I didnt asked about the quality of konis vs. kyb... i just wonder how happy you guys are with konis cause id like to have a set for my car too :) What springs are you running? Anyone with canucks, sprint or intrax springs? I like the drop of the canucks thats why i didnt put on the Eibach prokit on mine...
Weba, does your black car got original konis that were sold for our cars or have you done that build too?

I'm running Eibach on both setups. I don't feel the koni's are that harsh... yeah they can feel pretty rough when you have the dampening cranked up, but if I take that out they feel quite fine.

Going off the numbers if you have the J-body setup the compression dampening is quite firmer than the original Beretta spec... Not sure why they did that with the Beretta being the heavier car but they did for some reason. SO what I'm running may be firmer than say Mike Pride's GTZ since he has original Beretta Koni's. The Mitsubishi ones are somewhere in the middle and the only person running those is Robert right now on his GT.

michi, I have the J-body ones fitted. Sprints at front and Eibach at rear, both pairs are about 10 year old.

I doubt the 95-05 J-Body Konis that much more harsh (if at all) than the Beretta specific versions. My GT (on eibachs) and Mike's GTZ (on sprints) pretty well ride like a buckboard. Both are equipped with the Beretta-Specific Konis on all 4 corners.

According to Koni spec the dampening rate is much higher for the J-bodies.

Looking at the data, dimensionally the Beretta and Cavalier units are similar with Cavalier being ½ to ¾ inch shorter but the Cavalier is nearly double the rebound and compression damping forces of the Beretta. Although the valving of the Eclipse unit in rebound is in between the other two cars

I can confirm by my back-o-meter that Pride's racecar is quite the wild ride. Not sure I'd want to drive/ride in something more harsh than that :D.

Pauly recently did this with the Mitsubishi inserts and the total cut off for the strut housing is 64mm vs the Koni measurement of 40mm. These inserts are shorter than the J-body's. This ended up with a insert stickout like this.

You want to have at least this much of the insert visible.
