I went from KYB AGX's to these so don't have much feedback on direct stock to Viking but I must say I love the ride quality. Even with it as low as it is now it is great over bumps around town and feels more stable on the highway hitting bumps. These blow away the KYB's and the KYB's were better than stock so..
They also feel much better cornering and launching, weight transfer is nice. The only thing is I don't like the way they mount. The combined force of the shock and spring is all transmitted to the central steel bushing in the upper strut mounts in the front. I have been noticing a clunking noise on the drivers side that is driving me nuts, think I should replace the strut mounts. I would suggest to anyone doing these get new strut mounts because even if they look fine the extra load to the center is going to change it.
