Eibach/Koni vs. Bilstein PSS10 for a street setup

[0-60motorsports]

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.

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).

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.

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.

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?

[Advorsor]

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.

I currently run Koni Yellow/Eibachs…

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

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 am pretty sure B4's are monotubes which are better than old school koni twin tubes in all areas. The marketing name touring vs sport means little.

B4/Tourings are not as good as the B6/HDs or B8/Sport. The B6 and B8 are well known as being more equivalent to the Koni Sport Adj(Yellows) performance wise.

Mono tubes aren’t just better than twin tubes, and the B4s are twin tubes anyway.

Oh wow that was confusing. Now I see it says the B4's are monotubes OR twin tubes.

How do you know?

Well since no one else yet has posted to confirm. I’ll play.
I’ve worked in the past for a company and sold both brands, used both for decades, it’s pretty much explained in the link I posted above and it’s all over the tuning sites.
If that’s not enough just look at the pricing and decide. The Bilstein B4/Tourings retail for half the price of the B6/HDs, B8/Sports and Koni SportAdj (“Yellows”).

I notice the KW V3 don't come up much in these conversations. Is there a reason why? I run them on one of my other cars and really like them in that particular application. Good range of adjustability and not too firm IMO. But curious as to thoughts on our e46 m3s.
