Frequency Selective Damping: http://www.koni-na.com/fsd/index2.html explains it all. I'd hope there is actually a performance advantage/benefit in such a shock, given that they're OEM equipment on Lamborghini Gallardos. Anyone hear about this? Pros/cons? Opinions?

I haven't heard of the new Koni's.
It's a company that I tust to make a quality product, but other that that...?

As for the Gallardos... Let's just say it's not my favorite Lambo ever...

 

Here's some correspondence a friend of mine had with them re: the FSDs. What do you guys make of it?

My friend: "I have a few quick questions about your new FSD product. Why do you specifically state that if using the FSD shock/strut that one needs to remain on stock springs/ride height...? Is this special note on staying stock height FSD specific or do you apply this to all of your shock/struts products...?? I am looking at dropping the vehicle by about 1.2". Would you please tell me WHY is it that you do not recommend dropping the vehicle with the FSD... and what about the FSD makes it special (lets say compared to the "Koni Yellows") that it needs to stay on stock height... will the FSD product not function properly if the car is dropped by 1.2" or so? I dont get why i can drop the car with Koni Yellows for example, but not drop it with the FSD... Please explain this to me."

Koni: "You cannot lower the beyond about 25mm or make it near the bump rubber with FSD. The reason being is that if you do lower the car and place it near the bump rubber FSD will continuously see high frequencies. At high frequencies the damping forces are reduced greatly, because at a stock height high frequency only occurs with rough pavement or tire noise and such. This would mean that a car lowered more than about an inch(as a guideline only it could be less with some vehicles) the shocks will make almost no force at all and make the car miserable to drive. If you are looking for performance, FSD at stock height will perform about the same or better than lowering springs with the sports, without the harshness that occurs when a car is lowered.

Intereting...

I think I'll stick with my Koni Reds for now...

I can see the appeal of those on a daily driver/beater (Our Protoge for instance)...


BTW, your friend repeats himself a LOT... lol...

 

Yea I thought it was interesting too. Short of an electronically adjustable suspension and ride height, I don't think you can ever have the best of both worlds. You gotta sacrifice one for the other. And being that I have an R2, I think it's clear I'll sacrifice ride quality for performance, hands down. But an interesting concept/product nonetheless.

Yea you have no idea. I actually edited out a LOT of his initial message, as it was about double that length
