KW and Hotchkiss sway bars. I must admit it is odd to drive the car without the worry of a clunk or DRC oil spill as they always came at inopportune times.
In one year, I had my car at the shop 5 times for the DRC. Multiple letters to AoA did no good. It ended up wasting a lot of my time with the constant trips to the service shop.
I will note that AoA did finally come through and reimbursed me for the KW costs and sway bars. However; I'll never get my time back that slipped through the hourglass.
With that said, there are owners that have had a good experience with the DRC, and the new new new new recent DRC parts and install.
It seems like it comes down to what you are looking for in a suspension system, and how much tolerance/patience/time/skill you may have to deal with issues.
Less than .02 worth I'm sure but I had some time to kill and thought I would excercise the fingers.
