Theres always been a debate between these 2 products. Just want to add that KYB Agx do lower the car more than Koni yellows. Owning both products, they are the same in length, but KYB Agx sits the springs lower than Koni yellows..which gives the car a sportier look....also i find out Agx to be more comforting, where the konis are much stiffer.
so I guess it depends on what the driver wants.
