Completed: DIY DRC removal/swap with Koni Yellow Sports....

[4.2Crew]

Cool. I have put Koni's on all my cars since 1985 and they have always been great. Question - did you take a ride height measurement before and after? This could be a direction I would go when my DRC dies knockknock. Coil overs are the snizz, and yes, they can allow you to put that ride height where it looks the best (but what most often is put where it is not best for the car....), they also allow corner weighting, simple spring rate changes, etc., etc., but every coil over suspension I have had was "set it and forget it". If this kit is close to that setting, then it is a very viable option.

Yes, I took measurements from the axle center to the top lip of the wheel wells on all 4 corners 10 minutes prior to tearing into it...

The Koni's product numbers are:

Front: 82-2516sport
Rear: 82-2526sport

The fronts have about 2.5 full turns of rebound dampening adjustability and the rears have about 1.25 turns... I set the fronts at 1 turn from softest, and rears at 0.5 turns from softest.

Also, the Koni fronts have only one lower perch groove... Easy enough to cut a groove if ride hieght needs adjustment. The Koni rears have 3 grooves (approx 3/8" apart)... I chose the middle groove which yielded an oem rear ride hieght.

So when done, the setting was how close to stock ride height? I would imagine if a spring compression measurement was taken before removing the springs from the DRC, and then matching that to whichever groove on the Koni yielded the same measurement, and then provided that the perch to bottom mount centerline measurement is the same (Koni probably copies it), then it should be close to stock ride height. Was that the case for the front?

Please give a 1000 mile report. It will also be interesting to see if you feel the need to upgrade the swaybars, since DRC is supposed to be an "active swaybar" there when you need it, and not affecting ride quality when you don't.

Lastly, again, that lift is killer!

Thanks for the report!

To answer your questions:

Yes, the height is within 1/16" on each corner as before the swap...

Compressed spring measurements: Short answer, yes... I wasn't too concerned about the compressed measurement, but it was within 1/4" on fronts and rears...

I drove the car about 60 miles today to get the alignment trimmed back in after the swap.... Wow, what difference! Quiet, compliant, smooth, sporty and luxurious ride! I can tell the DRC did assist the sway bars... Not night and day, but there is a difference.
