This is a great thread. I currently have the Eibach Pro springs on stock suspension. Once my suspension wears out, I'm considering the Koni yellows. Would this be a good combination for street and autocross? What setting would be good for 50/50 street/autocross?

Yes Mr. Cooper. Maybe 3/4 turn F and 1 turn rear. You don't want the rebound too slow (stiff) and not be ready (full travel) for the next compression.

Honestly, if the Konis are brand new, you could even start at full soft and turn them as they age. The eibach pro kit isn't that high of a spring rate nor does it lower the car that much.

Eibachs are the best aftermarket spring maker, imo, so you couldnt go wrong getting a set to match with new Konis, then run the konis full soft, tightening them a quarter turn every 5k-10k as they age. My suggestion.
I think Eibach was making the springs (shocks were made by Sachs) for AC Schnitzer but with Schnitzer's specs as they are considered "softer" than the Pro Kit (I think)!
Thanks TboneM3!!

Ah, love this forum.


My set of Koni yellows are in transit, and I've been thinking of what settings to run them. I have Tein springs which I believe are a bit lower than some other aftermarket options, so I'm thinking of setting the Koni's a bit firmer.

Anyone pair koni & tein and live to tell the tale? I ran them on my E36 with H&R sports and kept them at full soft, actually rode really well.

Lower doesn't always mean stiffer and that's the case with the Teins. They're not a great spring because they're too soft for how much they lower the car.

Lowering springs will reduce the travel of your suspension; it's wrong to always associate a lowering spring with a stiffer spring notwithstanding the fact that yes, all springs get progressively stiffer as they're compressed. So in the case of Tein, you have a spring that's shorter than stock, but not stiffer (or not much anyway).

You chose your dampening based on spring rate. I wouldn't run the Konis much off of full soft as I don't believe the Tein's spring rate is much, if at all, heavier than stock. Your car being lower mean less travel, not that it's stiffer. You'll just be hitting the bump stops more, so make sure your bumps are nice and new.

Having said that, I wouldn't use Teins if you're at all serious about suspension.

Awesome, thanks Tbone! I will most likely run them on full soft then. The Teins were cheap on craigslist and probably won't stay on the car long-term.

My car is a daily driver (~80m highway commute per day) so I am not really that "serious" about suspension in terms of racing, etc. I've got my E30 for crazy handling shenanigans

No worries. Ya the drop from teins looks amazing, but drive fast and you'll be on the bumpstops.

Wanted to bump this thread as I'm looking into getting some Konis as well to address a leaking rear shock.

I'm on the fence on getting springs for my car or staying with the stock springs.

H&R's are on sale at ECS right now and was wondering if anyone here has any experience running those with the Konis, and what kind of ride quality it provides.

I'm mostly trying to retain a stock feel in terms of stiffness. I don't want to make the ride too harsh as I have a child.

Thanks guys!

H&Rs crash a bit up front imo. I think Eibach, CSL and Dinan are better choices. But they're decent. Wish the fronts were stiffer rate.

I agree with TboneM3.

Why you want to change springs?

If you don't want lowering springs keep the oem ones that are the best!
