I'm going to put on the Koni/Eibach internally adjustable shock/springs. I was looking for suggestions on setting some might have tried in respect to the Konis. I'm only concerned with performance, not ride comfort. The only suspension mods are wider 18" Z rated street tires and drop links. I looking for maximum performance when driving in DE events. It was suggested my the seller, one of the big three, to try full stiffness on the front shocks and 80% on the rear. Any other suggestions?

I set mine at 3/4 hard all around. No fiddling done to prove/disprove the usefulness of this setting. I've got "old" Eibachs in front the the former fronts on the rear. Tuning shocks to springs is key so if the new Eibachs are stiffer then more shock stiffness there would make sense.

Frankly not sure if this is really important, but it was suggested and I did it: Make sure the rebound rates are matched on car ends. That is, press the shafts all of the way in and then let them extend. They should reach the top at the same time. Also, do this with the shocks vertical with the rod up. The internal workings don't like being compressed upside-down. At least that was my experience when messing around with some used ones.

Dave the only adjustment you can make is to rebound ...... rebound only , the compression is factory set and does not adjust . That is probably one of the reasons some people find the Koni harsh on the street even though they adjust it soft or hard the resistance to compression does not change . There are those who believe that with too high a rebound setting the front end will ratchet down under hard braking and an irregular road surface . Perhaps you should contact Koni for their recomendations but I believe that something less than full hard on rebound would work best with the factory compression setting balancing compression and rebound .... otherwise why have it adjustable at all ? Koni speaks to using the adjustment to compensate for wear over time .

Okay,
Thanks for the suggestions and explanations

Dave,
In setting rebound as Jim mentions, the discussion had with Koni re the 8240-1085/6 fr/rear shocks was 0 turns for stock, 1/2 to 1 turn for ~20% stiffer perf springs, and 1/2 to 3/4 for perf driving on stock springs: I'm happy at 5/8 turn, the max being 2.5 turns. Seems as if 1 turn would be a reasonable max. start point for the Eibachs.

Thanks Garth.

Dave - I have the Koni (internally adjustable)/Eibach setup also. The first 2 years I had the Koni's set to full soft all around which was good for street driving. I did notice that the rear rebound was too soft at times. It felt like the rear end was going to jump off the ground after coming out of a big compression. I also started going to DE's and decided I wanted something a little stiffer on rebound especially in the rear. I adjusted the fronts (1.5 turns lock to lock) to 80% max (1.25 turns from full soft) and adjusted rears (2.5 turns lock to lock) to 60% max (1.5 turns from full soft). This setup felt a lot better on the track and the rear end no longer feels jumpy. Overall it's less cushy but I kike it that way. Good Luck!
