Koni FSD dampers, Eibach Pro Springs, and Eibach rear alignment kit were all purchased from Tirerack. Additional suspension/stability mods on the car are stiffened rear motor mount and adjustable rear anti-roll bar. I was not concerned about lowering height, but the very mild drop is pleasant and subtle. The suspension now exceeds the limits of the tires on the car by a wide margin (Conti DWS). The ride is now quite firm and the rear is now more active (attributed to sway bar mostly). The rear alignment was set back to stock settings. This was purchased as a replacement for stock suspension with 80K+ miles on it. Handling is much improved, but for me it is a significant trade-off vs. ride comfort. Do not expect the comfort of a VW GTI with this setup. Torque steer is very mild since the motor is an aggressively-tuned stock turbo plus bolt-ons. I would recommend this as a performance upgrade to replace the stock suspension if ride comfort sacrifice is required to a lesser extent. Most importantly, it is still an acceptable daily driver for me. It is more comfortable than a 2006 Porsche Cayman S, for instance. -- Review submitted: 2013-07-28

The Koni FSDs certainly did not transform my car s ride. However, I do think it is a little smoother on the highway (high frequency damping) and handling is still at least as good as my stock sport dampers. -- Review submitted: 2013-04-23

Ride is pretty firm, but handling is much improved. Damping is very good. Feels like a factory performance suspension according to my alignment guy. Almost eliminated torque steer. They made the car a lot more fun to drive. Now I want the thicker roll bars... -- Review submitted: 2012-07-03

Overall, I am very pleased with this spring/damper combination. There was a hiccup in the process due to Tire Rack not making it clear that the ride height would be increased (beyond acceptable) with installation of the FSDs only. That necessitated a second trip to the installer for the spring installation. Which, including the stabilizer bar links (which are a must after having to essentially destroy the originals to remove them), added $541 dollars to the scenario. Tire Rack did help out with free shipping of the springs, but the site should be totally clear about the ride height issue. The spring/damper combo is excellent. The change from stockers to the FSDs was definitely an improvement, but the springs were the major improvement. The combo is excellent and handling the 60-90mph pavement "whoop-de-dos"...which had become quite an issue. The FSDs do exactly as they are advertised, and I am very happy with them. Again, this is definitely a combo install. Which, with install costs, becomes a fairly pricey proposition. But worth it. -- Review submitted: 2012-06-29

My objective was to achieve a more comfortable ride quality while maintaining or increasing handling in my 2009 BMW 128i with sport package. I first installed a BMW aluminum strut brace and noticed an incremental enhancement in cornering dynamics. After extensive research, I decided to install Koni FSD dampers along with Eibach anti-roll bars while keeping the BMW sport package springs since Koni recommends stock springs with it s FSD dampers. After installing the Koni/Eibach set up (12 hrs), the BMW technician commented that the car was extremely smooth on the highway, and in his opinion had more responsive steering along with no body lean while making a quick lane change. He does track his 3 series by the way so his opinion does carry some weight. In fact, he said the suspension was such that the tire s traction would give out long before the suspension ever would in the event of extreme handling maneuvers. I was of course eager to drive the car and must confess that my initial impressions are limited to a test drive which included backing up and departing the dealership, a 3 mile average condition curvy road, (5) 90 right hand turns, and a quick passing maneuver around a slow driving retiree before I had to park the car and leave on a business trip. My initial impressions are: 1. The car s steering is more balanced and responsive and the steering wheel is slightly easier to turn in parking lots. 2. The overall ride quality is smoother and more comfortable on smooth surfaces as well as bumps with less vibration in the steering wheel. 2. Handling on turns has been significantly improved with respect to body lean. I was quite satisfied with the above improvements and my car felt more "connected" and engaging in my driving experience than did the 2012 BMW 3 series that I had as a loaner. My car feels more "buttoned down." -- Review submitted: 2012-05-25

Driving over railroad tracks and the odd pothole (when it can t be avoided) is less jarring than running with stock shocks & struts. On the freeway, road noise is minimized. The FSDs really tighten up with faster turn in on corners. Running faster sweepers, the car feels more planted than before. Overall, a very good choice. -- Review submitted: 2012-05-21

OMG this is what the car was meant to be...What a terrific present to myself for hanging in there with the suspension the way it was for 10yrs...I also had no swaybar in the back originally. All I can say is that it is really smooth..roll is almost non-existent...ride is firm but not harsh ..these products & Tirerack have exceeded my expectations -- Review submitted: 2012-04-25

*Initial review* (After a few weeks and 200 miles of use)

First my background, couple of years with SAE Formula and SAE Mini baja, and some autocrossing and drifting. Most of my cars have adjustable suspension, and my mountain bikes have adjustable high/low speed compression, rebound adjustment, and adjustable spring rates. So I only have basic suspension knowledge :D

Okay now about these dampers, you have to read the Tirerack s test very closely and be sure these perform well in the category that is important to you. Remember the FSD do automatically adjust but it s ONLY on the rebound/jounce, the compression rate does NOT change, so that can be good and bad. So this means that it will eliminate body roll with SLOW to MODERATE steering inputs (eg. lane changes and cornering on ramps). And they will work AMAZINGLY well at eliminating small FAST bumps (eg. tar strips, expansion joints and small bumps at HIGHWAY SPEEDS). Since these dampers abosorb fast suspension movements, these will NOT work that well when you quickly turn the wheel back and fourth (eg. trying to dodge road debris). And if you hit a BIG dip or bump in the road, the car will drop very low use up all of the travel and rebound kinda quick. My car ( 03 BMW 330i Performance Package) also had a slight drop in ride height after the FSD were installed, maybe 1/4" front and 1/8" rear.

So in conclusion, most of the time it corners well, and I guarantee it will make the car more comfortable on the highway, but it will feel under damped if you hit anything big that uses alot of travel. -- Review submitted: 2011-09-01

I have a 325Ci with the sport package. While the car rides extremely smooth on an even surface ( almost like a MB ) it tends to fall apart ( like a Lincoln Town car ) on rough pavement. Some much so that it feels like the wheel is pattering over rough bumps when the suspension unloads.



If all I did was freeway driving then these are plus. However I have miles of back roads in my commute and I m disappointed on those roads. I should have gone with the other Konis or Bilstein HDs. -- Review submitted: 2011-08-09

The FSD damper set is a very good investment. I like cornering fast without having a harsh ride. My 330ci comes with the factory sport package which lowers the car for about 1". Since itís a 10yrs old and OE dampers have reached the limit, I decided to shop for a new set of damper. My goal was to maintain or slightly improve the handling without losing any comfort. I was also trying to keep my budget below 1k including labor cost. I am glad that I picked up the Koni FSD after a few days of research. Austin TX doesnít have the best roads in the US and these dampers provide a fun ride on those twisty mountain roads as well as a comfortable commuting drive. -- Review submitted: 2011-07-08

After reading such glowing reviews I purchased the FSD dampers two years ago. My primary goal was to reduce the harshness on the highway felt when driving on rapidly undulating concrete. Highway surfaces here in Los Angeles are unlike what I am used to in Baltimore and Rochester NY. They really subject the suspension to a high-frequency pummeling. I-405 near LAX is really unpleasant.



Installation of the FSD s did nothing to improve this situation. I also feel the improvement in handling harsh expansion joints, like a 1 inch step in the concrete, is very minimal. These still hit you very hard but I feel like the recovery from them is a bit faster. The only improvement, which is quite remarkable actually, is when driving over badly deteriorated asphalt. Here the FSD s perform as expected and soften up enough to practically erase the bumps completely.



It seems the undulating concrete highway is not quite harsh enough to trigger the high-frequency component of the damper. Expansion joints are harsher, more abrupt disruptions and do seem to trigger the high-frequency component, however by the time the valve has opened up, the expansion joint is already passed. They just don t seem to activate quickly enough to really help. But hitting a longer stretch of broken pavement, they work much better. The initial bump is harsh but the rest is like butter.



Another issue is for very severe potholes (missing chunk of asphalt 5 inches deep) the FSD s soften too much and will use all of their available travel and hit the bump stops more frequently than with the stock dampers.



Overall, I would not buy these again. Body roll is no worse than with stock dampers however.



My car is stock with 17" wheels and BFGoodwrench g-Force Sport tires 205/50R17. I think a softer sidewall and/or 16" wheels would do more to improve driving comfort. -- Review submitted: 2011-05-24

This is an excellent damper set, far superior to OEM. It performs as described except the softening of small sharp-edged surface features is not spectacular but noticeably. Otherwise I am very happy with the compliant, crisp response. In sharp winding turns the car remain flat with natural-feeling control. Sudden dips are taken in stride. A winner at the reduced price. -- Review submitted: 2011-03-16

I was somewhat disappointed initially in the increased ride height. However the ride is much less punishing compared to the oem Sport Suspension Plus dampening. Where the SS+ would often bounce and skip out over rough pavement, the FSDs keep the SSR wheels planted; very sure footed cornering on real world pavement. I run 205/55-16s and with SS+ the rear tires would rub the wheel wells in dips. It never has happened since I put the FSDs on. Turn in feels every bit as crisp as before, and yet it has made motoring much more pleasant, particularly on trips. I am very satisfied. -- Review submitted: 2010-01-17

The upgrade over the OEM (stock) suspension is greatly appreciated. The car drove pretty well before, but the driving experience is far better now. The slightly lower and higher-rate springs do a great job of reducing roll, dive, and squat, which means a maximized contact patch with the road. The real magic, however, is with the FSD dampers.



The Koni FSDs are perhaps the best compromise between performance and every-day comfort. They reduce/eliminate rebound and keep the tires glued to the road nearly as well as Koni Yellows on the firmer settings, yet soak up the small, high-frequency bumps enough that the ride is very comfortable for every-day commuting.



Anyone who is looking for the best performance "street" dampeners on the market should look no further than the FSDs. I cannot recommend them enough. -- Review submitted: 2009-07-31

This is the first set of new dampers I have installed on this car, I think I can remember the originals as not being as compliant on jounce impacts as the FSD units. Though pricey these are the best dampers I have ever had on a BMW.

They handle mid-turn surface variations and bumps very well. I like um! -- Review submitted: 2009-06-09

First I should say that the stock Mazdaspeed3 dampers are junkso almost anything is an improvement.



These dampers literally transformed the handling, traction, and greatly increased the overall road speed I''m able to carry with a good safety margin - all at very little cost to ride comfort.

The FSD''s work as advertised, for the most part. All aspects of handling were greatly improved with minimal to zero impact on ride comfort. Not perfect but far better than stock.



Great dampers for sporting drivers who do occasional (or zero) track days, but mostly enjoy a quick, safe, well planted car in the back country, without smashing over every minor bump in the road. -- Review submitted: 2009-05-20

The Mazdaspeed3 comes from the factory with poor dampers. The FSD''s even though they''re valved for the standard 3 spring rates have substantially more rebound damping on low frequency surfaces yet loosen up a bit on high frequency surfaces (choppy road vs. undulating), which keeps the tires planted. It also helps with ride comfort and general stability, especially under braking. Huge improvement over OEM parts, valving is close enough for the speed3''s higher spring rates, but I wouldn''t use them with even stiffer springs.



In any event, the car simply does everything better now. The stock car had extreme issues with excessive body motion over bumps and undulating pavement that made it scary to drive quickly. The rears in particular are quite bad, I almost lost it when they caught air and sent me into snap oversteer.



Now I can go safely travel over the same roads at much higher speeds. The car is more predictable on any kind of surface, especially bumpy ones, and the ride comfort is excellent for a performance damper. The ride -quality- is vastly improved, it drives like a much more expensive and better sorted car now.



I would love to see an adjustable version of these dampers in the future so that a wider variety of springs can be used. A Koni tech told me that they''re designed for stock springs and "factory lowered" springs, like the speed3 and other factory tuner cars. They self adjust to a certain extent but it would be nice to fine tune that to better match aftermarket springs.



3 install issues: 1) they use too much paint where they mount into the steering knuckle. Grind it off before installing and lube with anti-sieze. 2) the rear damper bushing is a little too narrow for the mount. Use washers to compensate. 3) the front was initially lifted nearly half an inch but it''s settled down to about half that.



All worth it though. Unless you''re going for lap records, these are excellent dampers for enthusiast drivers who also like a civilized ride. -- Review submitted: 2009-03-18

I installed Koni FSD shocks and struts along with Eibach lowering springs on my 2001 Audi TT 225 Roadster. This is an outstanding combo for this car. The ride is firm and controlled, but not harsh, and car was lowered exactly 3/4 inch all around--as specified. The FSDs really tamed the jittery ride that was experienced on the stock dampers. If they made FSDs that fit my S4 I''d install them on that car also. -- Review submitted: 2009-02-22

I wrote my concerns about impact harshness at 1,500 miles post-installation. After changing to tires with softer sidewalls (from F1 GS D3 to Pilot Exalto PE2 summer front and Avan S4 rear) the harshness was eliminated and I''m very satisfied with the overall handling and ride comfort. Perhaps addtional miles on the shocks helped, but the softer tires certainly made a big difference. -- Review submitted: 2008-08-09

Koni FSD damper set does provide acceptable handling with a good city ride. But, don t expect these to be sport shocks and struts, as they are too soft and don t control the body motions of the car well enough. Again, they are fine around town, but even at 80mph on the highway, they do not have the rebound stiffness to taughtly control body motions over frost heaves or compression dips in the highway, and they don t like fast steering inputs (especially transitions).



Overall, they are a comfortable shock that handle OK, but if you are looking for a "sporty" shock, these may not have the control you re looking for. -- Review submitted: 2008-02-11

Before installing the kit, on exit/entrance ramps, I could push pretty hard, but once the SP9000s lost grip (in the front always), the car would plow (understeer) until significant speed had been shaved, allowing the fronts to hook up again. Now, with the kit installed, not only is the ride more comfortable in every aspect, but my Passat now corners flat; when there s traction loss (at now much higher speeds), it feels like every tire loses grip equally (at least front to back), and i can play on the limit of my traction. Push a little much - slide a little - perfectly sideways - take a smidge off the gas and keep the wheel pointed where you want to go - and BAM - you re there. This suspension kit really inspires confidence.

The best way i can describe the difference in ride is this. The old suspension was soft - always. You turned - it leaned appropriately - like a normal car. With the FSD Pro-kit, the harder you turn, the harder it holds the car. It feels much more natural - like the way you would react if you were a car - while steadily cruising you re relaxed and silky smooth, but if you get pushed - you instinctively push back.

The only gripe I can muster is that the kit could be available for more vehicles.

P.S.

my car is also equipped with a 5spd manual, Dunlop SP9000s, no leather, no sunroof, and i have yet to drive any car costing twice as much that I would ever consider as a replacement for my Passat. This kit is that good. -- Review submitted: 2007-12-13

Around town these Koni FSD dampers are more compliant than the factory shocks, which makes for a much more comfortable ride. My wife and kids don t mind riding in the M5 anymore. At about 80 mph (and up) on the highway they are really in their element. Over large undulations, such as overpasses and segmented concrete sections, the FSDs feel firmer and reduce the body motions quite well without being harsh. At the same time, small surface irregularities and expansion joints that seemed to transmit directly to the cabin with the factory shocks are almost unnoticeable now. I took the car to the track and was somewhat dissappointed that these good street manners did not translate better to the track environment. They felt slightly too soft in compression overall and way too soft in rebound to adequately control body motions while negotiating fast right-left corner combinations, particularly those corners where the suspension did not have time to "load-up" laterally. Large corners on track, such as large sweepers and one large banked corner, did not upset them and they did quite well in these situations. I think this is where lots more rebound control would have helped with such a heavy car. With the factory springs and the FSDs the front of the car sits about the same height as with the factory shocks, however, the rear of the car now sits about 3/4 of an inch higher than with the stock units. I hope this is something that will correct itself after a little "break-in" time, but it really looks odd with the back "jacked-up" like it is now. I guess for the 95% of the time I spend in the car for city/highway driving these FSDs will be fine, but I have already started saving for those PSS9 coil-over units. -- Review submitted: 2007-12-08

Koni FSD perform as advertized - firmer compression stroke, softer rebound with reduced understeer. The compression performance is too harsh for my preferences however - especially in the rear. At slow speeds, road irregularities are better absorbed than with OEM shocks so that was an improvement, but expansion joints taken at high speeds jar the chassis in a way never experienced with this car, so that was a negative. I probably should have purchased Bilstein HD shocks instead. -- Review submitted: 2007-07-20

We ve installed four sets of FSDs on MINIs and have had issues with two of them. On my personal car the shaft seal on a rear strut began leaking after 6200 miles of use and has been returned to you under warranty. A brake line bracket on another club member s RF strut was welded to the housing at an incorrect angle -- a dye grinder fixed that. Koni has done well with the engineering of the FSDs, but the quality is lacking -- they are still not Bilstein. -- Review submitted: 2007-04-24

Salesperson was right, the FSD set is a "no lose" proposition. Like them so much I purchased them also for a VW Passat W8, like them even better on the Passat. They may cause a very slight increase in ride height. -- Review submitted: 2007-04-17

First I put the Eibach pro kit on, and the ride was smoother than stock, but when you turn in theres less sway than with the stock springs. I was happy with that for about a year, then I installed the Eibach anti-roll kit. That made a big difference in cornering speed, I have this off ramp that I take sometimes at high speed, 110+ its on rails. Then I installed Koni FSD damper set, the first 3 or 4 weeks it was a little stiff until they broke-in. Now it rides better than ever, what can I say, my mazda3 is hooked-up! Thanks Tire Rack and Iam happy with your customer service, when I got my Konis, they where packaged wrong from the factory, and you resolved the problem, quick! Thanks again. -- Review submitted: 2007-02-20
