Almost every non honda-tech article I've ever read credits a car's feel and responsiveness to somewhat aggressive low speed bump valving. Also, many articles have mentioned that bump valving is what will keep the car from bottoming out, and I've experienced bottoming out in Koni equipped cars that weren't excessively lowered. I've sat in cars with monotube dampers which naturally have more aggressive low speed bump valving and the difference is obvious, they are much more responsive and have better steering feel. People seem to avoid discussing the Koni's compression valving. I remember a post long ago in the rr/ax forum where an avid autocrosses switched out some high end jdm shocks for race valved Koni's and was confused because his car didn't feel as solid and tight under acceleration, braking, and turning. None of the responses mentioned the bump valving might have been the factor. The most obvious difference between the graphs I've seen so far is that most of the Koni graphs have a lot less bump valving throughout the board than the rest of the shocks. Please don't flame me, educate me.

They might look nice on paper but internally they're of lesser value IMO.

I had a set of the Sports on my DC and they faded on me during a session at Buttonwillow. The left rear damper just gave up mid corner and the car felt like it lost a "leg" and completely compressed as if it had no damper. I pulled into the hot pit to check it out because it felt like something had gone loose, everything checked out fine mechanically but I had lost my confidence for the rest of the day.

I have since lost that car due to theft and now have a DA on Koni/GC.

actually tried this on a 2650lb integra before. 300/250 works really well with those shocks

im surprized how little i understand after looking at the sample link. im just looking for the strut that has the strongest rebound damping. i have cheap stiff dropzone coilovers.the stiffness does not bother me . but the new stock struts dont have rebound damping. i researched this so much but still dont know? MY GUESS IS KONI YELLOWS? anybody have some advice or does this sound like a bunch of rabling?

Here's one for a Bilstein shock I had rebuilt - sorry for the oversized pic. The engineers at the Poway facility are very helpful BTW:
