Bilstein or Koni

price not being an option.. what do you guys think? They are going to be used with H&R Sport Springs.

Bilstein Sport (always liked them and never had a problem)

Koni Adjustable (heard they have better rebound control, though i've pulled them out of cars because they were blown and leaking)

that's great.. but why?

My cousin has used both and when I had asked him the same question he said he definetly prefered the koni's. Don't remember why I think he said the where a lot stiffer and offered a better ride. I think. I am also going to go with koni's for my ride. *th-up*

In my research, I've never really found a good reason to get the Bilsteins. I'll elaborate, and please someone contest me if you have solid data against anything I say.

In valving, the Bilsteins are stiffer than the Konis in compression, but the complete opposite in rebound. Because of this, the Bilsteins aren't able to handle spring rates higher than the typical H&R Sport or Eibach Pro-Kit, because they can't control the oscillation. Meanwhile, thanks to already-firm plus adjustable to be even firmer rebound on the Konis, they will handle just about any rate you throw at them. The softer compression rate also lends a much more comfortable ride with the Konis, as undulations don't provide the harsh immediate feedback you get with the Bilsteins. Also many note that after a bump the Koni equipped car will settle immediately, while the Bilstein car will take an extra moment (due to the rebound difference). This makes the car feel much more composed. Keep in mind however that Bilsteins can be revalved, but at a cost that makes them more expensive than Konis in the end.

Another large difference between the two is that the Koni dampers are a twin-tube design, which theoretically lends a longer piston stroke and therefore more travel. Suspension travel in the front of our cars is very sparse, so this is an important advanatge. Plus, the bumpstops with Konis are external, and can be trimmed down to aid some applications. The Bilstein stops are internal, and cannot be modified, at least by anyone but Bilstein. On very low cars Bilstein Sports bottom out excessively, which proves these theories correct.

This "knowledge" is compiled from years of reading forums and speaking with Bilstein and Koni representatives and even a retired Bilstein engineer (who interestly enough convinced me that the Koni design is better). Take it all for what it's worth, of course.

with the billy you can have valving made stiffer than what they are now S.O that is what I have told.And Koni's are very good too but dou to the adjustable is why they leak but still a good shock.

I can vouch for that.

Haha I remember on the Midnight Cruise when we went over a big bump, you were PISSED on the radio. :D

ahahaha.. really? what did I say? "OW?"

why does ever suspension product for BMW have some kinda compromise to quality or performance.

*shiner*

Depends on how many pot holes are near you.

I'm looking into the konigsport coilovers from ami..

Slowered318 03-31-2005 04:08 PM

huge holes that can write your car off!

Everyone thinks i'm constantly high and drunk behind the wheel, I just drive real slow and swerv all over the road like a moron. i'm thinkin of using an M3 rack to speed up my pot hole reaction time

I don't see why everyone likes coilovers.. isn't bmw known around the world for building great handling cars or is that just BS. why would anyone wanna change the design that dramatically.

I was in the same boat as you, and everyone recommended the KOni's so I bought them. Once I install them, and drive with them for a while, I'll have something to contribute to this thread.

If the original design allowed me to dump my car, then I would leave it.
