Both work really well!
The value to the Koni's: they are adjustable. You wont be able to run your springs with them however. The Bilsteins are pretty agressive on the valving and work really well with your current springs. B |

Brad, why won't you be able to run the springs he has with the Koni's? I eventually need to do the shock and spring thing, just wondering.

I've got 140's too. So, what springs work best with Koni's for sport/occaisional A/X driving? Thanks. (IMG:style_emoticons/default/biggrin.gif)

**Somebody** needs to contact Koni (Jeroen/Timo) and let them know the perch they weld on is set too high (even for lowered springs) I honestly believe they welded the perch on based from a worn out set of stock springs.
Bilsteins have a 5 way adjustable "clip" that sets the ride heigth. B |

Well this is strange.
I'm running 140-lb springs (lowering, Weltmeister, I believe...) on normal Koni reds. And I've swapped in two different sets of Konis over the years. All of 'em work. Is it the springs? Whatever, the car sits right down and works well. Well... pete Attached image(s) |

Umm.. Nobody sells Koni REDS!!
I'm referencing the Koni yellows. They stopped selling the Koni Reds some time back (as far as I know) The Reds came with a plastic spacer that I used to trim to get the corner weights correct without threaded perches. B |

I've had both on my car, and here's my take. The Bil's are a great compromise. That being said, they are a COMPROMISE. When I thought I'd use the car to putt putt around on sunny days, hit the Dairy Queen, enter a few car shows, and try that auto cross thing, the Bil's were great. Once I was bitten by the auto x bug, I switched to the Koni's, sold the Bil's and have never looked back.
Bottom line: if you are serious enough about auto cross or time trials or other track activities, go with the Koni's, as you'll probably end up serious enough to want to learn how to adjust them to your best advantage. If auto x or track stuff is barely hitting your radar, the Bil's would be better all around, just install and enjoy shocks/inserts. |

I had the Bils with 100# springs. The adjustable perches were Great! The Bils were wonderful although my wife complained it was too stiff for her... (but what does she know, eh?) (IMG:style_emoticons/default/biggrin.gif)

These are not Koni sports that Barry has.
He is talking about the Really old adjustable only once you pull the spring and completely compress the rod and turn to adjust. Shocks seems to be in good shape and not sure what his ride hieght ends up being. My take on cars is figure out what you want to do with it. make no compromise either track it, Autocross it or keep it on the street with a set up that won't jiggle the coffee out your cup. (like we got cup holders) (IMG:style_emoticons/default/blink.gif) The Koni's that Barry has at least have the ability to crank up the reboud stiffness for the 2 or 3 AX events he attends yearly. Bilstiens are stiffly valved and can beat you up a bit but defnately keep the rubber on the road. So the poison I picked in 200# rear coilovers and Koni reds that are externally adjustable. Hey they still work. But plan on going to QA-1 shocks soon. 21mm t bars Koni sports up front. |

Be careful with the QA1's. Remember this: they came from the dirt track world not the road car world.

Umm.. Nobody sells Koni REDS!! B Well, alrighty then! I think you mean nobody sells them NEW. (IMG:style_emoticons/default/biggrin.gif) I just picked up a set of VERY nice used (from the looks of it, barely) Koni reds at EASY. Before I put them in, where would you set them for street/occasional autoX use, oh great Brad-holio? (IMG:style_emoticons/default/flipa.gif) For reference, 911"M" front suspension with stock torsion bars, 22-mm Weltmeister anti-roll bar up front (no rear bar) and YES there is understeer in my setup...a rear bar may be in my future... As for the great Bilstein debate, I only had limited experience until one of them failed at high speed, bottom attachment point just shearing off nicely. (IMG:style_emoticons/default/sad.gif) Took em back, shop said they'd seen it before with Bilsteins and put me on (used) Koni reds, which I have been happy with ever since -- though I think I am going to have my first pair rebuilt and put them on a shelf...shelf life issues? Since then, however, I've never heard anyone else talk about shearing Bils and a lot of people (me included) like 'em in 911s and 914s. pete |

Set them on stiff (rear)
Correct: NO NEW KONI Reds! Absolutely get them rebuilt. Have them step up the rebound valving and the bump side a tad from stock. Shelf life: shouldnt be an issue. B |

Koni yellow adjustables, 21mm torsion bars, stock sway bar up front for adjustablility at AX and TT.
Bil sports set at the 2nd from bottom perch, 180# springs no rear sway bar. here is how the car corners at speed (IMG:style_emoticons/default/biggrin.gif) so depending on what you want to do either will work or in combination. If I go to Konis on the rear I will go to 200# springs with threaded collar to set ride height were it belongs.....in the weeds as it is now.

So I guess my koni adjustables are no bueno with the 140# springs I just bought great another extra part (IMG:style_emoticons/default/chair.gif) ...the Koni Yellows "will" work with the 140# springs, the problem that Brad mentioned is the height issue, not a compatibilty issue. see my thread on making Boge shocks "adjustable" ride-height wise: mueller's mickey mouse engineering (IMG:style_emoticons/default/smile.gif) in the picture below, the top shock has the perch in an elevated position, from Brads post, it appears that the Koni Yellows have the perch even higher, so that the rear of the car will ride too high. By lowering the perch you can have the rear of the car at a more normal height. (IMG:http://www.914world.com/bbs2/uploads/post-2-1119289815.jpg) |
