most that weren't going to a coilover setup went with KYB AGX, as opposed to Koni Yellow.
Even though the Konis are supposed to be the better shock, I believe one of the main advantages of one over the other was ease of rear adjust-ability. The AGX has a dial at the base of the shock that you can reach from under the car. The Koni yellows to my understanding have to be removed off the car to make adjustments. (at least for the model of rear that fits our cars, may not be the case for other applications).
