Eibach/Koni vs. Bilstein PSS10 for a street setup

[Obioban]

I am currently running Koni and H&R. The ride isn't bad at all, but they didn't last for long. Granted frequent 400+ mile round trips from PA to MA didn't really help them out. I probably have around 30k on the setup right now, but they were very hard miles.

The H&R springs don’t work well with any shocks.

If you want to significantly lower the car (1”), the PSS10s are not a good option. They work well at/near stock ride height.

I’ve had konis paired stock springs, bilstein HD paired with stock springs, and currently on PSS10 (with camber plates).
The konis were good, the fronts have a good range of adjustment and it matches well to conditions you would encounter. But I feel the rears were not so well matched to the car, too firm / harsh, and of course difficult to adjust. Overall a good upgrade from stock, but a little unrefined at times.
The PSS10 are a very good street to track setup, the adjustment range is very wide, with noticeable steps between each 10 clicks. A little firm at the soft end but more composed than the konis. Build quality is top notch, very substantial. As long as you don’t lower too much, there is enough stroke to keep off the bump stops. And they have the advantage of using the stock top hats, if you don’t need the adjustment of camber plates.
I don’t mean to be ‘phishing’ here, but I will be putting my konis and PSS10s up for sale shortly.

Agreed— which is why I’m running TCK Koni SAs on the rear (on the M3 wagon), with generic Koni yellows up front. Softer and top adjustable (instead of compress to adjust).

I would recommend getting Ohlins, I have them on my 335i and just got Koni Yellow/Eibach on my E46 M3. It's a good setup but I keep imagining how the Ohlins would be on the E46.

I remember back on M3F someone went way down the rabbit hole on suspension, and his conclusion on most comfortable ride that didn't compromise handling was Koni Yellows paired with Dinan springs. After that, he went into custom valved Bilsteins from FatCat Motorsports to improve. KY/Dinan is where I plan to take my own car for the same reasoning you stated.

I'd go bilstein over koni for OTS solutions anytime. I made my own coilovers out of Bilstein B6 & eibach springs (ground control hardware). Wayyyyy better than any of my Koni & eibach or H&R combos.

Only Koni's I'd get are TCK D/As. If it's a DD, not as important and I'd even recommend Koni over Billy for the rough roads and lower speeds of a DD in the city.

I'm currently on stock ZCP suspension, but am looking to lower the car a bit (~1") without degrading the handling or ride quality too much. I recall the Eibach/Koni Yellows combo being popular on M3F, but haven't seen it discussed much over here. I like having the adjustability of coilovers and I've heard that the Bilsteins are reasonably comfortable on the street given the progressive spring rates. For reference, I have the Ohlins R&T on my E92 M3 and am looking for something more comfortable than that. Has anyone tried both setups and can comment on the pros and cons of each setup for a street car (aside from price)?
