Eibach/Koni vs. Bilstein PSS10 for a street setup

[SP-1]

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



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).

Thanks for the replies. How would the PSS10s compare to Eibach/Koni overall if they were set at roughly the same height?

Well that is very interesting. Because they use H&R in their higher line PSS9/PSS10 kits.

With ride height adjusters

The Dinan Koni yellows are unmodified Koni yellows. They just pre set them to
Front = 1/4 turn from full soft
Rear = 1-3/8 turn from full soft

Since they're ~double the price you can get them for otherwise, as it takes ~30 seconds to put them at that setting, I don't think it's worth paying the extra.

Awesome... however, having only studied the metric system, how would you put 3/8's in terms of a percentage?

Where would you say is the cheapest you can find Koni Yellows?

Also, seeing as I was about to do a whole suspensions refresh, what other hardware (shock mounts, bump stops, shock mount plates, dust covers etc) would be best suited to running the Koni Yellow/Dinan spring combo?

3/8 = 0.375 -> 37.5%

Or 135°

Or 3/4 pi radians

[Obioban]

Yep.

I think Koni talking about turns in eights because their knob has 8 indicators on it-- so 3/8 means turn it 3 koni knob indicators.

Interesting. I'm currently at 1/4F and 3/4R. I was about to adjust the fronts to 1/2 or 3/4 and bump the rears as well. Perhaps I'll try the Dinan settings instead and see how I like them. I can't imagine going higher than 1.5R as the comfort level over stock is just too good to give up.

Oh my that's a good eye! I have been using Koni's for decades and never bothered to count the edges and never would have put that together.
I just remember Gustave in my E30 M3 days measuring the changes of turning the knob and finding out it was not a linear increment change. So half way dial turned between Soft and Firm was Not half firm setting nor half soft setting.

Perhaps, but you've stated 1/4 for the fronts, which would translate to 2 clicks I guess, and 1-3/8 for the rears, which I assume is 1 & 3/8's... how can that be Koni speak?

Such a variety of opinions on this one & different to my experiences. (...its all about the shocks, not the coils, tried fresh OE Sachs, then hated the Koni, then found the PSS10 totally superb)
So its PSS10, but they need corrosion protection at installation, especially greasing up the rear damping adjusters. Photo of mine after 3 winters.

1-3/8 or 11/8 or 11 notches. It’s just fractions...

The coating is the weak link on these. They don’t even hold up to rain without losing their luster.

Koni rebound adjuster has no clicks.

😱 Wow I cant imagine what your undercarriage must look like. Looks like your suspension was parked in a brine pool. Threads look like they held up ok.
My PSS9s look almost new after 7 plus years. But I live at the beach.

You sure those aren't parts of the titanic? Wonder why they can just powder coat them or something.
Agree though, it's all about the shocks.
