Eibach/Koni vs. Bilstein PSS10 for a street setup

[old///MFanatic]

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.

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.

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.

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.

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

3/8 = 0.375 -> 37.5%

Or 135°

Or 3/4 pi radians

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?

[Obioban]

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

With ride height adjusters

[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?

[Tbonem3]

Wouldn't be surprising though; they sell their B6 packaged with Eibach pro kit as the b12 (they used to pair with H&R.)

[old///MFanatic]

I have the B6 with eibach springs, I like them just fine and enjoy it a lot on back roads, extremely composed when pushing it.
[BI also asked Bilstein about getting a different spring than the eibachs for the B6 shocks, they strongly advised against it [/B]for what it's worth.

You saying they strongly advised against using a different spring than what your Eibach specs were close to? Or about a different brand than Eibach?
Because it kinda reads like you’re saying they’re against other spring brands and Eibach their first choice.

[old///MFanatic]

Has anyone used the Dinan Springs and newer Koni SA shocks? Those seem that they would play well together.

For a (non adjustable height) set-up for a street car this should be one of the better combos.

What would be a good starting point, adjustment wise, for front stock Konis, rear TC Kline Konis and stock springs? The car is be used almost exclusively for street use.

[Obioban]

Would it be beneficial to go with the pre-adjusted Konis from Dinan?

Great post Obioban - thanks. I'll have to investigate travel more thoroughly on my MCS 1WNRs - I just naively set ride height to 13.5F 13R with spring rates chosen using Shaik's calculator and then corner balanced from there, but I should see what the implications of that ride height mean for shock travel.

My daily M3 has some beat twintube Bilstein B4s and Eibach springs - sounds like Konis might be the right move. Would I have sufficient travel with stock strut hats and the Eibach springs paired with Koni SAs or should I be looking at a street plate and/or stock springs?

I actually made spacers to adjust where the top of the shock mounts to the camber plate to allow me to be at 13.5" up front with 60% of my travel as bump and 40% as droop.

The Konis work fine with stock/unmodified everything with Eibach or Dinan springs (both of which are also flat ride incidentally-- unlike every other spring package for the car that I know of).

[WoGGo]

... which is why for my softer, street M3 I run a twin tube (Koni Yellow) and a soft springs (Dinan) with a bunch of travel, and for my more hardcore/track M3 coupe I run a monotube (Ohlin) with a stiffer spring... and front ride height determined 100% by optimizing the available travel.

Would it be beneficial to go with the pre-adjusted Konis from Dinan?
