Thanks for the comments. The FSD are a great setup but only the Koni Sports (Yellow) are available for the E46 M3. I know they make FSDs for the non-M E46 cars.

If I was truly going to track the M3 all the time, a different suspension setup would be required. But for street, since I am using still BMW M3's stock OEM springs, the KONIs were more than appropiate. If I decided to use lowering springs for looks, I could still keep the KONIs and just crank up the rebound about 1/2 turn at all 4 corners.

Good luck with your KONI install in your Prelude.

Interesting that you quoted Lee. He's a frequent poster on honda-tech.

A note about Koni's to anyone who tracks their car though: Imo, they're pretty decent street shocks but I would not pick these for a car that sees track time, just because they are twin-tube. Looking at dyno's of various Koni's, the low speed damping (not dampening ) is not as strong as monotube design dampers from makers such as Bilstein/Ohlins/etc. Apart from that the monotube design is much superior in handling the heat that the dampers develop in track situations.

The shocks I had on my car previous to this were Bilstein Sport's. Those were in only for a month because the ride was just so ridiculously harsh. The front rebound valving produced in excess of 5500N which is appropriate for 850-900lbft springs (race car spring rates). They must have been designed during Oktoberfest.

Having said all that, Koni Yellow/Sport's are by FAR the most popular shocks in the Honda world.

Btw, Koni has a new technology out which is really fantastic. It's called FSD and lowers the compromise between low and high speed damping giving a really nice and digressive curve. I believe Lambo is using it as OE in their cars and Koni is now starting release aftermarket products featuring it.
