I have a question for those that have experience playing around with multiple settings in the rear.

When I first got these shocks a year ago, I set the rear ones exactly 3/4 turn from full soft. (~ 30%) It did something funny to the car; the rear of the car was extremely bouncy, as if the car was on a pogo stick. It was almost as if there was no rebound damping. So I set them at full stiff. The car now has a slightly stiff ride, but it did solve the issue.

Has anyone else experience something similar with the Koni yellows paired with the stock springs? Also, how durable are Koni's? am I causing premature wear on the shocks by setting the rear full stiff?
Interesting! When I got these shocks in early 2005, the 25% from soft set up worked very nicely for me with the stock springs. I still have no problem with them at all. The set up in both the front and rear is a little jolting over sharp bumps, but the wheels are very well mated to the road, and they take large and sharp bumps without losing any control.

I never had the problem that you are describing, but it is very possible that the stock springs are no longer the same. It is also possible that you have one or more bad shocks, or there is an installation problem. In the end, I don't think that you should be having this issue with the Koni yellows. They should be stiffer than that.

In answer to your question about durability, I don't think that having them at full stiffness will cause premature wear. In the 80,000 or so miles that I have been running these shocks, the rears have held up great. I just insptected them again last month. They ride fine as they always have, and there is no oil leaking from them. The fronts have been replaced once for blown seals. at about forty thousand miles of use.

Best of luck, and check the install. It might be that there is an issue with the suspension itself since installing the rears requires alot of moving stuff around to get them in.

After trying monotube Bilsteins (H&R coilovers) and Ohlins DFVs, I noticed how much better the ride quality was compared to Konis. Both setups were firmer with much higher spring rates (457 and 610 lbs respectively), so the ride was expected to be worse, yet they were more compliant and less upsetting than than Konis.

Still, recently I reinstalled the Konis in attempt to get the car back to stock trim, and they are riding better that last I had them on the car. I am currently running 65% stiff front (1 3/4 turns from full soft) and 75% stiff rear (2 turns from full soft). This setting seems to ride better than full soft or full stiff (both which I tried in the past).
