I used KYB GR2 struts on an old minivan of mine. Worked very well for the price, nice improvement over the 100K stock dampers. Far superior to anything in their price range, like Gabriels, but what isn't? They were a bit harsh, but I like having a sporty minivan. I hear the AGXs are also nice, but they're up near Koni price territory, no deal for me.
I was considering myself them before I happened on a used set of MTech Bilstein Sports.
I also rode them on an old Honda Nighthawk S, far superior to the Showa units that Honda usually specifies.
