Thanks, your response is the paradigm that Koni is trying to overcome! At risk of sounding like paid advertisement (which unfortunately I am not) what if you could have increased handling and a better ride? Porsche obviously thinks there are buyers since they went to the expense to develop the PASM system using computers to control the dampers. However these may not be attractive to the used market buyer having to potentially spend large amounts to maintain these systems. The FSD is able to make internal adjustments based on the frequency of the event, And makes this technology available for our generation cars. Do you give up race car handling? The Vodafone McLaren F1 racing team apparently didn't think so as indicated in the attached. And if it was good for the McLaren F1 team I'd think it would be sufficient for me.

Thanks Steve! I've been paying attention and enjoy your posts! Just thought it'd be worthwhile to gather your perspective in this thread since there doesn't seem to be much experience with these shocks. Also want to say I do agree with you cause These shocks are Fantastic!

So this is very, very early days, but the car is back on its wheels, Koni FSD, stock springs, (I'm UK remember so maybe different to your US springs), top mounts, coffin arms, drop links, ARB bushes, Track rods, tuning forks and trailing arms. Its a bit good!

There is significantly less body roll than I expected, its very flat - that must be the slow speed compression damping - yet the bump/rough road performance so far feels excellent. and its so nice to have no rattles, bangs, knocks or anything at all! I did think I might need some stiffer ARB's but on first efforts I'm not sure I will.

Unfortunately I couldn't book in for an alignment until next week, so despite me doing best efforts to get it roughly straight with stringing out, it drives horrendous because all the wheels are pointing all over the shop. So ill have to wait before I really push it, but so far, so good - I think these Koni FSD could be exactly what a number of people want!

Bump, everyone still happy with their choices? Any more feedback?
My struts are done. Looking at the B12 kit, ROW M030 kit, FSD with stock springs, FSD with ROW M030 springs, Koni sport with ...

Strange I keep missing posts..... I agree with your assessment and would like to hear what your thoughts are after the alignment. I haven't found any fault with my FSDs during hard driving, corner entry is very flat and bumps mid corner are soaked up very well. I'm especially impressed with the way they soak up the seams in concrete paving, the slaps that felt like the steering column was bending are simply gone, amazing.

Hey Will; I saw your other post regarding frost heaves in Canada. Sounds like the FSDs would work very well for you on stock springs. Broken pavement would no longer be something to fear. I am in central Cali near the earthquake capital so we have similar roads, cracks and upheavals and I can say I am extremely happy with mine and would not hesitate to recommend them. Of course only you can determine what is best for the type of driving you do, but if you're not a dedicated track rat, but are simply looking for a more capable car for the occasional AX or DE, that rides much much better getting there, then look no further.

Thanks for your response. They are on the short list. I'm waiting to hear back from the dealer on the ROW spring prices. I would like to combine the fsd with ROW M030 springs for a small drop and rake adjustment.

Sorry duplicate disregard

Sits too high for my taste; looks like a 4X4

Been surfing the net and found this

Direct competition for the Bilstein b12 kit at a great price.

Any more feedback regarding FSD or Koni sport on row m030 springs? Getting ready to pull the trigger.

I am Koni FSD with USA M030, 2000 S manual, so not exactly the same, but I love it. Comfortable on the street, and handles well on the track.

That's the way I'm leaning. The dealer came back with spring part numbers that seem to relate to USA030 instead of the ROW030 I asked for so I'm holding off until that gets cleared up.
My thinking is that the ROW 030 will firm things up and give a slight drop and rake while avoiding the need for adjustable rear toe arms. The FSD should keep it livable on my crap roads that it gets DD duty on. Well that's what I'm hoping anyway.

The Koni sport kit is available in Europe for an attractive price but looks too low for me and will need adjustable rear toe arms. That puts it into RoW kit price.
RoW M030 springs for 5speed look to be unobtainium without going with the full kit. Full kit from my local dealer is 2350$cdn. Carnewal appears to be better priced.
Stock RoW m030 shouldn't be too bad right? How's dealing with carnewal?

Carnewal was good, Gert was good to deal with. It took a while for them (my Koni FSD order) to get here though, due to a wrong part being delivered to his shop or something. I don't have the exact amount of time, but maybe 6 weeks? Normally I think it would be more like 2 weeks. Email him and reach out, he always got back to me very quickly.

Thanks Steve,
I inquired about a mix and match with the FSDs and it added over 400€ to the price and a possible delay of several weeks for the FSDs. But it seems if he can order the springs he has better parts availability than what my dealer has so I may forgo the sways and just order the springs and FSDs. Be a shame to go this route when the whole Porsche kit is so reasonably priced and complete. I'm less sure of my direction now...
Looking more like Porsche kit and when those dampers go off...

Yesterday we installed a set of Koni FSD along with a H&R springs on my younger son older Jetta, drove the car for about two hours going back home and really liked the combination, great chassis control (firm) but without the harsh ride.

.

RoW M030 springs and FSDs ordered from Gert. 4-5 week wait for the FSDs so it will be a while before a review.

Did they arrive yet?

My FSD will be going on with -10 H&R springs. It's replacing my old M030. New arms all round not that long ago and will also have fresh drop links and Powerflex arb bushes and some Kmac adjustable top mounts.

No, Gert said it will be a few more weeks. They will be from the latest production run. Factory fresh so to speak.

My FSDs have been sitting in my garage since the turn of the year.

This is almost exactly what I want to do (though I have ROW M030 now). Do let us know how it goes and what additional parts you required.

I am in UK so already have what you call ROW M030 on my 550 Anniversary. I already have rear adjustable toe links. With the new parts I already posted and the arms/bushes already being done I am not expecting anything else to be needed.

I should be getting mine soon :):dance:

Anyone else having problems with this site?

Got them yesterday afternoon. Will try to find time to install this weekend.

Fronts are in. I'll save the review for when the backs compliment the front but so far after a ten mile blast :)

Update, finished rear install yesterday afternoon but battery was low from leaving trunk open all day with keys in... Battery charged over night.
Morning run for pastries, :) what a difference. I'll give the new springs a week to settle and get it aligned.
Initial impression is crashiness is gone and ride is firm. I think upgraded sways might be in the cards though.

I now have some time and miles on these and here are my thoughts.

The car now handles larger road imperfections that would make it feel as though the windshield might break with no more than a small thud if that. The smallest stuff is still noticeable, I assume because of the higher spring rate of the M030 springs. Cabin noise in the form of squeaks and groans is greatly reduced.
Generally very pleased with the ride and it corners flatter than I had imagined it would.

Rear fitment was not great with the paint being scraped off the bottom of the strut while getting it started. Also the weld blobs,(too big), on the bracket to casing fouled on the knuckle gap. I will have to touch up the paint. While getting the alignement I noticed a bit of dampness on one rear. I will have to keep an eye on it. And finally at -10C on my morning commute yesterday the ride was noticeably stiffer. Searching the net I found several comments regarding cold weather operation that were not favourable. While not a concern for the boxster, as it goes into hibernation soon, I had thought of getting a set of FSDs for my winter VW MKV. Plans now changed to Koni yellows that I should receive next week.

Have more time on these now.
The damp rear strut got much worse and was replaced.
I'm not convinced that these are a good match for the ROW M030 springs. May work better with other springs?
At -10C weather these struts feel like they are on full stiff.

I know different car and all but last fall I put Eibach ProKit springs and Koni yellows on the winter VW MK5 and love the combo. Very predictable and reasonable. Adjusted full soft they are both firmer and more comfortable than the Monroes my wife put on her VW mk6 sport wagon a few months prior.

If I were to do it all over again, this is the route I would go, and budget for the adjustable rear toe links and sways.

What are you comparing to? What was on the car before?

Stock setup. I'm thinking the Row M030 spring rate vs dampening rate is my issue. Big hits are taken care of very nicely but smaller imperfections not so much. They probably would work better with softer/more progressive springs is my thinking.

YMMV but at this time of year here, most of the roads have frost damage and haven't been repaired yet, same roads I been blasting with the VW running yellows and Eibach that takes it all in stride.

I've run standard S (58k), brand new M030, old M030 (105k) and new FSD/H&R. You do feel the edges more with different springs. I'm sure the ride will be more comfortable with a softer spring.

So what is your opinion on set up for a Euro Boxster S with the standard suspension, to flatten it out more in curves, but not stiffen it too much?

How would the FSD work with stock springs, and maybe a stiffer sway bar?

I haven't tried all combinations but if you want something firmer than standard with more damping control then the FSD works well. I think it has a greater range than an M030 damper. My FSD are paired with my M030 ARBs or sways as you call them and the M030 spec -10mm progressive H&R spring. This seems to work well for me and is at the right place on the performance Vs value spectrum.

Having previously tried new M030 I wanted to try something different. It's not that the M030 on my old car didn't work it's just that I'm curious and like to try something different. I haven't yet tried it on one of my week long Alps or Pyrenees trips but it handles and rides better than M030 for me.

I am curious but lack enough funds to experiment. I have a turbo ford mondeo titanum my wife complains constantly about the ride being to firm, I love so makes a dilema. I want to keep her happy but stiffen the car up, want to do a long road trip from Seville up to northern spain and back, so need to keep it tame.

Update.
The FSDs performed as advertised even if I’m not convinced that the ROW M030 spring rates are a good match. But having left the car outside in -10C all day before my commute back home, I have to emphasize that these are not good in the cold. If you don’t drive in those temperatures or colder, than you will likely be happy with these. For my money, when I do it again, I’ll be going with the sports.

What makes FSD to perform worse than other shocks, especially those typical non-adjustable?

You will pick Sports next time so you can adjust softer for winter (assuming you are not already softest for summer)?

I'm considering FSD now and I daily drive mine through Michigan winter so cold performance is a factor.

The compliance is greatly diminished. It turns into a teeth and car rattler. I assume it has to do with the crossover valving/viscosity. Worse than regular shocks and cold.
