises me how nimble my car is when changing lanes, turning, etc.

I can get some body roll on the highway if I swerve hard, but the stock sways are still on there. I think if I had the Eibach sways, my suspension would handle exactly how I want it to. If only I could get that ride height down with some Intrax springs, it would look how I want it to too!

The sport struts, IMO, were very good. They just don't last. They were a great blend of comfort and sport. I think the FSD is even better at it. I am a commuter, almost all highway, but I tend to seek out backroads too. I often drive to mountain bike trailheads as well, and those terrible roads really show off the FSDs. To me, if feels like they are generally a sporty shock, but when you get up to speed or if you are on bad roads then they soften up. The change is instant.

I am curious what Koni Yellows feel like too though, so I would love to hear what feedback you get here!

ps- if you are up in the midwest ever (!) drop by for a test drive.

Good info. Yes, I was updating my signature with my latest purchases. :) The FSDs fell through because.... well, I won't say his name on here. Let's just say that he didn't get back to me so I sought an alternate vendor. As soon as I did, this thought crossed my mind. Am I buying the right thing? I'm still leaning towards the FSDs (heavily).

You'll see that my signature also says M5 sway bar. That is purchased and on its way.

totally agree .. best of both worlds without doing any adjustments .. feels like it does it automatically .. FSD's will suit your needs and if you really want to take it to the next level .. just get the eibach sway bar kit .. will really help you with the twisty roads .. check out www.dinan540.com (http://www.dinan540.com) .. great write up ..

I got mine for $800 at Tirerack.com. Reliable company that I have done buisness with before, so I had an account, plus they are close to me so I received the struts in record time.

Anything less than $800 is probably a good deal.

$638 is a ridiculously good deal if it includes the springs. Otherwise still pretty decent!

...if you can get the whole kit for that price them I'm on it!

That sounds right. They are selling at 40% off of list price at www.koni-usa.com.

I'm not getting the struts and springs though - I already have H&R. I don't want Eibachs. So... I'm looking at just the FSD kit - 40% off of list makes it ~$640.

I installed FSD's on my car a few months back, and I have to say, at the beginning it was kind of confusing in feel. It felt soft and isolated the road roughness abit more than the stock sports - I think less communicative of the road surface to the driver. Then you think it will be soft all the way because of the feeling..and you take a turn...and you realize that there is almost no bodyroll and the front bites really nice and the car is really light on its feet.

Taking turns and getting on the gas now squeels both tires, or bigger chirp from the rubber because of the bigger contact patch that I have (less roll). Before it would be just the rear inner wheel chirping as it gets unloaded in the turn. I dont think you can tell too much of a difference if you drive it till you get agressive. They are certainly more comfortable AND gives the car a nimbler lighter feel. Freeway agressive manuvering is still a bit squishy in feel, but I know its way improved from stock - could be also my Toyo F4s which are not as agressive as other tires out there.

FSD's basically take you a notch up in everything, and smoother too! I have M5 f/r sways so dunno how it would do without them. Also I found running with higher tire pressure made the car much nicer while in the stock setup, it would cause more uncomfortable mild vibration. When you hit potholes or rough roads....you want to be in an FSD car for sure. The sport shocks are actually pretty good for best of both worlds, and comparing it to FSD is not quite comparing apples to apples...as the FSD's are variable damping. The swaybars are the weakest weakest link and make THE biggest difference, especially the front.

I do have my sport shocks that have 31kmiles on them for sale and I believe they are in good condition before they came off the car. They are laying in my garage and I'm willing to take any reasonable offer. Also have a stock 540i muffler with only 5kmiles on it which I need to get rid of also. Just PM me.

I started a long FSD thread a few months back (3 or 4) and I invited an Engr from Koni to comment. He said, posted, if you want max handling go Koni sports but if you want good combo of ride and handling go FSDs.

Personally I think the Bilsteins are better than the Koni sports because the Koni's are very soft in compression.

I've had both on my 540 and I judge the Bilsteins to be best over the Koni sport for handling.

If I was looking for good ride quality I would go FSD.

GTMAN
09-28-2007, 03:09 PM
Yeah, from what I have read and spoken to tuners on, consensus say that if tracking the car and max handling performance turns you on, then Bilsteins is the way to go (with right springs of course). FSD's are for drivers like me that want a something like stock but a few notches higher. Koni Yellows are in between. When people ride in my car, when I drive "normal":), they think its a cushy luxo car and thats how the car came from the factory.

Never tracked my car, but once I rode in a professional instructors 540i6MT with dinan springs and koni yellows, and the way they guy threw the car around the track with 4 people along for the ride....it was mindblowing what the e39 is capable of in handling - that was car and driver skill right there. It was so well balanced and controlled.

I have not been in the e39 game very long and don't know. I don't think its THAT different in terms of the rear shocks, but the cars are so rare and its such a small market, that I think a lot of aftermarket folks just pass on the touring . . .

It sounds like the Touring would be IDEAL for the application of FSD, though. Would be silly for Koni to pass on it.

On the other hand, KW offers a couple of nice full-out Touring coilover kits. So go figure.

FSDs will neither raise the car not lower it. Same with Koni Sports and OEM shocks. Its only Bilsteins that will raise the car about 3/8 to 5/8", depending.

Mine has a different stance after putting the FSDs on. That was the only mod. It is not likely the actual struts, tho that could be possible. I actually figure the spring perches are slightly different, since I used my factory spings.

Car was lowered in front, raised in the rear.

There is nothing functional about the FSD technology that should raise or lower the car .... is probably what I should have said.

On the other hand, Bilstein's technology, which uses an internal gas pressure (nitrogen), does affect the ride ht.

Its possible the construction details and dimensions, internally or externally, may be affecting the FSD positioning/ride ht. An example of external would be the spring perch being positioned higher or lower than the OEM perch.

"Perch" always reminds of the good eating perch fish we used to catch by the hundreds (hook and line) in the Great Lakes.

Frank,
Do you know why the i6er's don't have problems with Bilsteins raising the ride height? My 528i has H&R sports paired with Bilstein HD's and I'm lower than any other E39 that I've seen in person.

Is bilstein, or maybe even KONI in this case, using wrong measurements for their v8 E39 applications?

There are so many variables with different models and years and what one mfgr is doing internally vs another it is impossible to say. Even when you call the mfgrs different ppl get diff answers from the same company.

Then the distributors all have their own ideas on top of that. Sorry I can't help.

I'm a fan of Bilstein and have poor words to say about Koni Sports, yet I've been thinking of maybe going to the FSDs myself.

That's not an economical thing for me to do since I've had the other two already on the same car.

I wouldn't state it that way.

The new technology in the FSDs intrigues me. I've had everything else so if I got a set I would have experience with them all.

If I can soften the ride a bit and still maintain a level of performance then its something to think about. Just think about so far.

For a street performance ride I think the Bilsteins are great, better than the Koni Sports. I'm not sure where the FSDs fit in, though I would go that way if I had to make a choice now w/o my experience of the others.

I'll wait and see what Black S has to say about them. I'm not in a rush to throw more $$$ at my car, other than some M5 bumpers front and rear.

As far as I can tell, (in relation to the ride height issue) the aftermarket manufacturers think we want even ride height at the four corners, and they base their "even height" calculation off of: wheel center to top of fender arch.

In that respect, the gap is even all the way around my car now, whereas before (with stock sport suspension) the back looked lower. I like to see the rocker panel even with the ground, or maybe slightly raked, but I don't like the raked look that much.

I considered coilovers, but that would have be 2x FSD$. I am considering different springs front and rear now... but I will probably just get some Intrax springs.

The FSDs definately are worth the $$$, even considering the weird ride height issue. I wish I had gotten in on that group buy! '

Black S, could you measure the height from the lower mount point to the top surface of the spring perch for front and rear? I still have my old struts around somewhere, and I am curious if the perch height is different; especially in the rear.

Who knows, maybe they designed these things for non-sport cars... :shifty

I plan to compare my sport struts with the Koni's. I'll take as many measurements as I can and post them for you guys (including before/after ride heights).

I'll give a good report after a late night run down my favorite backroad.

Understeer begone!!!!

OK, I couldn't take it. I got home about 45 mins ago and immediately jacked my car up and put my new M5 sway bar on. OMG!!!!!! I just got back from driving it. It really does feel like a different car Brandon - go do it!

For the record, understeer is GREATLY reduced. What an awesome mod for $130. Can't wait for the FSDs now.

M5 sway bar in!!!!!!!!
Punny sway bar out!!!!!!!!


I consider my H&R sport springs and bilstein shocks/struts to be my favorite mods so far. They transformed the way my car rides, sits, and handles, but with installation they cost nearly 1500.

I picked up this M5 rear sway bar with bushings for only 50 bucks. It's taken my suspension to the next level. It's sorta hard to understand how this little bar changes the car soooooo much. I love it! It's my new favorite mod!

I have more grip while cornering. The built in understeer has been reduced drastically. Confidence going into corners has increased. The car seems a lot flatter all around...

Driving my car just got a little more fun!

Glad you like it. Doesn't the car feel more responsive when you whip the wheel from one side to the other. It just stays flat and planted. Mucho nicer.

The rear is much more responsive. It just seems to rotate a lot quicker now.

I agree with Frank's, comment, I just want to throw the car into turns now. It's great!!!!

Now you are hooked.

Just think about how much better that next mod would do to the performance.

Tell us more about how it feels to you after a couple days.

Next mod is tires. Fk452's.
I want wider....

Max tire size on 17x8 Style 5's???


I'll keep everyone posted on my feelings about the swaybar. At this point I'm thinking everyone with an E39 should have one :D

Max on 8" wheels is 255s.

I would street away from FK452s myself. But lots of ppl like them. The sidewalls are too soft in my opinion.

They have good dry and wet grip, surprisingly so. I had a set.

What size 17" tires came on the car? I need to know to get the tire OD.

10-04-2007, 05:08 PM
I'm going to give the FK's a shot....I'd like to retain a small amount of ride comfort while still having a sticky tire...


My car came with 235/45/17's.

255/35/17???

franka
10-04-2007, 05:13 PM
No one makes 255/35-17

You would have to go 255/40/17. Original dia is 25.3 and these are 25.0.

That would work. Its better to go a little smaller than larger.

franka
10-04-2007, 05:17 PM
Tirerack shows lots of 255/40-17s brands and styles.

You can try www.edgeracing.com and see if the FKs come in that size. Edge should be the best on price.

Thanks, Frank!!

I'll be buying tires in a bit...

First tho is to have my gold wheel bolts shipped from Germany :D

The guys at the TireRack can give you a definite answer, but typically 245/45R17 is the largest tire for a 17x8 wheel that has the same overall size as OEM tires. You can go to 1010tires.com to try it out with various sizes.

Frank has given me pretty much the info I wanted...I'll do my research from here, but 255's are sounding saaaaaaaaaaaaaweet!

I don't mind the hijack guys - you have my permission. I've already decided on the FSDs and purchased them - waiting on shipment from Koni in KY.

I'm out of town until next Friday. So, the weekend following next will probably be my Koni install, rear brakes, etc.

After that, it's off to the tire shop to mount my Falkens and then over to get another alignment.
