Eibach/Koni vs. Bilstein PSS10 for a street setup

[old///MFanatic]

No. Switching from the Koni’s to B4 Bilstein’s will add comfort, and at zero loss in performance

Unless I’m mistaken he said he had Koni Yellows(SportAdj). Bilstein B4 are their old named Touring line damper. Bilstein Tourings are a decent step down from Koni Sports performance wise.

I currently run Koni Yellow/Eibachs…

Is switching to Dinan springs going to be any more comfortable at all?

It's possible they're the same shock body, but all of TCK's Koni's are valved to TCK specifications-- so not the same part AFAIK.



That's the setup I have on my M3 wagon. Excellent DD setup IMO.

Is it worth saving up for the TC Kline SA set up for a car that will most be used for the street with the hope of getting to the track 3 times a year or would the Koni/Dinan set up suffice for a couple of years?

Koni > KW V2 was nice upgrade, don't waste you time with PSS10s on the street for the track there are several more capable kits with linear springs.

Would normal Koni Yellow SA's in front with the TCK SA's in the rear and Eibach springs still be a good match on a coupe?

Yes.

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).

Any shop that rebuilds Konis can rebuild GC. PSI in Sonoma is one, True Choice is another. Honestly I wouldn’t bother having GC rebuild them.

Thanks for those. I'll check them out.

Have you considered KW V2s OP?

[timmo]

GC won't actually rebuild them - when I called and asked, they said to reach out to any of the shops that rebuild Konis

A great thread, I was looking for feedback on PSS10's, So my Story is that I have been on GC Da's for almost 7-10 years and they were great, until first the rear shocks started leaking and then the fronts. The rears were an easy replacement from GC but the fronts a whole different story. They sent me wrong shocks twice and after so much back and forth I installed the last set of front shocks which i went from DA to SA's as I was done with the complication. Well now the fronts make a weird sound like the springs are turning and not sitting snug. We cant figure it out even though the GC camber plates were rebuilt and good as new. I am so glad I never returned the original DA shocks to GC, maybe i ca send them for a rebuild to Koni and or Fatcat Motorsports.

Any way, I am thinking of changing coilovers and going for a commercial setup that has easy and quick replacement and or rebuild services, Choices are KW V2/V3 with GC/TMS camber plates, PSS10 with GC/TMS camber plates or Fortune auto 500 9/11kg springs. I am leaning towards the PSS10 or Fortune Auto 500. What would your advice be for someone who feels he is getting older and wants to enjoy a nice tight yet not too uncomfortable ride on the street and step in for an occasional lap or three of the Bahrain F1 Circuit.

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.

Oh wow! That is nasty only after 3 winters. I am thinking of getting the PSS10 and if i do i'll be taking them straight to the powdercoaters to coat.

[yhp2009]

Anyone actually drive in big cities like NYC using these setups? Wondering if its a mistake to get our cars lowered in such environments

[EthanolTurbo]

Get a TCK SA kit with 350/500 springs. Will ride better than anything mentioned.



Maybe don't recommend something you haven't even tried, especially when it contradicts exactly what the OP said in the first post..?

I just said I have them on another car, it's not a stretch considering I own the dampers on the following 3 series. The dampers are extremely well made. I've also driven them on an Evo 9. I'm recommending them because Ohlins are top tier dampers and you can always get them revalved to be more comfortable.
