I've been interested in FSD since Koni started talking about it.
Would you take these to the track? Ideally I like to track about 6 times a year. I also hit the twisty backroads pretty hard from time to time. I like more spring usually, and even go so far to upgrade sways on some cars.
You guys pretentiously diss people that "upgrade" their spring rate or even - gasp - install coilovers. But I wonder if you use the car at the track? Some people are happy to trade comfort and practicality for a performance edge at the track. <raises hand> Even if the "upgrade" is mostly mental and is only relatively marginal - it's just something fun to do that does provide a result.
Last time I checked however, Koni does not recommend these for use at the track, and will steer you to the koni sports. I'm not a big fan of adding stiffer shocks to soft OEM springs...talk about a hokey crappy ride, been there done that t-shirt is in my rag bin. Matched spring/shocks or coilovers works better. Koni sports off the shelf are seldom even within a reasonable percentage to match each other, and the twist to adjust feature does not apply the same amount of adjustment across the board. So unless you have a shock dynometer in your garage it's a crap shoot (ironically the same is true for click to adjust coilovers - like the cheap ones I have :lol If they matched better, koni sports would be great. But if I get those I will be taking them to a shop with a dynometer and we will experiment with the adjustment until they are matched up.
To get it right costs money. Ideally I'd want a custom valve matched set of penskes or bilsteins to the spring rates chosen for the car. Set it and forget it. The nice thing about the FSD's in theory was they work well off the shelf. But I guess a track environment is too harsh?
Anyway...I want the idea of FSD's but in a package that works with stiffer springs (ok and why not a little bit lower for cg improvement) and the track.

i decided to go with the FSDs on my mz3 over the yellows because of the miss matched possibilities of the adjustable yellows. i have mine paired with the eibach pro-kit, which is ok according to koni, and is a very nice street-able setup. i do autox my 3 often too, and the FSDs do well, reducing the dive and roll, while increasing overall grip and giving the car a bit more balance in the corners.
